For the longest time, I relied on a photo to take my documents from paper to the digital world. But now that I've discovered the power of OCR scanning software, I have no intention of going back to the Paper Ages.
I most often use scanning apps for business-related documents and forms of ID, but as you'll see below, you can use these apps for almost any kind of document: books, receipts, certificates, or even a page of your own handwriting.
I've been updating this article for a few years, and after testing dozens of mobile scanning and OCR tools again this year, I've handpicked nine that will change the way you manage your documents.

Google Lens for all the Google bells and whistles
What makes the best OCR cell phone app?
If you don't own a scanner, you can still digitize documents quickly with a mobile scanning app—all of the apps on this list will do the trick. But if you need to turn your pages into a file you can edit, you'll want optical character recognition (OCR) as part of your mobile scan app. That's what will turn your mobile scans into editable digital documents.
With that in mind, the best OCR software with mobile scanning should excel in a few key areas. Not every app on this list meets all of these criteria, but if you're going to scan with your phone, these are the features you'll want to look for—and it's what I was looking for as I tested.
Auto-scanning. Every app on this list includes some kind of scanning feature, but I paid attention to which apps made the process as painless as possible. This included testing how well each app focused on the document, how accurately the sensor detected borders, and how long it took to capture a scan.
Accuracy. An OCR app needs to be accurate—no one wants to spend ages editing gibberish text, so I paid attention to how accurately each app produced digitized text from my scans.
File management. A phone scan app doesn't need to have lots of bells and whistles, but I did take into account how effective each app was at organizing, saving, sharing, printing, and exporting digitized files.
Customization. Scanning and digitizing a document may just be the beginning for you. If your goal is to add more text, a signature, or watermarks, or to password-protect your documents, having customization options is also important.
Scanning modes. You're likely going to be scanning a variety of documents—from IDs and passports to books and receipts. Having different scanning mode options can help with this kind of variety.
Bonus: AI features. Some apps are starting to incorporate capabilities like text translation, math problem-solving, or even counting to spice up the user experience.
One other thing: I didn't want bloated apps—if you just want to scan, you don't need a CRM to do it. Having said that, it's worth taking a look through your existing tech stack to see if any of your current apps already have this technology (many do).
I looked through the top-rated apps to come up with a giant list of tools to consider. After narrowing it down based on the criteria above, I did in-depth testing on all the top contenders.
How I tested the mobile OCR apps
How we evaluate and test apps
Our best apps roundups are written by humans who've spent much of their careers using, testing, and writing about software. Unless explicitly stated, we spend dozens of hours researching and testing apps, using each app as it's intended to be used and evaluating it against the criteria we set for the category. We're never paid for placement in our articles from any app or for links to any site—we value the trust readers put in us to offer authentic evaluations of the categories and apps we review. For more details on our process, read the full rundown of how we select apps to feature on the Zapier blog.
To test the performance of each app, I used three very different documents:
A certificate with various fonts
A busy receipt with varying degrees of visible text
A wordy cooking book with thick paragraphs
Note that I didn't pick documents that would be easy. With any scanning app, you'll get the best results when working with flat, single-sided, standard size pages of crisp black text in a single typeface (sans serif, ideally) arranged in paragraphs on white paper. Fading, folding, tearing, book bindings, variations in ink saturation, and other factors can trip up OCR. Life, however, rarely gives us pristine documents.
With one exception, the apps on this list all work on iOS or Android, but I tested each app on an iPhone. I used each app in the same natural light conditions against the same background, a black placemat. When available, I used any auto-scanning features in the app that were relevant to that particular text. For example, CamScanner has a special mode for scanning book pages, so I used that on the textbook, while other apps don't come with these settings and force you to do cold-turkey scans.
I went into this experiment thinking I might see subtle differences in terms of how well each app processed color or how many errors I could count among the OCR texts. And I assumed I'd end up with at least a dozen apps that I could easily recommend. That wasn't the case. When the wheat separated from the chaff, there wasn't a lot of wheat left.
While narrowing down the list, some apps didn't meet basic requirements, and others performed poorly. One app failed to scan and properly crop the standard receipt (the easy test, which most other apps passed with flying colors). Another was able to scan perfectly only to produce indiscernible, gibberish text.
In the end, only a handful of apps successfully emerged as respectable, dependable options. Here are the nine best mobile apps for scanning and OCR.

Best free OCR software
Adobe Scan
Adobe Scan pros:
Up to 25 pages for free
It automatically detects phone numbers and URLs
Adobe Scan cons:
Some accuracy hiccups
Adobe Scan offers several modes for scanning, including books, documents, business cards, ID cards, and even whiteboards. I started by scanning the receipt and was pleasantly surprised to discover that the app not only can detect phone numbers and URLs but also makes the number or URL clickable. This should be useful, especially if you're on the go and don't have time to jot down a number or website—you can just take a pic and easily access that information later.
