Use your iPhone as a Samsung TV remote
Connect an iPhone to a compatible Samsung Smart TV, approve pairing, and troubleshoot discovery with SpaceNode TV Remote.
Connect an iPhone remote app to an LG webOS TV
A practical LG webOS setup guide: same-network checks, on-screen pairing, remote controls and limitations.
iPhone TV remote app not connecting? Check these first
Work through local network permission, TV pairing, guest Wi-Fi and standby problems before changing remote apps.
Use your iPhone as a Roku remote
A compatible Roku TV or player can receive network commands from your iPhone. Navigation and volume are different capabilities: a Roku player is not the same as a Roku TV.
Allow Local Network access for an iPhone TV remote
Local Network permission lets the remote app discover and communicate with nearby TVs. Internet access and Bluetooth permission are separate settings.
Connect an iPhone TV remote using a TV's IP address
Manual connection is useful when a supported television is reachable but absent from discovery. It requires the TV's current local IP address and the correct brand.
Type on your TV with an iPhone keyboard
An iPhone keyboard can help with searches on compatible TVs, but the active TV app and input field must accept remote text commands.
TV remote app connects but volume does not work
A successful connection does not prove the app can control the active audio output. TV speakers, a soundbar and a streaming player can each use different volume paths.
Why an iPhone remote cannot always turn a TV on
Turning a TV off and waking it from standby are different operations. A network remote needs the television to retain a reachable network or supported wake capability.
Lost your TV remote? What an iPhone can and cannot do
Your iPhone can replace some controls on a compatible TV that is already connected to your network. Initial Wi-Fi setup and pairing approval may still require physical controls.
How to print a PDF from your iPhone
Print a PDF with built-in AirPrint or Smart Printer, choose pages and copies, and check the preview before printing.
“No AirPrint Printers Found” on iPhone: a checklist
Check AirPrint compatibility, network access and printer readiness when your iPhone cannot find a printer.
Print Google Drive files from an iPhone
Make Google Drive available in the iOS Files picker, open a document in Smart Printer, and print with AirPrint.
Print photos from your iPhone without unexpected cropping
Choose the original image and inspect its paper preview before printing. A photo's proportions may differ from the selected paper, causing borders or cropped edges.
Scan a paper document and print a copy with your iPhone
Use your iPhone camera to scan a page, review the resulting document and print it through AirPrint. This is useful when your printer has no convenient copier controls.
Print a webpage from your iPhone with a readable layout
Webpages can produce different printed layouts from what appears on screen. Preview the printable content before using paper, especially on pages with menus or long comment sections.
Print an email attachment from your iPhone
Print the attached document itself when you need an invoice, ticket or form. Printing the email conversation may include headers and omit the attachment's full pages.
Print only selected PDF pages from your iPhone
The iOS print sheet may let you select a page range instead of printing the whole PDF. The preview's page order is the reference, which can differ from printed page numbers.
Print double-sided from an iPhone: check printer support
Automatic two-sided printing requires a compatible duplex printer and an option exposed in the iOS print sheet. Installing a printing app does not add a duplex mechanism.
iPhone says printed but nothing came out: check the print job
Sending a job is different from a printer producing paper. A sleeping printer, paper mismatch or an existing queue can delay a document after the phone submits it.
Create a Wi-Fi QR code on your iPhone
Make a Wi-Fi QR code with the correct network name and encryption, test it, and share it with guests.
Export QR and barcode scan history to CSV on iPhone
Export saved codes from SpaceNode QR Code Scanner to CSV, understand the columns, and open the file in a spreadsheet.
Scan a QR code from a photo on your iPhone
Read a QR code from a saved image, check the decoded result and troubleshoot blurry or cropped codes.
Create a website QR code on your iPhone
A website QR code opens the URL encoded inside it. Use a complete public address and test it before adding the code to a poster, package or business card.
Create a contact QR code for a business card on iPhone
A contact QR code shares structured details such as a name, phone number and email. The receiving phone still controls how those fields are shown or added to Contacts.
Create a plain-text QR code on iPhone
A text QR code carries a short note directly, without requiring a website to display it. Use it for simple instructions or labels that should remain readable without opening a link.
Create an email QR code on your iPhone
An email QR code prepares an email action for a compatible reader. It does not send a message automatically or guarantee that a mail app is configured on the receiving phone.
