Built only from these 120 real reviews (foreign ones translated). Superscripts jump to the quote here. Apple has no per-review links, so [ref] opens that app's reviews on the App Store.

  1. [R1] Scanner Pro・Scan PDF Documents 1/5 · US “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.
  2. [R2] Scanner Pro・Scan PDF Documents 5/5 · US 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.
  3. [R7] Scanner Pro・Scan PDF Documents 1/5 · US 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
  4. [R8] Scanner Pro・Scan PDF Documents 5/5 · US 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.
  5. [R18] Scanner Pro・Scan PDF Documents 3/5 · GB 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
  6. [R22] Scanner Pro・Scan PDF Documents 2/5 · US 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
  7. [R23] Scanner Pro・Scan PDF Documents 5/5 · US So simple: Love the scanner so easy!
  8. [R27] Scanner Pro・Scan PDF Documents 3/5 · GB 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
  9. [R3] Scanner Pro・Scan PDF Documents 3/5 · US 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.
  10. [R5] Scanner Pro・Scan PDF Documents 5/5 · US Great tool!: I’ve been using Scanner Pro for years. It’s an excellent tool. Never any issues.
  11. [R6] Scanner Pro・Scan PDF Documents 3/5 · US 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.
  12. [R10] Scanner Pro・Scan PDF Documents 1/5 · US 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.
  13. [R13] Scanner Pro・Scan PDF Documents 1/5 · US 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
  14. [R25] Scanner Pro・Scan PDF Documents 1/5 · US 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,
  15. [R28] Scanner Pro・Scan PDF Documents 1/5 · US 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.
  16. [R24] Scanner Pro・Scan PDF Documents 3/5 · GB Support is non existent: Scanner newly starting to crash after 10 pages. So I’m scanning as I have done on this fantastic app, the documents are always 15 pages long. After years of doing this in one go, now the screen goes black on page 10, then duplicates a page and after a screen tap and a shake I can resume. It cause extra pages to be printed every time and longer documents than necessary as
  17. [R56] Scanner Pro・Scan PDF Documents 1/5 · US 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!
  18. [R58] Scanner Pro・Scan PDF Documents 1/5 · US 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
  19. [R60] Scanner Pro・Scan PDF Documents 2/5 · GB Crashes permanently: It was a great app back in the days. I used it since 2016. Since 2024 it started to crash and glitch again and again every single time I tried to use it. I have send hundreds of technical reports generated by the same app to support team. Nothing has changed and no one contacted me back. In my opinion this is the best way to start showing your customers you don’t need them any
  20. [R37] Scanner Pro・Scan PDF Documents 1/5 · US 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.
  21. [R43] Scanner Pro・Scan PDF Documents 1/5 · US Watermark is intrusive: Only decent if you pay
  22. [R46] Scanner Pro・Scan PDF Documents 1/5 · US 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.
  23. [R48] Scanner Pro・Scan PDF Documents 2/5 · US 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.
  24. [R61] iScanner 1/5 · US Don’t use this: You need to pay to be able to use it and it’s impossible to cancel your subscription.
  25. [R63] iScanner 3/5 · US Is it really worth the $12/week?: Don’t get me wrong - this app is leagues better for photoscanning than any other app I’ve tried. The colors are vibrant, and the images are nice and aligned. My only gripes are that it doesn’t tell you about the price until you try to share your scan, and that the price is twelve dollars per week (after the one week free trial). It can only reasonably be said to b
  26. [R67] iScanner 1/5 · US UScamer: They think we are stupid, idiotic, weekly SUBscription; leave it
  27. [R76] iScanner 2/5 · US Not free to save a pdf scan: It's free to download the app, free to scan a document, but you can't do anything with the document once you scan it, can't even save it. So, not a free option to obtain a usable a PDF scan document.
  28. [R16] Scanner Pro・Scan PDF Documents 1/5 · US 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.
