Stop chasing willpower. Build momentum with Atomic Flux.
Atomic Flux is a dead-simple habit tracker that turns tiny daily wins into streaks you'll actually keep — fully private on your device, unless you choose to back up.
Small enough to actually do. Every single day.
Tiny habits, real streaks
Add a habit in seconds, mark it done with one tap, and watch your streak grow. No forms, no friction — just the tap that keeps the chain going.
Your streak, right on your Home Screen
The "Habit Streak" widget keeps your progress one glance away, so the habit stays top of mind without opening the app.
Level up as you build momentum
Every completed habit earns XP, coins, and gems, and levels you up over time — small, satisfying proof that it's adding up.
Private by default
Every feature works fully on-device with no account at all. Sign in only if you want backup and sync across devices — that's the only thing it's for.
Nothing leaves your device unless you choose to sign in.
We wrote our privacy policy in plain English on purpose.
No dense legal maze — just a clear account of what Atomic Flux collects (almost nothing, unless you sign in), what it's used for, and how to delete it whenever you want.
