This used to work great, but something changed with the most recent update resulting in the app no longer taking pictures. Pressing the button to take a picture and scan a document does not do anything, it just seems to ignore the on-screen button press. The document edges are detected and outlined on the screen, but the app is no longer capturing the image to a saved file. Update: It's now working again since the last update. Update 2: It is now 6 out of 5 stars.

I am sorry about the issue. It has been fixed already. Hope to deserve the 5 stars from you one day!

Such a terrible app. Often won't recognize document and when it does, can't scan multiple pages and when you try to merge the separate scans into one PDF document, it does it in the reverse order, with the last page first, with no option to reorder it! And it struggles to scan pages with one paragraph of content on it. All that labour only for me to discard it and start again after finding a better app. Sigh.

This app is very fantastic. The performance of app is excellent. I am not a developer but I want to give my suggestion to look it's interface look morden and convenient. please add Id card scanning , QR code scanning and document print feature. Keep the app functions in the front page as app interface categorically like camera scan, photo from gallery, document from phone, I'd card scan, book scan ,pdf compress, OCR, single scan, batch scan, print or whatever functions comes in future.
