The app is open source, and it's author is very friendly to users. I even contributes myself a few lines of code.
I myself is badly organized and highly irrational. So I have a few note apps for recording ideas :) But the app I'm using when in a good productive mood when I going to solve a few tasks.
It gives some motivation and I really like design.
The app allows to store tasks on a WebDAV share so I storing them on a router with a USB disk.
Highly recommend it.
