Read full descriptionHide full description
One More is a rhythm timer for interval workouts such as rowing and indoor cycling, where effort alternates between faster and slower phases. Set fast, slow, and rest phases, then customize the pace, group structure, and number of rounds to fit your training plan. During a session, on-screen, audio, and haptic cues show the current phase and help you follow your planned rhythm. One More supports Apple Watch, so you can view and receive training cues on your wrist and check your iPhone less often. Use it at home or at the gym to organize interval workouts around your own plan.
