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.

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."
