I really like Stack, super convenient, and the backup is pretty handy, though I'll say I would like a couple of features: 1) enable backups at the stack level, not an all or nothing. There will inevitably be some things I don't want to entrust to the security of the cloud. 2) when uploading, create folders for the different document stacks. that way, if I share the location in Drive, any new documents will be added to those shared locations automatically.

The concept for this app is simple and brilliant. Organize your important paperwork easily and make it accessible on your phone. I use it all the time for bringing up my insurance, my passport, my vaccination records, all kinds of stuff. With that said, this app needs more investment for sure. It needs a smarter AI for document classification. It needs a more streamlined interface for sorting through suggested documents. It shouldn't be multiple screens to dismiss something etc.

One of the best mobile pdf scanners. Keep in mind that you need a Google account in order to use this but if you do it can conveniently save scans to your Google drive. The scans are not always perfect but they are consistently better than other scanner apps that I've used. It has done everything that I have asked from it with very little hassle.
