Who it's for
Scanner Pro is for users who need a basic, ad-free document scanner for occasional use and are willing to pay for a subscription to avoid watermarks and access full features R1. It might still appeal to long-time users who have not encountered the recent issues or who find its core scanning functionality reliable R4R8. However, users who require advanced markup, reliable cloud sync, or who are sensitive to subscription models and AI-driven auto-corrections should skip this app R9R63R94R121.
Evidence note: The recent reviews skew heavily negative, particularly regarding the subscription model, performance issues, and AI features. This contrasts sharply with the high lifetime rating, indicating a significant negative trajectory in user sentiment following recent updates. The developer's release notes for the latest update focus on 'smarter printing' and 'paper size detection,' which directly contradicts many user complaints about inaccurate auto-detection and the removal of manual size selection.

- [R4] Solid App: I've been using this app for over 10 years and it's been amazing for me. I really enjoy the auto capture figure of the document scanner and the ability to send the photos through various emails.
- [R6] One of the best apps ever gotten!!: Great and efficient and comes in handy a lot of times. Hope it keeps on going. Scanner pro is the bomb!
- [R13] Excellent Scanner: This is a great scanner with faxing capabilities as well as the ability to share it via email, etc. Highly recommend
- [R15] The Best: This app far exceeds any other scanner app that I have used previously.
- [R1] Nice scanner, No ads.: The add that the other apps automatically place on any document you scan unless you pay is not nice, I like how it has no ads on the document when I share it.
- [R7] Great App: Great scanner app with faxing ability.
- [R8] So helpful: I’ve had scanner pro for several year now and I can’t express how much helpful it is to scan on the spot, keep my important information on the fly, transfer pdf to photos.
- [R28] Old friend: Still my favorite scanner. Receipts, official documents, sheet music for my side people & photos for my genealogy all get nicely scanned. And re-reviewing my fave scanning app. Still my best way to create PDFs of music I’m performing!
- [R38] Great app!!: I use this app daily for many documents. The workflows save a lot of time and I highly recommend it!
- [R41] I love this scanner app!: I have loved this scanner app ever since a college professor who was also the parent of a teenage client pointed it out to me and showed me how to use it. In the last year or so, this app has given me the ability to scan in books that my students read from the hardcopies so that read them online without having to hover over their shoulder all the time. And when I have cli
- [R31] Keeps crashing: I’ve been using this app for years. It’s been very reliable so far, but it keeps crashing since the latest upgrade. Very frustrating.
- [R30] Frequent crashes: This App crashes all the time in the middle of a simple two-document capture. I’ve used it for years with great success, but in the last 6-months it’s been awful.
- [R35] Latest update crashed: After it asked about some AI slop page detection it started crashing a few seconds after opening.
- [R140] Junk: I have had nothing but issues with the app crashing and unable to scan. They have zero support for this. Waste of my money!
- [R2] “update” took away the ability to preselect doc size: The app worked fine until the developer decided to force auto select page size on all scans. Silly “update” causes me to have to adjust size of every single page manually because their stupid AI thought the page is legal size while it’s actually A5. I’ll delete the app and download something else that uses common sense.
- [R9] Ruined perfect app with AI: This app used to be perfection. AI has ruined it. My default page size setting for ALL documents was letter. I want 99% of what I scan to be letter. Their new AI now sets the size to what it think it is. If I scan 15 pages and it makes them ledger, I have to change every page, doubling my workload. This happens even if I turn off the AI. They have removed the default pa
- [R879] Pru: I thought earlier version was better, it doesn’t seem to scan and crop to exact paper size now and I have to adjust every scan to photo or it looks really odd. The default is odd.
- [R14] Watermark. Useless app: I used to use this app all the time. It WAS great for easy scanning. But now it’s behind a paywall if you don’t want to submit all your assignments with an embarrassing watermark. Come on guys. Really? You could have put ads on it and it would have been fine.
- [R94] No free export: Being able to export without a watermark is not a premium feature. These are the table stakes. If I can’t do that the app is useless. I am not letting you extort me for basic functionality.
- [R104] Watermark is intrusive: Only decent if you pay
- [R115] Free version is useless now: This app used to be great. It scans well and the free version had a small watermark at the bottom of each page that didn’t interfere with being able to see the pages. Now there are tons of watermarks covering every single page, so it is completely worthless to download this app unless you want to pay for the premium version.
- [R5] Subscription and AI: Stop pushing them on my face.
- [R19] Subscription pricing on that are not listed in the App Store: I have found that I was being charged two separate subscriptions however I was led to believe based on information listed the certain tools were included that one of the subscriptions was supposed to be included with Scanner Pro plus that I was being charged for the Scanner Pro plus $7.99 a week in Scanner Pro expense report for and $$4
- [R63] No matter how much you pay they want more: I’ve purchased every product this company ever put out. Then they went to a subscription model and stopped supporting the lifetime licenses they had previously sold. Even then, I understood and would subscribe to app during times I was using the app to do more than take a picture of a document and name it. So long as I had the original core functionality,
- [R75] Bought and now have to buy again.: I purchased this app several years ago and have loved it but now I have to buy an annual subscription. I thought paying for the app in the beginning was good enough, but they decided they needed to continue monetizing it so now it’s a subscription model.
