Repeat workout and focus routines in sets.

DDANG is a routine interval timer that helps you continue repeated sessions, such as workouts, stretching, focus blocks, and rest breaks, through sound and vibration.

Use it for hold exercises like plank, wall sit, and dead hang,
short stretching routines,
or repeated focus and break sessions.

Set your active time, rest time, and number of sets freely.

You do not need to keep watching the screen.
DDANG guides start, transitions, final sets, and completion with short sound effects and haptic vibration.

■ No need to keep watching the screen

Short sound effects and vibration tell you what to do next.

All cues are short.
Because DDANG uses sound effects instead of voice guidance, it stays lightweight while listening to music, working out, stretching, or focusing.

■ Stats help you keep the routine going

Completed routines are saved into stats and calendar records.

You can check active time, completed sets, active days, and streaks in one place.
With tags, you can also view records by workout, study, stretching, or any routine category you create.

Your routine records stay on your device.
They are not sent to a server.
When you need a backup, you can export and import your data as a ZIP file.
