Routine Interval Timer - DDANG

Repeat your workout and focus routines in sets.
DDANG is a routine interval timer that guides repeated workout, stretching, and focus sessions with sound and vibration.
Set your work time, rest time, and number of sets freely for hold exercises like planks, wall sits, and dead hangs, short stretching routines, or repeated focus and break sessions.
For repeated movements, you can also follow a steady beat.
Set a target count or BPM, and DDANG will play sounds at regular intervals so you can keep your rhythm without losing count.
You do not need to keep watching the screen.
DDANG uses short sound effects and vibration cues for start, transition, remaining time, last set, and completion signals.

Short sounds and vibration tell you what to do next.