- [R130] Deleted all scans with app update: Don't update. I updated the app and it blew out my entire library and no way to restore
- [R135] What happened to auto sync: This app had been working great for so many years. Now I can’t get it to sync with Dropbox or Google Drive.
- [R471] Documents lost: Do not trust this app with your documents. I had used it to scan several documents over several months. I just scanned in a document, hit save, and my entire documents were spontaneously wiped and it reset back to the “scan your first document” screen. I’ve lost documents with their other apps too. As much as I like the UI of Readdle apps, I’ve lost documents, documents have failed
- [R480] Great app but very buggy: I’ve used this app for years and have nearly 12,000 scans in the cloud. But man in the last 3 months it bugs out. It randomly disconnects its self from iCloud and turns off cloud sync. Takes ages to load and will randomly crash
- [R48] Clean Lens: Constant issues with the app telling me to clean the lens, even after cleaning it. Not sure what they changed recently, but it is frustrating.
- [R89] Camera not working with app: I used to love this app, but I’m no longer to take pictures within the app of my receipts. If they fix this then I would give them 5 stars.
- [R194] Do you respond to support emails- No: Had you for some 4 years now, reconsidering my subscription. Don’t get too big and arrogant to stop responding to support requests for paid members. Your “Clean Camera Lens” error is a false positive. It’s acting like a focusing error rather than a lens impairment, as it finally resolves itself and does a quality scan. Having it pop up repeatedly is very anno
- [R214] Broken: Tries to take trapezoidal twisted pictures of pages that amount yo two triangles of the page instead of just allowing you to take photos, much worse than just using the camera on the phone
- [R61] They keep adding extra steps to getting things done.: It now takes twice as many clicks to get things done as it once did. The pathetic designers thinks wasting time with convoluted paths to get work done makes their product better. As I've said before, I will not renew my subscription b/c they just keep adding useless steps to make people think they're improving the app. My iPhone can do the same
- [R190] The newest version is slow and crashes non stop: Please fix this as soon as you can. The app crashes all the time, and the interface is less intuitive than before. Far less so. I can’t even find or touch the buttons designed to take me to editing, etc. They are too high on the page, under the iPad window banner, so it is hit or miss. I am now really slow in competing tasks. I am wondering if this
- [R254] Search is broken on iOS 18: This has been the best scanner on the App Store for a decade, but not anymore. Its scanning ability is the same as ever, with excellent OCR for every scan. But the new UI introduced this year is terribly slow. I don't think it's a native iOS app anymore. What's worse, if you try to open a document from a search everything will blink, and it might take a dozen taps to
- [R294] REVISED REVIEW … from originally ‘Really impressed!’ to ‘DOWNHEARTED’: REVISED REVIEW: Something has changed. The automatic facility doesn’t seem to work anymore. The scanner used to select, focus, scan…. allowing me to turn a page in a book, or place a new document. Now, there’s an option to scan two pages of a book simultaneously… requiring an enormous feat for two-handed bipeds.. but a piec
- [R50] Nested Folder Orientation: Lacks the ability to create nested folders for better organization
- [R223] Lacks Good Markup: Great App overall, but I rely on Markup on documents to manage my business. Scanner Pro limits you one (1) Markup. Just one. If you need to add a Markup on a different page of your document, you have to Erase your previous Markup. And NO, I don't want to have to buy/use a different App to Markup the document I just added to Scanner Pro.
- [R246] Subscription Options: Doesn’t allow you to view subscription options, thus requiring a $7.99 per week payment after free trial ends.
- [R163] Scanner Pro? More like Scanner Amateur: You can NOT manually adjust the borders of a scan. No matter where you put the borders, scanner pro adjusts/corrects to their choice. Good system for amateurs only. I do NOT recommend this as it exists.
- [R245] bring back manual focus and set borders: new Feb 5 2026 update is terrible. too automated. bring back option to focus during shot and set borders manually when in **manual** mode
- [R122] Changes to Monthly Unethical: I bought this app when it first came out, and had access to everything. A couple days ago, I was able to mark up a document. Now it’s behind a paywall. I shouldn’t have to pay for a feature I paid for when I purchased the app.
- [R149] Bought Pro, Got Nothing: The moment this app was released, I purchased it because it seemed genuinely useful and promising. I paid for the Pro version in full. After recent updates, the app has effectively stripped me of access to what I already paid for and now aggressively pushes a monthly subscription instead. The “restore purchase” function is completely broken and does absolutely nothing. Cus
- [R11] So simple: Love the scanner so easy!
- [R16] Super easy and fast: I love how I don't need to fuss with a printer to send a quick document. Love it! Thank you!
- [R21] Kudos: I love the scanner pro. It is very convenient!
- [R121] The free version is no longer useful: I don’t use it often, so I don’t want to pay their high price. Just recently they added an obnoxious watermark ALL OVER THE DOCUMENT which can only be removed by paying. A watermark in the margin is OK; obscuring the text is NOT. Unless they change this soon, I will be finding another app to use.
- [R206] Issues sending faxes: The most recent times I’ve needed to send faxes it doesn’t work right away. It takes multiple attempts to resend the faxes before it goes through. I’m currently try to resend another fax and it keeps saying g “fax service is currently unavailable. Please try again later”
