Whether you're rolling at open mat, drilling positions, or running competition-pace rounds, this timer adapts to your session. Set your work intervals, rest breaks, round count, and prep countdown — all in seconds.

KEY FEATURES

• Custom rounds: 1 to 50 rounds, 10 seconds to 60 minutes per round
• Quick presets: 5×5 min, 6×3 min, 8×2 min, 10×1 min
• Tap counter: log submissions, sweeps, or any move during work intervals
• Session log: last 10 sessions auto-saved on your device
• Drift-free timing: stays accurate even if your screen sleeps
• LOUD alarm cues: boxing bell or MMA gong that cuts through silent/DND mode — heard clearly even in noisy gyms
• Vibration feedback: strong haptic buzz on round end, rest end, and tap counter
• Wake Lock: screen stays on during active rounds
• Dark theme optimized for OLED displays
• Accessibility: full keyboard navigation, prefers-reduced-motion support, screen reader labels

USE CASES

— Open mat rolling: set 5×5 min with 1 min rest, tap each submission/sweep, review log after class
— Drilling: custom 10×1 min sets, no rest, no taps needed
— Competition prep: 6×5 min hard rounds with 1 min rest, simulate IBJJF/ADCC format
— Conditioning circuits: tabata-style 8×2 min with 30 second rest
— No-gi training: same flexibility, no gi/nogi distinction in the timer itself

WHAT MAKES IT DIFFERENT

Most timer apps are boxing-first or generic interval tools. BJJ Round Timer is built around how grapplers actually train. The tap counter alone makes it easier to track submission attempts across an entire session without breaking flow. The LOUD alarm that bypasses silent mode means you'll never miss a round transition, even mid-match or in a packed gym.

Five distinct screens guide your session: a setup screen with presets and custom controls, a prep countdown, the active round screen with circular progress and round pip indicators, a rest screen showing the next round number, and a done screen with full session stats.

The app runs on your device. No account, no sign-up. Your settings, preferences, and session history are stored locally and stay on your phone. It only uses the network to load a rewarded video when you choose to unlock a theme.

FREE TO TRAIN

The full timer is free, and it stays that way. No banner ads, no pop-ups, and nothing ever interrupts a round. If you want more, three extra color themes (Ocean, Ember, Ghost) can be unlocked with a single short rewarded video, completely optional. Skip it and every timer feature works exactly the same.

PRIVACY

To support the optional theme unlocks, the app shows rewarded video ads through Google AdMob, which uses your device's Advertising ID. You can reset or delete that ID anytime in your Android settings, and in the EEA and UK you are asked for consent first. We keep no accounts and collect no other personal data. Everything else stays on your device.
