An interval timer that gets out of the way. Build a workout in seconds — work, rest, rounds, sets — then start it and let clear beep cues call every change. The whole builder is free, and so is every workout you save. One person, one workout, two screens. Start, pause, skip and end together on iPhone and Apple Watch when both are open — or run them independently, for two people training at once. • Work / rest / rounds / sets, exactly as you want them • Beep cues and haptics on every change • Unlimited saved workouts, plus a Quick Start you shape yourself • Home Screen widgets • Progress history, kept on your device Recommended by TiNa Slim — youtube.com/@TiNa_Slim Pro — one payment, no subscription. Removes the ads and keeps the workout running while you're away from the app, with a live countdown on the Lock Screen and in the Dynamic Island. Adds voice countdown, exercise announcements, the full progress insights, and the Apple Watch app. No account. No cloud. Nothing you record leaves your phone.