As far as digitizing, it had some hiccups with accuracy, but not too shabby overall. The prices on the receipt—which other apps had pulled just fine—were incorrect here. On the other hand, the certificate fared a lot better, with Adobe catching most of the text except for the "Certificate" title at the top. What's interesting is that the book wound up being the most accurate: there were a handful of errors with some of the words, but for the most part, the text was correct enough to decipher.
Overall, Adobe Scan is a solid option for anyone looking for a free OCR app. It comes with basic file management and editing capabilities, which makes it edge out Microsoft Lens for a free option. And for those looking for a few more features, like the ability to export to Word, compress and combine PDFs, protect PDFs with a password, or digitize up to 100 pages, there's a premium plan available.
Adobe Scan price: Free; $9.99/month or $69.99/year for premium features.
Best OCR scanner app for iPhone users
Apple Notes
Apple Notes pros:
Very accurate
Comes free and installed with your iPhone
Apple Notes cons:
Scanning and digitizing a large section of text is difficult
Apple Notes is intended to be a note-taking app, but Apple has added OCR features that are good enough to get it a place on this list.
To scan and digitize text, click on the camera icon, and you'll see four options, including Scan Documents and Scan Text. The first option just scans the document and places it in a note, while the Scan Text option allows you to select a section of text and insert the text directly into a note.
I found the OCR to be accurate, but I'd argue it's best used for digitizing smaller chunks of text. For example, when I tried to scan any of the documents, it had some trouble finding and fitting all the text on the page within the scanning borders, so I had to approach scanning each document one section at a time. But I really appreciate how accurate the digitized text was. Editing was very minimal—only a few punctuation marks here and there.
Since this app is completely free to use for iPhone users and incredibly convenient for people who use the Notes app religiously (like me), I think it's a good one to consider if you ever need some quick OCR.
Apple Notes price: Free
Did you know you can simply take a picture of some text, go to the Photos app, and copy that text straight from the photo? If you have no need for a scan and just want the text, this is a great, very accurate option for native OCR on the iPhone.
Best OCR scanner app for a variety of features
CamScanner
CamScanner pros:
You can edit the text directly within documents
Multiple formatting options for digitized documents
Various export options, including Word, Excel, PowerPoint, or image
Additional AI-based features, like solving math and translating text
CamScanner cons:
OCR may miss spaces or punctuation
As I went through the testing process, CamScanner was the first breath of fresh air. I didn't once have to adjust the borders on any of my documents, and the level of detail was on another level. It recognized almost all the text on the certificate, including that tricky "Certificate" title that had been tripping up all the other apps. It also broke up each portion of text as separate lines, which was a nice touch.
Another pleasant surprise was how CamScanner performed with the book. When I exported a page as a Word document, it looked like an actual picture instead of just a digitized scan. The text was organized almost exactly as it was in the book, including the positioning of the paragraphs—and it was all completely highlightable.
When customizing documents, you can add a signature, but unlike on other apps, you're only able to either import the signature or have the app scan it from elsewhere. (Most other apps allowed me to simply draw my signature on the phone screen.) You can add watermarks and set a passcode to protect documents, though, and the naming suggestions when saving and managing files was a nice touch. Another helpful feature is the ability to edit digitized text—but the words I changed became bolded and distorted, and some of the original text got a little cut off.
Beyond this, CamScanner still has a ton of other customization and scanning features, including ID photo making, erasing text, scanning PowerPoint presentations and whiteboards, and even rearranging PDF pages. My two favorites were its ability to solve math problems and translate written text—both of these AI features worked great for me, even with my messy handwriting.
While the price for CamScanner may seem a bit steep, I think it's well worth it for how feature-rich it is. Not only is the OCR accurate, detailed, and optimized for the user's benefit, but with the premium subscription, you can search text within your documents, create collages, scan unlimited documents, and get 10+ GB of cloud space.
CamScanner price: $9.99/month, $69.99/year, $299 lifetime
Best OCR app for text-to-speech (and Microsoft users)
Microsoft Lens
Microsoft Lens pros:
Straightforward to use
Completely free
Microsoft Lens cons:
There's no way to create folders for file management
You can't edit digitized text within the app
Microsoft Lens is straightforward—that's what drew me in. If you give the other apps on this list a shot, you'll notice that a lot of them require you to sign up or give you a tour before you can even scan your first document. While there's nothing inherently wrong with that approach, Microsoft Lens skips all of the fuss and lets you get right to scanning.
