Why BIT?

About BIT

BIT was built for one simple reason: gym timers are either loaded with subscriptions and ads, or too basic for a real boxing or HIIT session. BIT runs the round, rest, and warning intervals you actually need for boxing, MMA, Muay Thai, kickboxing, and HIIT training, with custom profiles you can switch between in one tap. It's a native iOS app, built to start instantly and stay accurate through an entire session, whether you're training solo, running pad work, or coaching a class. No account, no ads, no data collection - just a timer that gets out of your way.