Create a phone-number QR code on iPhone
A phone QR code lets a compatible reader offer a call to the stored number. The person scanning remains in control of whether to start the call.
QR code not scanning on iPhone: image or link problem?
First distinguish a code that cannot be decoded from a decoded link that will not load. Camera focus and contrast fix the first problem; website access is a separate issue.
Create a QR code for a restaurant menu on iPhone
A menu QR code usually points to a webpage or public PDF. Host the menu first, then encode its address; creating the QR image does not upload or host the menu for you.
How to scan a paper document to PDF on iPhone
Scanner turns a paper page into a PDF by detecting its edges and correcting the camera perspective. A clear capture matters more than a strong filter.
How to scan multiple pages into one PDF on iPhone
Capture related pages in one scanning session to make a single PDF. Check their sequence before sending a contract, application or set of notes.
How to turn document photos into a PDF with Scanner
Existing pictures of documents can become a PDF without photographing the originals again. Importing a photo preserves only the detail already present in that picture.
How to copy text from a scanned document on iPhone
Scanner uses on-device text recognition to extract text from saved pages. The result is useful for copying passages, but it still needs a check against the original.
How to add a signature to a scanned PDF on iPhone
Scanner lets you place a drawn signature on a document and share the resulting PDF. Check the recipient's signature requirements before using a drawn mark.
How to scan both sides of an ID onto one page
Scanner's ID Card mode arranges the front and back of a card on one printable sheet. It is useful when a recipient requests both sides in a single file.
How to scan a passport photo page on iPhone
Scanner includes a Passport mode for capturing the passport's photo page. A readable digital copy can help organize travel documents, but it does not replace a passport.
How to merge scanned documents into one PDF
Scanner can combine separate documents when pages were captured in different sessions. Merging is useful for an application that needs several supporting documents in one file.
How to fix rotated or hard-to-read scanned pages
Use Scanner's page editor to rotate, reorder, delete and filter pages. Editing is most effective when the original capture is already sharp and complete.
What Scanner exports to Word, Excel, PowerPoint and text
Scanner can export DOCX, XLSX, PPTX and TXT files. Word, Excel and PowerPoint exports contain page images; TXT contains recognized text rather than the page layout.
How Scanner's optional iCloud sync works
Scanner can sync documents, page images, recognized text and folders through your personal iCloud account. This optional feature requires iOS 17 or later and an eligible subscription.
How to lock Scanner with Face ID or a passcode
Scanner's App Lock covers the document library until you authenticate when the app opens or returns from the background. Available authentication depends on your device.
How to find a GIF by keyword on iPhone
GIFFF searches animated GIFs by keyword. Describing the reaction you want usually works better than typing a long sentence from your conversation.
How to choose a reaction GIF that fits your message
A useful reaction GIF communicates one clear feeling. GIFFF's search and categories let you compare several options before replying to a message.
How to browse trending GIFs and keep useful finds
GIFFF's trending feed is useful when you want to discover animations without a specific search term. Save promising finds so you do not have to locate them again later.
How to reuse favorite GIFs across GIFFF, its keyboard and Messages
GIFFF shares favorites between its main app, keyboard and iMessage extension on the same device. This keeps frequently used reactions close to the conversation.
How to add the GIFFF GIF keyboard to iPhone
Adding GIFFF as a keyboard lets you find GIFs from supported typing screens. Selecting a GIF copies it so you can paste it into a compatible message field.
Why the GIFFF keyboard asks for Full Access
GIFFF's keyboard needs Full Access to download GIFs for search and copying. This is a separate iOS permission from simply adding the keyboard to your keyboard list.
How to send a GIF with the GIFFF iMessage app
The GIFFF Messages extension lets you browse and insert GIFs without leaving a conversation. It is separate from the systemwide GIFFF keyboard.
How to save an animated GIF to Photos on iPhone
GIFFF can save GIFs to Photos so you can use them later outside the app. Save the original animation rather than taking a screenshot of its preview.
How to share a GIF from GIFFF to another app
GIFFF uses sharing options to pass GIFs to other apps. Whether the result plays as animation depends on what the receiving app accepts in that particular screen.
Why a GIF stops moving after you share it
A still result often means you shared a screenshot, the destination shows a static preview, or that posting surface does not support GIF animation. Test the saved file before changing settings.
