Repeat your workouts and focus sessions in timed sets. DDANG is a routine interval timer that keeps workouts, stretching, and focus sessions moving with short sounds and haptic cues. Set your work time, rest time, and number of sets for routines such as planks, wall sits, dead hangs, stretching, or alternating periods of focus and rest. For repeated movements, set a target count and tempo (BPM). DDANG plays cues at consistent intervals to help you keep your rhythm without losing count. You do not need to keep looking at the screen. Short sounds and haptics tell you when to start, switch phases, prepare for the end, begin the final set, and complete the routine. ■ Made for people who want to · Repeat workouts in timed sets · Train with planks, wall sits, dead hangs, and other holds · Keep count during stretching and repeated movements · Alternate between focus and rest · Continue without constantly checking the screen · Review daily activity and streaks · Record workout heart rate with a compatible watch ■ Main features · Custom labels Save routines with names such as “Plank,” “Stretching,” or “Focus.” · Time-based intervals Set work time, rest time, and the number of sets. · Start countdown Choose your preparation time before a routine begins. · Sound and haptic cues Receive brief cues for starts, transitions, final sets, and completion. · Remaining-time cues Choose when to be notified before a work or rest phase ends. · Repetition counter Set a target count and tempo (BPM) for repeated movements. · Recommended templates Quickly start routines such as planks, wall sits, and dead hangs. · Tags Organize routines by workout, study, stretching, or your own categories. · Statistics and calendar Review active time, completed sets, active days, and streaks. · Backup and restore Export your data and restore routines and records on another device. ■ Use DDANG with your watch Install DDANG on a compatible watch to sync timers created on your phone and start workouts from your wrist. · Sync timers created on your phone · Start workout timers from your watch · Configure haptics, sounds, and in-app touch lock · Record heart rate during phone-started workouts · Sync watch-completed workouts back to your phone · Review average, minimum, and maximum heart rate · See heart rate trends for each workout set Heart rate recording requires a supported watch and the appropriate permissions.
