  1. [R3] 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
  2. [R5] iScanner 5/5 · US Easy Peasy: I just took my pictures (scanned) and they were complied into a PDF!! Thank you for making a complex process “easy peasy!”.
  3. [R6] iScanner 3/5 · GB Faint scan when using the camera: The scan is very user friendly but the images are faint
  4. [R13] iScanner 1/5 · US Convert to text: When I tried to convert my hand writing to text it didn’t do it the way it was written. Instead it reorganized the words, and erased a lot of the hand writing.
  5. [R9] iScanner 3/5 · GB Scanning documents: It’s a shame you can’t name and save the documents, rather then forwarding them on first. Or if you can, I can’t see how
  6. [R12] iScanner 3/5 · GB Slow and not very intuitive: Very average
  7. [R23] iScanner 5/5 · US Awesome App: It’s very simple to use and produce great documents
  8. [R2] iScanner 5/5 · US Very useful: I have used the app for years and I am very happy with it.
  9. [R4] iScanner 1/5 · US Horrible: Don’t use. Since the new update it’s extremely slow and not worth the effort.
  10. [R14] iScanner 5/5 · US Great App: Works like a charm! Great quality scans. Very easy to use and very versatile!
  11. [R1] 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.
  12. [R7] iScanner 1/5 · US UScamer: They think we are stupid, idiotic, weekly SUBscription; leave it
  13. [R16] 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.
  14. [R10] iScanner 1/5 · US Unhappy: I would like a refund because it is very difficult to turn text messages into a document, as that’s what I wanted to do. You have to access every text, and take a screenshot. I really wish there would have been a free trial.
  15. [R52] iScanner 1/5 · GB Makes the cancel button for the pro trial absurdly hard to find: Clearly just trying to trick people into paying for another subscription, the lack of integrity from apple is to be expected but still very poor.
  16. [R58] iScanner 1/5 · GB Terrible app!: Will not allow me to cancel my subscription! Keeps throwing out a message no internet connection though I have connection 😡
  17. [R22] iScanner 1/5 · US ads suck: Dude this sucks. The ads are so intrusive and have fake buttons so you click on them. The scanning is whatever and it’s so many steps to just send myself an email and multiple scans under one batch is under a paywall. You’re a glorified camera app. Get over yourself (I’m mostly salty about ads. They are truly the worst)
  18. [R70] 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.
  19. [R97] 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.
  20. [R106] 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.
  21. [R108] 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.
  22. [R28] iScanner 1/5 · US Not sending my emails: Normally I would rate this a 5, because I have loved it. Until the last few days. I'm frustrated because I've tried to send some scanned docs to my other email & it's not working. I've tried this 6-7 times on different days hoping it was a glitch. It says it was sent, but never arrives. Please Help!
  23. [R60] iScanner 1/5 · GB Confused by the high ratings: I am genuinely confused and unsure how people have rated this so high - either they haven't used any other scanning App or they are fake. Slow and absolutely rubbish - the results are damn awful - processing is awful - i was stupid enough to get yearly premium without really trying in - now it's just sat there - can't even get the money back.
  24. [R78] 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
  25. [R90] Scanner Pro・Scan PDF Documents 3/5 · GB Good scanning, but subscription prompts have become intrusive.: I have always been a strong proponent of this App, even as storage Apps such as OneDrove have caught up with native scanning features. OCR is very good and I’ve not had major issues with border detection that others have mentioned. I am, however, getting fed up with the subscription ads and prompts.
