Onelify
One habit. 66 days. Done.
Free · Designed for iPad. Not verified for macOS.
Stop tracking 10 habits and finishing none. Onelify focuses you on a single habit for 66 days — the science-backed length of forming a new routine.
Onelify is the habit tracker for people who are tired of overcomplicated apps that track twenty things and help with none.
The premise is simple:
Pick one habit. Do it for 66 days. Watch it become who you are.
WHY ONE HABIT?
Decades of behavior research keep landing on the same conclusion: people who focus on a single behavior change succeed dramatically more often than people who try to change several at once. Onelify is built around this idea — by design, you can only track one habit at a time.
WHY 66 DAYS?
A widely cited study from University College London found that new behaviors take, on average, 66 days to become automatic. Not 21. Sixty-six. Onelify shows you exactly where you are on that journey.
