A timer keeps you honest. No more rushing through sets or resting too long between rounds. You set the work, the rest, and the pace, and LastTimer holds the line so you can focus on training, not on watching the time. Built for rounds, tuned for everything. LastTimer runs jiu jitsu, boxing, MMA, Muay Thai, and wrestling rounds with a clean bell that cuts through a noisy room, and it is just as at home with HIIT, Tabata, circuits, yoga, meditation, or a Pomodoro block. NEW IN 1.4.0 - ON YOUR WRIST, IN SYNC, ONE SCAN AWAY - Apple Watch app: a real timer on your wrist that runs on its own, with no iPhone nearby. Start a round, drop your wrist, and it keeps running and taps you at every change. - Your timers, everywhere: iCloud keeps saved timers and workout history in sync across iPhone, iPad, and Apple Watch. Build a timer on the phone and it is already on your wrist. - Scan to run: hand someone a workout with a scan. It opens the timer instantly, with nothing to install. - Every built-in preset is on the Watch too, ready without saving a thing. ONE TIMER, EVERY SCREEN - A full native iPad app with a coaching dashboard: the whole session at once, a big ring beside a board of every round, session stats, and what is up next. - Presentation Mode: a full-screen room display for a TV or projector over AirPlay or a USB-C to HDMI cable, so the whole class reads the timer from across the mat. - Lock Screen and Dynamic Island controls: pause, resume, and skip a round without unlocking. - Interactive Home Screen widget: start a saved timer with one tap; pause, resume, or skip the running one. - Voice announcements: spoken round call-outs, a 3-2-1 countdown, and "Workout complete." - Named, colored rounds: label each slot (Warm-up, Guard Passing, Sparring) and the ring tints to match, everywhere the round shows. - Round presets: boxing, MMA, Muay Thai, wrestling, per-belt IBJJF match times, Tabata, and EMOM, ready in one tap. - Session history and streaks: every finished workout logged with a daily streak. - Share a timer: send any timer (rounds, names, colors) as a link a training partner imports. - Siri and Shortcuts: "Hey Siri, start Boxing Rounds in LastTimer." BUILD YOUR PERFECT TIMER - Prep, exercise, and rest periods - Multiple exercises per cycle, up to 10 cycles - A bell that mixes over your music and plays even on silent - Accurate in the background when you switch apps WORKS FOR - Jiu Jitsu, boxing, MMA, Muay Thai, wrestling - HIIT and Tabata - Circuit and strength training - Yoga and stretching - Meditation - Pomodoro study sessions - Cooking (yes, really) PRIVACY No account.
