About the app
The fewer rules, the more you keep.
Most habit systems fail because they ask too much. Lists of goals, stacks of commitments, daily reviews of everything you’re supposed to be doing. It’s exhausting — and eventually you stop.
My One Rule asks for exactly one thing. Write it in your own words. Check in every day. See what changes when you stop adding more and start committing to less.
