Seven Watch Features
Surf intelligence on
your wrist
01
Auto Session Detection
Your Apple Watch or Wear OS automatically detects when you enter the water. No tapping, no "start workout" — just paddle out and your session starts recording. Machine learning trained on 10,000+ real surf sessions.
02
Real-Time Wave Counter
Counts every wave you catch in real time using wrist-based motion sensing. See your wave count accumulate on your watch face as you surf. Post-session, the data syncs to your RSJ progression timeline.
03
Heart Rate & Exertion Zones
Continuous HR monitoring throughout your session. See your real-time heart rate on your watch, zone distribution in the app, and cumulative exertion scores that help your coach manage your training load across a trip.
04
Paddle Power Tracking
Measures stroke rate, stroke consistency, and estimated power output during paddling intervals. See when your paddle efficiency drops and build the endurance data your coach needs to structure your dry-land programme.
05
Session Timer & Rest Tracking
Get a live timer on your wrist showing total water time, waves caught per minute, and cumulative paddle duration. The watch auto-detects rest periods on the beach so your active session data stays accurate.
06
Post-Session Sync
Your session uploads automatically when you tap "End" on the watch. Opens directly in your RSJ Mobile App coaching feed. Tag location, board, conditions, and how you felt — your coach sees everything.
07
Coach Alerts on Your Wrist
Get a tap when your coach posts a new session note, video analysis, or training plan update. Stay connected to your coaching without checking your phone. Custom per-surfer notification preferences.

The auto detection is incredible. I forget I'm wearing the watch. After the session I open my phone and the data is just there — wave count, HR zones, paddle time. It's like having a sport scientist in the water with me.

I've been wearing a smartwatch for years and the default surf tracking is a joke. RSJ Watch actually understands surfing — rest detection, paddle power, coach alerts. It's in a completely different league.

What changed: my coach used to rely on my memory. Now he sees my actual session data — wave count, HR, paddle consistency — and adjusts my training programme accordingly. The accuracy is game-changing.
