UBT: Ultimate BJJ Timer

Official IBJJF round times by belt, your own custom workouts, and alerts loud enough for a busy mat. No sign-up, no clutter, open it and roll.

UBT is a round timer built for jiu-jitsu, readable from across the mat, and quiet about everything that isn't the clock.

OFFICIAL IBJJF TIMES Every belt's match time is ready to go: white 5 min, blue 6, purple 7, brown 8, black 10. Train at the exact pace you'll compete at.

TRAINING FORMATS Drill, warm-up, sparring, long roll, shark tank and single match, the sessions your academy already runs, one tap away.

YOUR OWN WORKOUTS Set rounds, round length and rest. The app shows how the total breaks down: how many minutes rolling, how many resting. Save it and it's waiting for you next time.

BUILT TO READ AT A GLANCE A dark screen with a huge countdown and a ring that changes color as the round moves: green while you roll, amber in the final stretch, red in the last seconds, blue on rest. You'll know where you are without walking over to the phone.

SOUNDS THAT CUT THROUGH Eight tones, including gong, air horn, whistle, bell and buzzer, plus recorded voice calls for each moment of the session. Pick a different one for round start, rest and the end of the workout. Alerts play over your music instead of stopping it, and work with the phone on silent.

MADE FOR TRAINING Screen stays awake while the round runs. Works in portrait and landscape. English, Portuguese and Spanish, following your phone's language.

Free, with a single ad when you open the app, never during a round.
