Crashes at the worst times

I love the format and the privacy lock to open the app, but it's very impractical because of crashing!

If I write for any period of time without 'saving' (I.e. Closing the app and reopening) then the app will crash and I will lose entire chunks of my new work. Very sad when this happens, and not time-efficient.

Please fix this major bug, and the app would be lovely!!

Uh... Why doesn't it save?

This App seemed like a good idea but I immediately noticed that it doesn't save. I suppose that's one way to keep your entities private but I'm sure that's not what most are looking for in such an app


Waiting for an update. Irritated I can’t use it.

Edit, have update but lost ALL entries...
