Built for you,
not for profit

We were tired of interval timer apps that lock basic features behind subscriptions. So we built one that gives you everything — for free.

Absolutely Free

No in-app purchases. No premium tiers. No "free trial" that expires. Every feature is unlocked from day one and stays that way forever.

No credit card needed
No hidden costs, ever

Focus on the workout, not the app
