Mastery App

Mastery is the simplest habit tracker that I'm currently developing for the iPhone using React Native.

You simply have to enter a habit you want to track daily. Once you complete it, simply mark it done (green) otherwise it remains grey. There's no option to skip a day, or set a weekly goal.

Mastery is ideal for tracking habits that you have to do everyday, like waking up early, or watering the plants. No cheat day. Your aim is to have a perfect week with all the habits marked green!
