habTrack is a simple habit tracker. Add the habits you want to keep up and pick when they happen: every day, specific days, or every other day. Some habits need more than one tick, like drinking 4 glasses of water, so you can set how many times a day and count each one. Reminders go off at the time you choose, even if the app is closed. The calendar fills in as you go. Each day gets a square, and the darker it is, the more of your habits you finished that day.
