Your workout, live and connected
Per-set heart rate streamed from your wrist, mapped to every exercise — the core of how Iron Karnet trains with you.
Start on your wrist. Watch it live on your phone.

- Closes your Apple Fitness Activity Rings — no Watch needed
- No heart rate device needed — workouts track everything else
