Questions
Can Apple Watch do interval training?
Yes. In the Workout app, custom workouts add a warm-up, work and recovery intervals and a cool down, by time, distance or open, for most workout types. Cero’s Apple Watch app runs interval timers too, with rest by heart rate.
Do I need an Apple Watch for interval training?
No. Cero runs on iPhone and iPad on its own, with sound, voice and vibration cues. A Watch adds your heart rate.
Is Cero free on Apple Watch?
Yes. The Apple Watch app comes with Cero, which is free with every feature; Cero Pro adds unlimited saved timers and removes ads.