What to check when GIFFF search or previews will not load
GIFFF needs a connection to retrieve new search results and GIF files. Separate an empty search from a download problem before retrying the same animation repeatedly.
How to search for GIFs in different languages
GIFFF supports multilingual search matching. Trying both a local phrase and a short alternative can help when a reaction has different names across languages or communities.
How to make a scrolling LED sign on iPhone
LED Banner turns your iPhone screen into a moving text display. Begin with one short message, then adjust its appearance while watching the full scroll.
How to make a phone LED banner easier to read
Readable banners depend on contrast, letter shape, message length and speed. Improving those four things usually matters more than adding shadows or flashing effects.
How to adjust scrolling and blinking speed separately
LED Banner has separate controls for text movement and blinking. A readable scroll can still be hard to follow if the text disappears too often during the animation.
How to choose a scrolling direction for your LED banner
The direction of movement changes how a viewer encounters your message. LED Banner lets you adjust direction, but the best choice is the one that makes your actual text easiest to follow.
How to choose LED dot shapes and colors
LED Banner offers circle, star and heart LED patterns with text, background, outline and shadow colors. Use these controls to support the message while keeping the letters recognizable.
How to choose a font for scrolling LED text
A font that looks good in an editor can be hard to read while moving. LED Banner includes multiple font styles, so compare them using your complete message at its intended size.
How to make an LED banner in another language
You can enter multilingual text in LED Banner using your iPhone keyboard. Preview the actual characters because font support, spacing and reading direction affect the result.
How to prepare an iPhone LED banner for an event
A short LED Banner message can help you cheer at a concert or sporting event. Prepare and test it before arriving so you are not editing a long sentence in a crowded venue.
How to make an animated birthday greeting with LED Banner
Create a short personalized greeting, then show it on your phone or export it for sharing. A name and a concise wish often work better than a long scrolling paragraph.
How to export a scrolling LED banner as an MP4 video
LED Banner can render a design as an MP4 video for sharing outside the app. Review the actual exported file because it is the file, not the editor preview, that other people receive.
How to export an LED banner as an animated GIF
GIF export makes a looping version of your LED Banner design. Short messages and restrained effects usually produce a more practical file for chat sharing.
How to save and sync LED Banner designs with iCloud
Saved LED Banner designs can sync through iCloud so you can reopen them on supported devices. A saved design is different from an exported video or GIF.
How to convert a currency amount on iPhone
Currency shows an amount in several currencies using its loaded exchange rates. Choose the currency of the original price before entering the amount to avoid reversing the conversion.
How to compare one amount in several currencies
Currency lets you view several conversions together. This is useful for comparing a travel budget or a quoted price without repeatedly replacing the same currency pair.
How to prepare Currency for offline travel
Currency can calculate with previously saved exchange-rate data when you are offline. Load the currencies and rates before losing your connection, and remember that cached rates are not live quotes.
How to check when Currency's rates were last updated
The usefulness of a conversion depends partly on the age of its rate data. Currency's refresh settings show update information and available refresh-frequency choices.
How to calculate an expense before converting its currency
Currency's amount input accepts arithmetic expressions, allowing you to calculate a subtotal before converting it. Keep every number in the expression in the same source currency.
How to enter large amounts in Currency without extra zeros
Currency provides amount shortcuts such as 1K, 10K, 100K and 1M. They can speed up large-number input, but the displayed amount should always be checked before conversion.
How to read an exchange-rate chart in Currency
Currency's Chart tab lets you inspect a currency pair over different time ranges. A chart describes past rate data; it does not tell you with certainty what the next rate will be.
How to reverse a currency conversion correctly
To reverse a conversion, change which currency contains the amount you are entering. Reading the opposite row without changing the input can answer a different question from the one you intended.
How to estimate a travel budget in another currency
Currency can put a travel budget into a common currency so you can compare daily costs. It is a conversion tool; keep the actual list of expenses in a note or budgeting app.
How to compare overseas prices in your home currency
Converting two prices into one currency makes a comparison easier to read. To make the comparison useful, include known delivery charges and compare the same quantity or product variant.
Why your card charge can differ from a currency converter
A converter provides a reference amount, while your card issuer or exchange provider determines the transaction's final pricing. Different rates, timing and fees can explain a mismatch.
How to organize your Currency list for a trip
A focused currency list makes everyday conversions quicker. Keep the currencies for your current route near each other instead of scanning a long list for every purchase.
