What is habit stacking? Habit stacking is a proven productivity technique that pairs a new, desired behavior with an existing, automatic daily routine. By using an established habit as a natural trigger, you bypass the need for relying on willpower, making it significantly easier to build consistent routines. After I pour my morning coffee, I will write down my top priority for the day. The coffee is the trigger; the new habit stacks right on top. How the app works? 1. Add a habit and the date you started it. 2. Keep your streak — the app tracks how many days you've kept each habit. 3. Watch habits level up as streaks pass 1, 21, and 365 days.
