I downloaded this app to scan a very important document which was several pages in length. I was able to take pictures of each page using the app, but when it took me to the cropping screen, the app would close out of the screen and delete all of my progress about halfway through cropping. This happened at least four times. However, I was able to make it through the process one of the first times I tried and generated a PDF of decent quality (though its file size was too large for what I needed)
