5 stars: Super useful!!! I don't have a scanner, and I've used this app for years, and even for government documents, and I never had any issues whatsoever! And I like the options, especially the various filters after you scan a document, sometimes they're super useful. I definitely, absolutely do suggest it, and already have suggested it to other people IRL too. Very happy with it!
4 stars: So much easier than trying to use my printer/scanner. The only thing is, when im dcanning books with dark images, its incredibly hard to see. Also its hard to see the words when i scan the pages because the words bend where the spine of the book is. I wish there was a way to straighten the scan to make the pdfs more readable.
4 stars: It's a great option for scanning and sending documents. One thing that would make it even better is if the crop option was better. It's some times hard to get the corners where you want. Instead of having just the drag option it would be nice if you could select a corner and tap up/down left/right to move it slightly and get it to exactly where you want.
3 stars: This app is free, which is great. It's just noticeably not as good as CamScanner. The border/corner detection is slower and not nearly as precise, and there aren't as many colour processing options. There also aren't as many export options like saving scans as an image. Still a decent app and pretty good for a totally free option; it's just hard to go from CamScanner to this.