The app used to be pretty bare-bones, only allowing you to scan, do basic editing, and export your scans. Now, there's an Actions mode: it lets you take a picture of a document, like a page or receipt, and it will generate the text for you to copy. It worked perfectly well with the book, but it refused to work on the certificate, and the receipt text came out somewhat inaccurate.
The coolest feature, though, is the new Immersive Reader mode. You can snap a photo of any text, and it'll transform it into a clean, eBook-style screen for easy reading. Plus, you can press play to have the app read it aloud to you.
Once I finished editing my documents, the app took me straight to the export options, which included either saving the document to the iPhone Photos app or other compatible apps. That said, Microsoft users will enjoy the ability to save documents and import them into other Microsoft apps, including OneDrive, OneNote, Word, and PowerPoint.
In terms of OCR, the receipt and certificate were mostly accurate, with a line or two missing. And while the book was a bit of a Final Boss for most apps, Microsoft Lens was able to step up to the challenge. It still had a few issues with accuracy—a few missing words and letters—but it was still mostly readable.
Price: Free
Best OCR app for extra features
iScanner
iScanner pros:
Intuitive interface with helpful tutorials
An abundance of extra features, such as the ability to do math or measure distances
iScanner cons:
Its most useful features, including OCR, are only available for paid users
Formatting can be a little awkward for digitized text
iScanner had my favorite interface out of all of the OCR apps. It offers a lot of features, which could have been overwhelming, but it does a great job of organizing everything. Whether you're looking to scan an ID card, sign a document, or recognize text, the app makes the features readily apparent by splitting actions into the following categories: Scan, Edit, and Share. And if you're feeling lost or curious, just click on the circular icons at the top of the screen, and you'll find video tutorials for most of the features.
As far as my standard testing documents, iScanner performed pretty well. With the certificate, it missed the title at the top by a letter (not unusual), but it was mostly accurate. The book and receipt were fairly accurate (the book a little more so), but the way the app formats the recognized text was a little wonky for these two.
But similar to CamScanner, what makes this app stand out is that it can complete other AI actions with the information it detects. For example, I handwrote a fun quadratic equation—3x
2
+5x−8=0
—and the app solved it in seconds. If you really want to see what the app is capable of, throw some more advanced algebra at it, and you should get similar results. It can also count. I scribbled nine dots on a piece of paper. After analyzing and identifying the shape of each dot, the app was able to count all nine.
Another small detail I enjoyed was the ability to blur out text on a document. Most OCR apps offer this to some extent, but iScanner sets itself apart by making the blur match the color of the background of the document, so it almost looks like you've taken out the text altogether. The AI polish feature also does a great job of cleaning up scans and making them look more readable and vibrant. Overall, iScanner is definitely one of the strongest choices on this list.
iScanner price: $9.99/month or $19.99/year
Best mobile scanning app for accuracy
Tiny Scanner
TinyScanner pros:
Great OCR accuracy
You can add watermarks to scans
Share scans directly to Google Drive, OneDrive, Box, Evernote, and Dropbox
TinyScanner cons:
You can only access OCR with a paid plan
I can confidently say that Tiny Scanner was the most accurate of any on the list. CamScanner was a close second, but it struggled a bit with misspellings and omitted words, while Tiny Scanner was correct to the T.
To access Tiny Scanner's OCR features, you'll need to subscribe to a paid plan, but there is some flexibility when it comes to simply scanning. For example, when I revisited the app after my free trial expired and tried to scan, I was hit first with the prompt to upgrade to premium. But when I clicked out of the prompt, another pop-up showed up asking me to simply watch an ad for one-time access to the feature I wanted. The videos can be as short as five seconds, and the longest one I had to watch was 20 seconds.
If you use OCR often and you're looking for an app that's going to provide consistent accuracy, the $4.99/month price tag is worth it.
Tiny Scanner price: Free plan available; premium plans are $4.99/month or $49.99/year
Scan Shot was equally as accurate as Tiny Scanner, but the app is more basic. It's a really simple app: you can scan different documents, convert text, copy and paste that text, add signatures and filters, and that's pretty much it. At $9.99/month, it's a bit pricier than Tiny Scanner and with slightly fewer features. Still, I wouldn't count it out, especially since you can use Scan Shot's OCR feature for free.
Best handwriting OCR app
Pen to Print
Pen to Print pros:
Ability to scan and digitize handwritten text
Accurate even with slightly messy handwriting
Pen to Print cons:
No folder creation
Even in the age of all-things-digital, handwriting will never fully go out of style. For those of us who enjoy the feel of putting pen to paper but also occasionally need to put those writings onto a screen, Pen to Print is a great solution for OCR handwriting recognition.
