TimerSimple

The simplest interval timer for workouts. Set your work and rest, hit start, and focus on your training. Live Activity keeps your timer visible on the Lock Screen.

FEATURES

• Work and rest intervals: set custom durations and let TimerSimple guide you through each round. • Set and rep tracking: keep count without looking away from your form. • Overtime mode: if you push past the planned time, the timer keeps going so you can log the real effort. • Workout history: every session is saved locally so you can review past workouts and track consistency. • Categories: organize workouts by type (strength, cardio, mobility, or your own). • Live Activity: timer stays visible on the Lock Screen and in the Dynamic Island. Glance down mid-set without unlocking your phone. • Audio cues: subtle sounds signal phase transitions, with a volume slider if you want them quieter during music. • Dark mode: easy on the eyes in the gym or at home.

DESIGNED FOR FOCUS

TimerSimple runs entirely on-device. There's no sign-up, no cloud sync, no tracking, and no network requests. Your workout data never leaves your phone.

Built with iOS 26's native design so it feels at home on your device.

PERFECT FOR

• HIIT and interval training • Circuit workouts • Stretching and mobility routines • Rest timers between strength sets • Any activity that needs a clean, reliable countdown
