About Grit
There are plenty of todo list and habit tracker apps for android. Some have the features I love while some have good UI design. While learning android I made this app for myself that brings together all the features that I like keeping everything simple. I eventually want to turn this app into a productivity hub with many social features like progress sharing in the form of beautiful cards.
