## What is Onelify?

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.

WHAT'S INSIDE
• A single large "Done" button — tap once per day, that's it
• A streak counter that builds your momentum
• A 66-day grid that visualizes your full journey
• Optional daily reminders at the time you choose
• Beautiful, minimal design with light, dark, and tinted icons
• 100% offline — your data never leaves your device
• No accounts, no tracking, no ads, ever

WHO IT'S FOR
• Anyone who has downloaded ten habit apps and given up on all of them
• People starting a new fitness, reading, meditation, or learning routine
• Minimalists who want one tool that does one thing well
• Students, creators, and professionals building daily practice

PRIVACY FIRST
Onelify collects zero data. There are no servers, no analytics, no third-party SDKs. Your habit and your progress live only on your device.

Start your 66 days today.
