Great start. The OCR feature works very well and saves time, as well as the auto upload to Drive and background scanning of Gallery photos features. However, I keep getting an error stating "Waiting for Wifi to upload documents" even though I have the app set to upload on any network. The app also needs some battery optimization as it causes significant heating and battery usage when combing multiple scans; which is to be expected. Overall very impressive, keep up the great work dev team! 👏🏻

This is actually a decent scanner app for documents and saving, including receipts. Just how easy it is to learn and use, give 5 stars. Lost 1 star because I have hit a couple bumps of uploading receipts and taking a picture of one. There are 3 different incidences of where I had to retake the picture of the receipt. One time I had to retake a receipt 3 times. But this is not huge, so as I use the app longer, use all the features and do not encounter further issues, I'll be back to give 5 stars.

So far I truly adore this app and it's functionality. The only thing I either can't figure out or It doesn't allow you to do, is go back into a saved scanned document later to either recrop, rotate or readjust the color. This is the only feature that really sucks about this app, especially if you just got done scanning a large amount of pages for 1 pdf you name it and save it then you realize the color needs adjusting or cropped/rotated and it won't let you do anything but rescan it all, sucks.
