Rest by heart rate, not by the clock. A 90-second rest timer doesn't know whether today is a good day or a bad day. Your heart does. ZoneVibe watches your heart rate between sets and rounds, and taps your wrist the moment you've recovered. That's your signal to go again. No staring at your watch. No guessing. Just train, rest, feel the buzz, repeat. How it works? Pick your workout type: Strength, Functional, or anything else - Set your rest minimum (for example, 100 bpm) - Start from your iPhone, or tap "Start last zone" on your Apple Watch. No phone needed - Rest after each set. When your heart rate drops to your minimum, the watch vibrates. Go. - On a strong day you recover faster and get more work done. On a tired day you rest a little longer. Rest time that adapts to you, automatically. Built for • Strength and functional training: rest until you're ready for the next heavy set • CrossFit, HYROX and hybrid training: go again when your engine is ready, not when a timer says so • Circuits, kettlebells and HIIT: recovery-based intervals instead of fixed ones • Boxing, MMA and combat rounds: know when you're ready for the next round • Team-sport conditioning: repeat efforts on real recovery Also a heart rate guardrail! The same wrist tap works both ways: • Above: buzz when you've recovered down to your minimum (rest intervals) • Below: buzz when you go over a ceiling (Zone 2, easy runs, staying under a personal limit) • Between: stay inside a range (steady-state cardio) Set zones in BPM or as a percentage of your max heart rate.
