No control. Outdated design. Ads everywhere. Sound like your current timer app? Resero is the one exercise timer you need, from a quick 10-minute home workout to fully custom training. Resero is modern, clean and built to grow with you. Squeeze in a short HIIT session in your living room, or take fine control over every rep, set and round the way athletes and coaches do. Your goals won't wait, so why should you? EVERYTHING YOU NEED IN ONE APP A Timer That Just Works: Big, clear and easy to read from across the room, in portrait or landscape on iPhone and iPad, for HIIT, Tabata, EMOM, circuits and much more. Your Own Routines: Build workouts from scratch and set every interval, rep, set and rest period exactly how you train. A Workout Library for Every Level: Ready-to-go workouts from beginner to pro. Pick one and start in seconds, or tweak it to fit you. NEW! Workout Analytics with Apple Watch: See your heart rate zones, training load and recovery after every session, so you know exactly how hard you worked. Your data stays on your device, private to you. Requires an Apple Watch paired with your iPhone. Apple Health and Apple Fitness: Your workouts are saved to Apple Health and count toward your Activity Rings when you train with iPhone and Apple Watch. Good to know: Analytics, Apple Health and the Apple Watch app need an iPhone with a paired Apple Watch. On iPad, you get the timer, library, custom workouts, sub-timers and progress calendar. Resero stands for REps, SEts and ROunds, the building blocks of every workout. WHY YOU'LL KEEP USING IT Apple Watch App: Start, pause and skip intervals from your wrist, with live heart rate and calories. Sub-Timers and Rep-Based Intervals: Count reps instead of seconds. Swap 60 seconds of push-ups for 12 push-ups at your own tempo: 1s down, 2s hold, 1s up. Resero guides you through every rep for perfect tempo control. Plays Nice with Your Music: Resero lowers your music during cues, then brings it right back. Runs in the Background: Change a song or answer a text without stopping your timer. 100% Ad-Free: No pop-ups, no banners, no interruptions mid-workout. Progress Calendar: Every session is logged automatically, so you can watch your progress grow week by week. Made for Sweaty Hands: Big buttons you can hit mid-workout without looking twice.
