GymTimer: Interval Timer

Build every workout around the way you train.

GymTimer is a flexible interval workout timer for HIIT, circuits, strength training, conditioning and custom gym sessions. Set your timing once, press start and let GymTimer guide you through every exercise, rest period and round.

DESIGN EVERY INTERVAL
Choose your work and rest durations, number of exercises and total rounds. GymTimer also gives you a separate round reset timer, so you can take a longer recovery between rounds without compromising the pace of each exercise.

SAVE NEARLY UNLIMITED WORKOUT PRESETS
Turn any setup into a reusable workout preset. Load it instantly, rename it or adjust it whenever your routine changes. GymTimer recognizes matching configurations to keep your preset collection organized and free from duplicates.

FOLLOW A TIMER BUILT FOR TRAINING
Stay focused with a smooth visual progress timer, clear exercise and round counters, pause and navigation controls, sound options and haptic feedback. Customize the timer face, gradients and app theme to match your style.

TRACK WORKOUTS THAT ACTUALLY COUNT
GymTimer records completed exercises, rounds, workout time and finished sessions accurately. Review your workout history, repeat previous sessions and monitor your progress through weekly and monthly calendars.

BUILD CONSISTENCY
Set a daily activity goal, grow your workout streak and unlock new streak badges as you keep showing up. Streak protection helps preserve your momentum when you miss a workout window.

EARN AWARDS AND CLIMB THE RANKING
Complete workouts to earn trophies and progress through multi-level awards for workouts, training time, exercises, rounds, active days and more. Compare monthly trophy totals in the ranking and start fresh when each new calendar month begins.
