Overall, this was my go to app, but recently I decided to find a replacement, which I did. Plus my replacement app is even much better.
Why did I dump "Documents"?
Reason 1. The annoying splash screen. I finally got tired of getting that splash screen shoved in my face. Even if it is once a day (or whatever bizarre scheme they use), it is annoying, wastes time, and is totally useless. When I emailed support, the person replying didnt even know what a splash screen is. Think of how disastrous life would be if every app you opened first shows a splash screen. Plus, even Apple suggests not to use splash screens.
Reason 2. They support NAS (Windows SMB), but it has flaws. I found their syncing works sometimes and hangs other times. When I emailed support, their response was generally "It is my iPads problem, not theirs". Well, if you supply a feature, then get it to work instead of passing the buck to the user.
So in summary, goodbye Readdle.
