Interval Timer Set

Interval Timer Set is a focused local utility for setting private work/rest rounds with a simple on-device countdown. Open the app, use the visible controls, and use Share to export a plain text summary. Settings includes an in-app language picker for English, Japanese, Chinese, Spanish, French, German, and Portuguese. The app works on device. It does not require an account and does not include analytics, tracking, advertising SDKs, subscriptions, cloud sync, social features, or server upload. Safety boundary: local interval timer only; no medical, coaching, biometric, account, workout marketplace, or health-result claim.
