A free, drift-proof workout timer for AMRAP, EMOM, For Time, Tabata and intervals. Thruster is the most advanced AI training app. It writes your training, checks your form, warms you up and tracks your progress towards the goals you set. An AI coach for every way you train Seventeen ways to train β€” MetCon, Gym, HIIT, Calisthenics, Running, Mobility, Weightlifting, Powerlifting, Strongman, Kettlebell, Hyrox, Rowing, Cycling, Swimming, Boxing, Yoga and Bodybuilding β€” each with its own page, its own kit and its own goals. Tell the coach how long you have and it writes today's session from your logbook: your maxes, your recent sessions and how hard they were, the movements you still scale, and the equipment you actually own. Every session says which of your goals it moves. Form check: AI video analysis of your technique Film a set from the side. Thruster's AI watches your reps and tells you what to fix, where in the rep it happens, why it matters and a drill to correct it. Up to a minute, no sound. AI warm-ups for the session ahead Whatever you're about to do β€” a session the coach wrote, a benchmark, or the workout on your gym's whiteboard β€” Thruster writes a warm-up for those exact movements and loads. A training plan on your calendar Pick your days, what you want to train and a goal. Thruster lays out weeks of training with deload weeks built in, and writes each day's session on the day, from how your training is actually going. It tracks your progress Set goals that match how you train: a heavier lift, a faster benchmark, a 5 km time, strict pull-ups, a longer hold, sessions a week. Progress is measured from where you started. Log a result and Thruster tells you when it's a PR β€” Rx against Rx, scaled against scaled β€” and keeps your Rx rate on every movement. Scan the whiteboard Photograph the workout on the board and Thruster reads it into a timer and a log entry. It shows you what it read before anything is saved. A timer you can trust For Time, AMRAP, EMOM, Tabata, intervals and rest, with voice and haptic cues, and a clock that keeps exact time with the screen off. Built for real training 160 movements with Rx standards and scaling, 17 benchmarks, hero workouts and the Open, a strength log with estimated 1RM, and a plate calculator. In English, Deutsch, EspaΓ±ol, FranΓ§ais, Italiano, PortuguΓͺs and Χ’Χ‘Χ¨Χ™Χͺ.