How to blur faces in a photo on iPhone
Blurri can detect faces in a photo and apply a blur effect. Automatic detection is a starting point; inspect the finished image before sharing anything that needs privacy protection.
How to blur a group photo while keeping one face visible
Blurri lets you exclude selected detected faces from photo blurring. This helps when you want one subject visible while hiding other people in the same frame.
How to manually blur a small area in a photo
Manual blurring in Blurri is useful for details that face detection does not cover, such as a name badge, address or small section of a screenshot.
How to choose between Blurri's five blur styles
Blurri offers Pixel, Blur, Motion Blur, Crystal and Hexagon styles. Compare them on the actual image because a decorative effect and a privacy-focused edit have different goals.
How to blur a photo background while keeping a person sharp
Blurri's background blur can separate a person from a distracting scene. Review subject edges carefully, since hair, glasses and gaps between arms can be difficult to separate automatically.
How to blur moving faces in a video on iPhone
Blurri can scan a video for faces, group detections by person and track selected people. Review the complete rendered video because movement and occlusion can interrupt automatic tracking.
How to blur supported objects in a video with Blurri
Blurri offers video targets such as screens, phones, laptops, documents and license plates. Detection depends on the object being recognizable in the footage and should be checked after rendering.
How to check a blurred video for missed tracking frames
A video can look safely blurred in most frames while exposing a face briefly during a cut or turn. A deliberate review is essential when concealment is the purpose of the edit.
Fast or Precise: choosing Blurri's video rendering mode
Blurri offers Fast and Precise video processing options. Use a short test to compare processing time and the actual coverage of moving subjects before committing to a long export.
How to hide a license plate in a photo or video
Use a manual photo edit or Blurri's supported video object targeting to cover a plate. Check the letters and digits at full size before sharing vehicle images.
How to check a screenshot before sharing it
Blurri's manual photo tools can cover selected areas of a screenshot. First identify all private details, since chat headers, previews and repeated names often reveal more than the main text.
How to find and share edited photos and videos in Blurri
Blurri's gallery collects edited media and provides photo/video filtering, sorting and selection tools. Use it to distinguish finished results from the originals you imported.
How to read and search a PDF in PDF Reader Pro
PDF Reader Pro provides page navigation, zoom and text search for PDFs. Search works best when the document contains a text layer rather than only photographed page images.
How to scan paper into PDF Reader Pro
PDF Reader Pro combines camera scanning with PDF viewing and editing. Capture a clear document first, then use the PDF tools on the saved result.
How to highlight and annotate a PDF on iPhone
PDF Reader Pro offers highlighting, freehand drawing, text notes and image insertion. Choose the tool that matches whether you are marking existing text or adding new information.
How to place a saved signature on a PDF
PDF Reader Pro lets you create, save and place a drawn signature on PDF pages. Confirm the recipient accepts this type of signature before completing the document.
How to merge PDF files on iPhone
The merge tool in PDF Reader Pro combines separate PDFs into one file. Review source order before merging, especially for applications with a required document sequence.
How to split a PDF by page range on iPhone
PDF Reader Pro can create a smaller PDF from a selected page range. This is useful when you need to send one section without sharing the rest of a document.
How to reduce a PDF's file size on iPhone
PDF Reader Pro includes PDF compression. The amount saved depends on the source, and reducing image quality too far can make a smaller file unsuitable for reading or printing.
How to add a password to a PDF on iPhone
PDF Reader Pro provides PDF password tools. Add protection to an authorized document, then reopen the exported file to confirm that the intended password is actually required.
How to add a watermark to a PDF on iPhone
A watermark can label a PDF as a draft, sample or internal copy. PDF Reader Pro can add a visible mark, but it does not prevent a recipient from copying or photographing the content.
How to extract text from a PDF on iPhone
PDF Reader Pro can extract text that is present in a PDF's text layer. A PDF made only of scanned images may not provide text through this tool.
How to turn images, text or a web page into a PDF
PDF Reader Pro offers separate tools for image, text and web-to-PDF conversion. Choose the source type first so the app can present the appropriate import or input flow.
How to check PDF Reader Pro's iCloud sync
PDF Reader Pro supports iCloud synchronization for PDFs and saved signatures. Verify a small example on each supported device before relying on the library for important work.
