Repeat workout and focus time in sets.

DDANG is a routine interval timer that connects repeating blocks of time
through sound and vibration for workouts, stretching, and focus routines.

Use it for hold exercises like planks, wall sits, and dead hangs,
short stretching routines,
or repeated focus/rest cycles.
Set duration / rest / sets freely for your routine.

You do not have to keep looking at the screen.
DDANG uses short sound effects and haptic feedback
to signal the start, transitions, the final set, and completion.

■ No need to keep watching the screen

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

· Start countdown - tick sound + light vibration every second
· Progress → rest transition - short transition sound + vibration
· Before rest ends - signal to prepare for the next set
· Final set start - distinct final-set cue

All cues are short.
Because DDANG uses sound effects instead of voice guidance,
it is less distracting while listening to music and helps keep your flow
during workouts or focus sessions.

■ The calendar keeps your routine going

Completed routines stack up on a calendar heatmap.
Even one set in a day keeps your streak going,
turning small repetitions into a visible record.

Records are handled on your device.
Routine records are not sent to a server.
When you need a backup, export and import a ZIP file yourself.
