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)

This isn't free, I didn't see anything stating there was a $60.00 a year subscription fee, then I recieved an email from google saying my 7 day free trial was done and had already removed money from my account, I clicked manage my subscriptions and it was already set up as a subscription i canceled the subscription right away but some how they're able to keep my money. This whole subscribing for a fee for basic apps is pretty messed up enough, deceptive "sales" practices is another level

I paid for this product and it is full of glitches and kicks me out half way through an edit, deleted my document and I have to start all over again. Highly annoyed and want my money back, this is a terrible app for editing. Viewing fine, editing, good luck.
