No streaks to chase. Just show up, check in, and let the science do the rest. It takes 66 days to make a habit automatic.
Research from University College London shows that it takes an average of 66 days for a new behavior to become automatic. Not 21. Not 30. 66. That's why every streak in this app is designed around this scientifically proven timeframe.
