Bell Boxing Timer vs BJJ Reaction Timer

Bell is a clean boxing timer built for real training. Run boxing rounds without interruptions. Bell works in background, stays reliable on the lock screen, and lets your music keep playing while the bell still cuts through. PRESET WORKOUTS OR YOUR OWN Bell includes ready-to-use boxing workouts so you can start immediately. Use them as benchmarks based on common training formats (Tabata, bag intervals, conditioning rounds) or build your own custom workouts. FULL ROUND CONTROL Create workouts with flexible rounds, custom intervals, and variable work/rest durations inside a single round. This lets you simulate real boxing patterns, for example: short explosive combos, longer pressure phases, then brief recovery windows within the same round. COACH-STYLE INTENSITY BURSTS Add random intensity bursts that force sudden acceleration, like a coach shouting “go!”. These bursts push explosive output and help build fight-pace endurance. TRACK YOUR TRAINING Bell keeps a history of your workouts so you can see your routine over time and stay consistent with your training. BUILT FOR REAL TRAINING • Boxing • Heavy bag work • Sparring drills • MMA and kickboxing • HIIT and conditioning WHY BELL STANDS OUT • Reliable in background • Music friendly • Clear round progress • Flexible round structure • Simple setup • No ads COMPETE WITH FRIENDS New: a weekly leaderboard of training minutes with your gym buddies — via Game Center, no sign-up needed. The board resets every Monday, so every week is a fresh fight for the top. ROUND ALERTS Rest over? Bell tells you right on the lock screen — "Round 2 — Let's go!" You never miss the start of a round, even with the phone in your pocket. No fluff. Just a timer for real rounds.

BJJ Reaction Timer is a clean, distraction-free round timer designed specifically for BJJ practitioners. Configure your round length, number of rounds, break time, and warm-up period — then hit start and let the app run your session. Audio cues signal the start and end of every round so you can stay focused on the mat, not the screen. An optional **Random Reaction** mode introduces unpredictable prompts during rounds, helping grapplers simulate live rolling conditions and sharpen reactive decision-making. Named presets let you save multiple timer configurations (e.g. *Sparring*, *Drilling*, *Competition Prep*) and switch between them instantly.
