Best Scanner Apps for iPhone & Android (2026): Free and Paid

Almost every scanner app can take a clean photo of a page. The difference is what happens next: watermarks you didn't expect, a subscription for basic features, and a growing pile of files called Scan_20260714.pdf that nobody can find.

The short answer: the best scanner app for most people on iPhone and Android is Filex AI. It scans without watermarks, reads every page with OCR, names and files each scan from what it says, reminds you about dates inside, and downloads any scan as a PDF. If you only need a quick free scan now and then, the Notes app on iPhone or Google Drive on Android will do.

Quick comparison

Prices change often and vary by country, so check the App Store or Google Play for the current price before you subscribe.

Microsoft Lens used to be on every list like this. Microsoft retired it in 2026: it left the app stores in February and stopped scanning on March 9, 2026. If you used it, see our Microsoft Lens alternative guide.

Scanner app vs scanner that organizes

A scanner app turns paper into a PDF or image: it finds the edges, flattens the page and cleans up the contrast. Every app on this list does that well.

An organizing scanner keeps going after the photo. It reads the text, works out what the document is, names the file, puts it in the right folder and remembers the dates inside, so a scan you made in March is easy to find in December.

Most people looking for a "better scanner app" don't actually have a scanning problem. They have a finding problem. That's why Filex AI is our top pick.

How we compared them

• Scan quality: edge detection, perspective correction, multi-page scanning, curved pages
• Price and limits: free features, watermarks, ads, subscriptions
• Text recognition (OCR): included free, paid, or missing
• Output: PDF, image, cloud export
• Organizing: does the app name, file and remind you, or leave it all to you?

Before you choose: test these 4 things

Any scanner app can look good in screenshots. Try these with your own documents in the first few minutes:

1. A crumpled receipt. Does it find the edges and flatten the paper, or do you have to crop by hand?
2. A 3-page document. Can you scan all pages into one file in one go?
3. Search for a word you scanned. Search for the store name on the receipt. If nothing comes up, the app isn't reading your scans (no OCR, or OCR only in a paid plan).
4. Find it again tomorrow. Close the app, come back the next day and try to find the receipt without scrolling. This is where most scanner apps fail, and where an organizing scanner pays off.

1. Filex AI: best scanner app overall

Filex AI is a scanner and a filing system in one app.

What it does:

• Scans without watermarks, on iPhone and Android.
• Reads every scan with OCR, including handwriting (print or cursive).
• Names each scan from what it says. Scanned Document 4 becomes PGE_Electricity_Bill_Sep_2026.
• Files it automatically into folders like Money, Home, Health and IDs, following your own rules if you set them.
• Reminds you before dates pass: renewals, due dates and expiry dates found inside your scans.
• Finds any scan by what it says. Search "Costco receipt" or ask "when does my car insurance renew?".
• Downloads any scan as a PDF, and can turn a PDF into images when a form needs JPGs.
• Lenses group scans by topic ("tax season", "Mom's medical records") without copying them.
• Works with your other files too: PDFs from email, screenshots and documents shared from any app join the same library, on iPhone, Android and the web.

Price: your first 10 files are free; Pro is $7.99 a month for 500 files or $44.99 a year.

Best for: anyone who scans bills, receipts, IDs, contracts or school forms and wants to find them again without filing by hand.

2. Adobe Scan: best for clean PDFs

Adobe Scan is a free scanner from the makers of Acrobat.

Strengths:

• Free, with strong edge detection and cleanup
• Text recognition, so scanned PDFs can be searched and copied
• Works with Adobe Acrobat and Adobe's cloud storage

Limits: needs an Adobe account, and extra features sit in paid Acrobat plans. You still name and file every scan yourself. See Adobe Scan alternative.

Best for: people already using Acrobat.

3. Genius Scan: best simple, ad-free scanner

Genius Scan has been a favorite for years because it's quick and uncluttered.

Strengths:

• Free basic version with scanning, editing and export, and no ads
• Good batch scanning and page cleanup
• Paid Ultra plan adds text recognition, searchable PDFs, more export options and cloud sync

Limits: text recognition isn't in the free version, and organizing is manual. See Genius Scan vs Filex AI.

Best for: people who want a simple, no-fuss scanner.

4. CamScanner: best for PDF tools

CamScanner is one of the most downloaded scanner apps, with lots of extra PDF tools.

Strengths:

• Strong capture and image enhancement

5. Apple Notes and Files: best free option on iPhone

Your iPhone already has a good scanner built into the Notes and Files apps.

Strengths:

• Free, no ads, no account

• Saves as PDF

Limits: Notes keeps scans inside notes; Files saves them as "Scanned Document" in whatever folder you're in. No automatic naming, filing or reminders. Step-by-step: how to scan documents on iPhone.

6. Google Drive: best free option on Android

The Google Drive app has a scanner on Android and iPhone: tap +, then Scan.

Strengths:

• Free, saves PDFs straight into Drive

7. Scanner Pro: best for iPhone power users

Scanner Pro by Readdle is a polished iPhone and iPad scanner.

Strengths:

• Fast, accurate scanning with good cleanup

8. vFlat Scan: best for books and notebooks

vFlat Scan is built for scanning bound pages, like books, notebooks and thick binders.

Strengths:

• Flattens curved book pages automatically
• Captures both pages of an open book at once and splits them
• Auto-capture as you turn pages
• Free text recognition, with export to PDF, JPG or text

Limits: it's built for capturing pages, not for organizing everyday paperwork; naming and filing are manual.

Which scanner app should you choose?

• You want scans named, filed and easy to find: Filex AI.
• You scan once in a while and send it straight away: Notes on iPhone, Google Drive on Android.
• You live in Adobe Acrobat: Adobe Scan.
• You want a minimal, ad-free scanner: Genius Scan.
• You're scanning books or notebooks: vFlat Scan.
• You used Microsoft Lens: switch to Filex AI; Lens no longer scans.

For most people, the answer is Filex AI: it scans as well as the rest and then does the filing for you.

Is it safe to scan personal documents with an app?

Scans often include IDs, bank statements and medical records, so check three things: whether files are encrypted, who processes them, and whether you can delete everything.

Filex AI encrypts files in transit and at rest, does not sell your data, and lets you delete files at any time. See our privacy policy.

Conclusion

Every app here can scan a page. Only one makes sure you can find it again. Filex AI reads, names and files every scan, reminds you before anything expires, and gives you a PDF whenever someone asks for one, on iPhone and Android. Your first 10 files are free.
