Best Number Scanner Apps for iPhone and Android

Disclosure before anything else: SwipeScan, one of the apps in the table below, is ours. It sits in that table on exactly the same terms as everything else, including the two rows that read worst in the whole comparison — zero ratings and one language. Where a competitor is better, this article says the competitor is better, and in several places it does.

Now the finding that shaped the piece.

The category you are searching for does not exist

On 6 September 2026 we ran the App Store search API across the phrases a person actually types: scan phone number from photo, number scanner ocr, extract numbers from image. Every one of them returned the same set of apps, and they were all document scanners — CamScanner, Adobe Scan, iScanner, Genius Scan, Tiny Scanner. Software built to turn a sheet of paper into a PDF.

There is no dedicated “grab one number off a screen” app in those results. Not a badly-rated one, not a niche one. The slot is empty.

That is not an insult to the scanners. They are good at their job, and their job is the whole page: detect the paper, correct the perspective, drop shadows, produce a searchable file. A number grabber has the opposite goal — throw away the page and keep six characters. Being excellent at the first thing does not make an app good at the second, and the App Store gives you no way to tell them apart.

Try the thing you already own first

On iPhone, Live Text. Free, built in since iOS 15, works in Photos, Camera, Quick Look and Safari. Apple’s feature availability page lists 46 language and regional variants for it. Press and hold on the number, drag the handles, copy.

On Android, Google Lens does the same and is built into Google Photos and the Google app. On the roughly 100 device models with system-level support, Circle to Search reaches it without opening anything.

For an ordinary printed number in decent light, these are the answer. They are faster than installing anything, they cost nothing, and the accuracy is good. If that is your situation, stop reading — you have the tool.

Three things they do not do. They return a text selection rather than a number, so you get the label, the currency symbol and the line break along with the digits. They give you no control over the character set, so a 0 can come back as an O with nothing to stop it. And they have no idea whether the fifteen digits they just handed you form a valid IMEI or a typo — that gap is covered in why OCR gets numbers wrong.

What actually matters when the target is one number

Five criteria, and only two of them appear on any App Store page:

1. Digits-only output. Can the engine be told to expect numbers, so it cannot return a letter at all?
2. Region selection. Can you point at one number in a busy image, or does it read everything?
3. Check-digit verification. Does anything tell you the read is impossible?
4. Size. How much storage for the privilege.
5. What the free tier is. Every app in this set is free to download with in-app purchases.

The comparison

Every figure here comes from the iTunes Lookup API, US storefront, pulled 6 September 2026. “OCR claimed” means the developer’s own App Store description uses the words OCR or text recognition — it is what they say, not a benchmark we ran. “UI langs” is the number of interface localisations, which is not the same as the number of languages the recognition engine reads; almost none of these apps publishes the second figure.

App	Rating	Ratings	Size	UI langs	Price	OCR claimed
CamScanner	4.8	1,887,008	367 MB	57	Free + IAP	Yes
Adobe Scan	4.9	1,586,323	396 MB	19	Free + IAP	Yes
iScanner	4.8	1,399,361	298 MB	21	Free + IAP	Yes
Genius Scan	4.9	1,358,973	97 MB	20	Free + IAP	Yes
TurboScan Pro	4.9	296,099	10 MB	10	$14.99	No
Scanner (Luni)	4.7	222,163	164 MB	20	Free + IAP	Yes
Tiny Scanner	4.8	181,554	179 MB	16	Free + IAP	Yes
TurboScan	4.9	101,971	10 MB	10	Free + IAP	No
Photomyne	4.7	95,161	227 MB	16	Free + IAP	No
ScanGuru	4.6	93,043	46 MB	14	Free + IAP	Yes
SwipeScan (ours)	—	0	104 MB	1	Free + IAP	Yes

Read the ratings column first and ours is the worst entry on the page. Zero ratings means nobody outside the developer has vetted it. One language means English only, against fifty-seven for CamScanner. Those are real disadvantages and no amount of feature talk cancels them.

Read the size column and something else falls out. Adobe Scan is 396 MB. That is four hundred megabytes of app to read fifteen digits off a SIM tray — justified if you scan contracts weekly, absurd if you needed one number once.

The most interesting row is TurboScan. Rated 4.9 across almost 400,000 people between its two listings, 10 MB, no data collection, all processing on device. And its App Store description does not contain the word OCR anywhere. It is an outstanding image-to-PDF scanner that will not give you the number as text. If someone recommends it for number scanning, they have not read the listing.

Photomyne is the same shape of mismatch: 4.7 from 95,161 people, and it digitises printed photographs. There is no text extraction in the description at all.

Not one of them verifies the number

Search all fifteen App Store descriptions we pulled for checksum, check digit, Luhn or validate. Zero hits. Not one app in this category — ours included — tells you when the number it just produced cannot be real.

This is the gap that costs people time. An IMEI’s last digit is a Luhn checksum and a VIN’s ninth character is a mod-11 check digit, so both can be tested in a millisecond, and a failed test converts a silent misread into a visible error. Every app in that table hands you digits and lets you find out later.

Our app does not do it either. The number extraction tool on this site does the constraint half — it restricts the recognition engine to a digit alphabet before it starts, so an O cannot come back where a 0 belongs — and the identifier-specific pages run the actual checksum. That is a browser tool rather than an app, so it has no scan history, no batch mode and no offline use, and it downloads a recognition engine on first use.

If you want the words around the numbers as well, the general category is a different shortlist — the free OCR apps worth having on each platform.

What to install, honestly

• Printed number, iPhone, good light. Nothing. Live Text.
• Same on Android. Nothing. Google Lens.
• You already scan documents. Whichever of CamScanner, Adobe Scan, iScanner or Genius Scan you have. All four claim OCR, all four are rated 4.8 or higher across more than a million people, and the marginal benefit of switching is close to zero. Genius Scan is the smallest of them at 97 MB.
• You want small and private and do not need text. TurboScan, 10 MB, no data collection. Free version first — the $14.99 Pro listing is the same app with a different purchase model.
• Numbers into a spreadsheet. Different problem with its own traps, covered in extracting numbers from an image to Excel — the 15-digit precision limit will eat a long identifier before you notice.
• A list of phone numbers. Pulling phone numbers out of a photo covers the format rules that catch misreads.
• Repeatedly grabbing single numbers off screens. The digits-only extraction tool in a browser tab, or SwipeScan for the camera and the swipe selection — with the zero-ratings caveat above stated plainly.

The short version

• Search the App Store for a number scanner and you get PDF scanners. The dedicated category is genuinely empty, not merely crowded.
• Live Text and Google Lens are free, already installed, and Apple lists 46 locales for Live Text. For ordinary printed digits they win, and no app in the table beats them enough to justify the download.
• Size varies by a factor of nearly forty across apps doing broadly the same job — 10 MB for TurboScan, 396 MB for Adobe Scan.
• TurboScan and Photomyne have excellent ratings and no OCR claim in their listings. Ratings do not tell you what an app does.
• None of the fifteen apps verifies a check digit, ours included. That is the part still worth doing yourself.
