How It Works
Choose What to Track
Set up habits that matter to you — daily exercise, water intake, journaling, meditation. Actions, metrics, or open reflections.
Reply to Our Text
Each day at your chosen time, you get a text. Reply naturally — "yes", "5 miles", "feeling great" — our AI handles the rest.
Watch Your Progress
See streaks, trends, and insights on your dashboard. Don't break the chain — the most powerful motivator there is.
“After a few days you'll have a chain. Just keep at it and the chain will grow longer every day. Your only job is to not break the chain.
Everything you need, nothing you don't
