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.
