66 Days - Habit Tracker

Creating good habits.

Free · In‑App Purchases · Designed for iPad

UCL. I studied habits at University College London. The average time it takes to build habits is 66 days. You do not have to put much effort into habits. Because if you repeat the behavior long enough, it will become a habit and automatically happen. If you check more than one habitual activity per day, continuous days will continue. Go ahead for 66 days and make your habits a goal for action right now. [Special Features] Set goals on a project-by-project basis and form habits.
