SET YOUR WORKOUT Choose 1–20 sets and a rest period from 15 seconds to 9 minutes. Your preferred settings are remembered for next time. TIME YOUR REST Tap Start Rest after a set to begin a clear, easy-to-read countdown. See how many sets remain and feel a haptic alert when your rest is over. FOLLOW YOUR HEART RATE With your permission, view live heart rate during your session. The finishing summary shows your maximum and current heart rate, set count, and selected rest duration. SIMPLE WATCH CONTROLS Use a single rest countdown or move through multiple sets. Need to finish a break early? Triple-tap the countdown to skip the remaining rest. Built for Apple Watch.
