Consistentree: The Micro-Habit Forest
Consistentree is a free habit tracker that grows a tree as you build a habit over 66 days, the research-backed average time it takes a new behavior to become automatic. No account, no ads. Your habit data stays on your device.
How it works
Set a target goal and a stupidly small activation step, the tiny action that actually waters your tree each day (open the book, not read 20 pages). Miss a day and earn a Streak Shield to protect your progress instead of starting over. Grow your tree from sprout to sapling to a mature oak, sakura, or bonsai over 66 days, then keep watering into Prestige mode.
Why 66 days
Popular advice claims habits form in 21 days. Research from University College London found the real average is 66 days. Consistentree is built around that number instead of the myth.
