RepCount is a workout tracker for strength training. It's free, with no ads and no limit on workouts, routines or exercises. Premium adds charts, personal records, supersets, drop sets and export. Every workout starts with the weights and reps from last time, so you always know what to beat. Use it for whatever you train: a 5x5 or upper/lower program, a bodybuilding split, calisthenics, or a home gym with a pair of dumbbells. IN THE GYM • Log more than weights and reps: bodyweight exercises (assisted or weighted), timed holds, farmer's walks, and cardio with time, distance and calories • Warm-up sets, and notes on any set, exercise or workout • A rest timer that can start when you check off a set, with the countdown on your lock screen and in the Dynamic Island • Start a workout or routine with Siri or Shortcuts • Share a finished workout as an image ROUTINES AND EXERCISES • Build your own routines, save any workout as a routine, or repeat a past workout • Add your own exercises. Built-in exercises show a demo and the muscles they work YOUR DATA • Sign in with Apple, Google or email, and your workouts are backed up and synced between iPhone and Android • Works offline, even in a basement gym • Saves workouts, active calories and body weight to Apple Health PREMIUM • Your estimated one-rep max from every set, charted over time, so you can see your strength go up without testing a true max • Charts of heaviest weight, volume, sets and reps per exercise, plus workout frequency, duration and body weight • Personal records for every rep range, all-time and for each year • Exercise history and charts right from the workout screen • Supersets and drop sets • Export your workouts to Excel (CSV) QUESTIONS Can I see my progress without Premium? Yes. Every workout you've logged stays free to look back through, month by month, and each set starts from last time's numbers. Premium adds the charts, personal records and exercise history inside a workout. Is it good for beginners? Yes. Start with one of the built-in routines and build your own when you're ready. RepCount has been downloaded more than 2 million times on iPhone and Android. It's been on the App Store since 2013, with several hundred updates so far, and it keeps getting better.
