The app is perfect if you just want to remind your self to call someone, or take out the trash when you get home. Instead of telling you at a specific time, it lets you know every time you look at your phone and you can do it when you feel that you have the time.
The app is still in development and there are some features that may not work as they should. But the core funktions of the app work.
For now you have to have android 4.1 or higher for the app to work. If there is demand for lower versions, I will try to add them as well.
