Round Sport Timer

Offline boxing & interval training timer for iOS. No account, no ads — just press start.

FAQ

Does the app need an internet connection?

No. Round Sport Timer is 100% offline. All profiles and settings are stored on your device only.

Why do sounds play even in silent mode?

That's intentional — in a gym you must hear the round signals. You can turn sounds off in Settings inside the app.

How do I build a workout with different intervals?

Create a new timer, switch its Type to “Custom”, and add sets of segments — each with its own duration, name and color. Sets can repeat (e.g. [Work 20s + Rest 10s] × 8).

My data disappeared after deleting the app

Data is stored locally, so uninstalling the app removes it. Profile export/backup is planned for a future update.
