Focus matters. But so does rest. PTimer is a Pomodoro timer that supports both — your way. 【Sound the shift】 Mark every work-to-break and break-to-work moment with a sound you actually like. Choose from 20 system sounds or bring in your own music or audio files. Set a different sound for each transition. 【Make the time yours】 Change the timer font to any typeface you like, including your own font files. 【Honor your rest】 Breaks you spend quietly — without touching or lifting your device — can be saved to Apple Health as mindful minutes (opt-in in Settings). 【More features】 · 5 color themes: Green, Silver, Blush, Indigo, Citrus · Widget support (Home Screen / Lock Screen) · Live Activity support · Control support — launch from Control Center, Lock Screen, or the Action button (iOS 18+) · Apple Watch support · Low power mode 【About Pomodoro】 25 minutes of focused work, followed by a short break — repeated. Session length and break duration are fully adjustable.
