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.
Why MatClock Is Different
Mat-Readable Display
Large, high-contrast countdown timer visible from anywhere in the gym.
Loud, Distinct Audio Cues
Choose bells, buzzers, or horns that cut through crowd noise and signal rounds clearly.
Fully Custom Rounds & Rest
Create any round length or rest interval — perfect for beginners’ classes, advanced training, or competition prep.
One-Tap Presets
Launch common drills and class timers instantly without rebuilding sessions every day.
External Display & Casting Support
Mirror the timer to TVs or projectors so the whole room stays synced.
Built for BJJ — Works for Everything Else
Made for grappling rooms but perfect for MMA, boxing gyms, fitness studios, schools, and home training setups.
Perfect for:
Academy owners
Coaches and instructors
Competitors and hobbyists
Personal trainers
Anyone running interval-based training

For less than the cost of a cup of coffee, you get a professional gym timer designed to make every class run smoother.
Train smarter. Run better classes. Focus on the work — MatClock handles the time.
