Wearables

Use Apple Watch for the moment. Use iPhone for the full picture.

Pair Apple Watch for quick actions and supported workout controls, then review the complete result in Zenith on iPhone.

Start, pause, resume, and end supported workouts from your watch.

If phone and Watch briefly separate, reopen Zenith on both devices and allow the workout to settle before starting another one.

Use iPhone for route, pace, elevation, workout details, and the final saved summary.