How to create your first invoice on iPhone
Invoice Dash turns business details, a client and line items into a PDF invoice. Check the content and total before sharing; generating a PDF does not send it or collect payment automatically.
How to add your logo and business details to invoices
Invoice Dash can reuse your business profile across documents. Set it up carefully once, then review the generated PDF rather than retyping your details on every invoice.
How to save client details for repeat invoices
Saving a client in Invoice Dash reduces repeated typing and helps keep invoices consistent. Verify billing details rather than assuming a contact's personal information is the correct invoice address.
How to reuse services and prices in Invoice Dash
Invoice Dash's reusable item catalog helps you add commonly billed work without typing the same description and price every time. Review quantities and rates for each new job.
How to turn an accepted estimate into an invoice
Invoice Dash can convert an estimate into an invoice without re-entering the same client and line items. Review the result because an estimate and a request for payment serve different purposes.
How to add a discount and check the invoice total
Invoice Dash supports discounts when preparing documents. Always check the resulting subtotal and final amount, especially when the invoice also includes tax or several line items.
How to review tax settings in Invoice Dash
Invoice Dash offers per-item, total and tax-inclusive calculation modes. These are calculation settings; choose the mode and rate that match your own verified invoicing requirements.
How to record a deposit or partial invoice payment
Invoice Dash can record more than one payment against an invoice and update its outstanding balance. Enter money actually received rather than treating a promise to pay as a completed payment.
How to create a receipt from invoice payment records
Invoice Dash can generate a receipt from recorded payments. Review the payment history first so the receipt reflects received amounts rather than only the original invoice total.
How to add a payment-link QR code to an invoice
Invoice Dash can include a payment QR code based on payment-link information. The QR code directs a client to the supplied destination; it does not process or confirm the payment itself.
How to use invoice due dates and reminders
Invoice Dash can flag overdue documents and provide optional due-date notifications. A useful reminder starts with an accurate due date and a current record of payments.
How to review income and unpaid invoices in Invoice Dash
Invoice Dash reports help you inspect recorded income, outstanding amounts and client activity over selected periods. Their usefulness depends on complete and accurate document and payment records.
How to review duplicate photos before deleting them
Cleanup Pro groups suspected duplicate photos so you can review them before deleting extras. Keep the version you actually want rather than deleting an entire group without inspection.
How to choose which similar photos to keep
Similar-photo groups can contain worthwhile differences: a sharper face, an open pair of eyes or a better moment. Use Cleanup Pro to compare, then choose deliberately.
How to clean up old screenshots on iPhone
Cleanup Pro separates screenshots so you can review saved tickets, reference images and temporary notes together. Remove obsolete captures while keeping documents you still rely on.
How to review large videos before freeing iPhone storage
Video files can occupy substantial space, making them useful candidates for review. Cleanup Pro helps you browse videos, but duration and size alone do not determine what should be deleted.
How to make photo cleanup a manageable routine
A small review session is easier to verify than a one-time deletion of thousands of photos. Use Cleanup Pro's categories to work through one kind of clutter at a time.
Why Cleanup Pro may not show all your photos
The photos visible to Cleanup Pro depend on the access granted by iOS. Limited or selected-photo access can make a scan look incomplete without anything being wrong with the library itself.
Why iPhone storage may not drop immediately after cleanup
Deleting photos does not always produce an immediate matching reduction in iPhone Storage. Recently Deleted, iCloud optimization and delayed storage calculations can all affect the figures you see.
How to look for a photo deleted during cleanup
If a photo was recently deleted, start in the Photos app's Recently Deleted collection. Apple normally keeps deleted photos and videos there for 30 days before permanent removal.
How to review duplicate contacts before merging
Cleanup Pro can help find and merge duplicate contacts. Check the names, numbers and email addresses first so two different people are not combined just because they share a name.
Should you delete contacts that have no phone number?
A contact without a phone number may still contain a useful email address, postal address or other reference. Cleanup Pro can surface these records, but missing one field does not make a contact unnecessary.
How to check photos saved in Cleanup Pro's Secret Album
Cleanup Pro includes a password-protected Secret Album for selected media. Verify saved items and understand where other copies remain before relying on the album for privacy or storage management.
How to read Cleanup Pro's system monitor without confusing RAM and storage
Cleanup Pro displays device-resource information alongside its cleaning tools. Storage and memory are different: deleting a photo can affect file storage, but it is not a promise of permanently lower RAM use.
