As a fellow developer and friend I had the opportunity to test the app during the beta.
Especially on iOS it's really fun and refreshing to use. It may not have all the bells and whistles of complex Todo or GTD systems. But that's what makes it so uncluttered and refreshing. It has every feature most users would want from this kind of app if you really need it without overwhelming you.
The app is continuously worked on and improved, so it will only get even better with time!
