MatClock

MatClock – The Ultimate Round Timer for BJJ & Training
MatClock is a professional round timer built specifically for Brazilian Jiu-Jitsu, created by active coaches and competitors who needed something better than basic interval timer apps. It’s powerful enough for serious gyms — yet flexible enough for any sport or workout style.
Whether you're running:
BJJ or MMA classes
Boxing & Muay Thai rounds
HIIT, CrossFit, or circuit training
Personal training sessions
Home workouts
MatClock keeps your training organized, visible, and on-pace.
Designed for the Mat
Most timers were built for solo workouts — not live gym environments.
MatClock was engineered for real classes where clarity, volume, and speed matter.

External Display & Casting Support