I had to go off-book to test this one, so I created a basic travel list. I began with my normal handwriting: the app had some difficulty detecting my list at first, but almost all of the items came out correct once it was digitized. In the second round, I decided to instead write a sentence in cursive. And the result was even more impressive: it got everything right.
You can save your digitized texts to the app, but if you want to export to other platforms—or copy, paste, and edit the text—you'll need to subscribe to the premium plan. The payment options are more than reasonable, though, starting at $2.99/month.
Pen to Print price: For OCR features: $2.99/month, $9.99/yr, or $29.99 one-time
Best OCR app for quick auto-scanning
Genius Scan
Genius Scan pros:
Quick and accurate auto-scans
Consistent accuracy
Clean-up features
Text search
Genius Scan cons:
No signing features within the app
I was most impressed with how Genius Scan managed to be the only app to auto-scan full pages of the book, unlike most apps on this list that would only grab sections of text or require me to manually adjust the borders. Auto-scanning the receipt and the certificate was also a breeze. I'd accidentally gotten a drop of water on the certificate, but the app automatically removed the blemish, along with the wrinkles in the paper.
The OCR accuracy across all three documents was decent, and it's nice that you can type not-so-easy-to-read text into the app's search bar and find not only the doc you're looking for but also the exact place the text is in the doc. It also comes with another unique feature: curvature protection, which helps straighten out any lines or borders after scanning your document.
One slight downside is the lack of an in-app signing feature. You have to export to Genius Sign if you need to add a signature, which feels a bit clunky, especially when other apps make this process easier. But if you don't plan on using this app for a ton of signing, this isn't too much of a hassle. Plus, for $4.99/month or $39.99/year, I think it's a decent deal, considering you get unlimited scans and above-average digitizing accuracy.
Genius Scan price: For OCR features: $4.99/month or $39.99/year
ABBYY FineReader is a fine alternative for Genius Scan. The biggest differentiator is the ability to choose between two text extraction options—plain text and format preserving. The text accuracy could be a little better, though.
Best OCR app for Google bells and whistles
Google Lens
Google Lens pros:
Built-in web search access using a scanned photo or digitized text
Built-in access to Google Translate
Google Lens cons:
No way to store digitized files or text
Google Lens becomes a mobile scanning and OCR app when you use it with other apps, like Google Photos. Choose a photo from your Google Photos library, and click the lens icon at the bottom of the screen. You'll see some white dots flash across the screen as Google Lens analyzes the image, and within a few seconds, it will highlight all your text. Or you could scan something with Google Lens and then copy it to Google Docs—Google's video of this process is pretty snazzy. (Side note: you can also turn images into text with Google Drive and Google Docs.)
From there, there are a wealth of options available, thanks to Google being Google. For example, when I clicked translate, the app immediately identified that my text was English and prompted me to open Google Translate. And with the text-to-speech feature, I had a paragraph from my book read aloud to me with surprisingly strong accuracy. I even took that travel list with the messy handwriting that I used to test Pen to Print, and Google Lens had no issues identifying the words.
But Google Lens's abilities go even further: it offers "visual matches," which means that it can analyze an image or document and find similar results across the web (like Google image search). When I tested it with the certificate and travel list, results upon results of certificates and travel lists popped up. On that same note, when I clicked on the shopping tab, I was able to see results for certificates on sale, along with pricing. Thanks, Google!
While Google Lens doesn't technically have a scanning component (i.e., it doesn't store your scans), you'll find that it's not actually necessary if your goal is to extract text. You can simply take a picture of your document, let Google Lens do its thing, copy the text, and paste it elsewhere. It may not work for storing digitized versions of documents, especially for professional purposes, but it's a very convenient option to have on hand.
Google Lens price: Free
Text Fairy is a solid Google Lens alternative for Android for anyone who wants to digitize text in various languages (it has over 110 languages in its database). Like Google Lens, it also has a text-to-speech feature.
How do I scan with my phone?
All the apps here will scan text and—either natively or by copying it elsewhere—let you edit that text however you want. It's honestly kind of incredible. Even more impressive is that your phone has some of these features built in.
If you have an iPhone or iPad, just take a picture or screenshot with some text, and you'll see a little button pop up that lets you highlight, copy, and paste it. I used this feature regularly, and I've found it to be extremely accurate and adept at capturing even the vaguest text. You may have to do some maneuvering with the formatting—there will be some awkward line breaks if you're copying paragraphs, for example—but it's ridiculously convenient.
