The wind forecast that actually knows your spot. Not a generic global model. Not a guess. Yours. Locally calibrated. For 451 spots worldwide. When KiteOracle says 22 knots, you get 22 knots. When it says Big Air is on, Big Air is on. Less driving for nothing. More days on the water. Bigger boosts. That's the whole point. What's inside: • 16-day spot-local forecast, hour by hour • Big Air potential — chance of a 5m, 10m or 20m boost, per hour • Spot intel that reads like a local told you • Historical data, month by month, spot by spot • Wind alerts on your favorite spots — get pinged when conditions hit • Big Air travel search, filtered by weather and nightlife • Webcams, photos, map view For kiters who want to know — not guess.

WHAT MAKES RSL UNIQUE RigSize Live is the only app that combines your own tracking, wind data, spot data and rig data. Every session is automatically linked to the wind at that moment, the spot and the sail, board and fin you used. So you see which gear works in which wind at which spot, based on real sessions. FULL SESSION TRACKER Start your session in the app or on your watch and you're live on the spot map. Your GPS track, top speed, average speed, Alpha 500, distance and heart rate come in automatically, linked to your rig, the wind and the spot.

Pick your sail, board and fin on your wrist, start your session and share your rig live on the spot map without opening your phone. Follow your speed, distance and heart rate live on your watch. Afterwards the session lands in RigSize Live with your rig, the spot and that day's wind. On Apple Watch Ultra you start with the Action Button. Garmin users get RSL Tracker free in the Connect IQ Store. SYNC FROM GARMIN, SUUNTO AND APPLE HEALTH Sessions from your Garmin sync automatically via Garmin Connect, from your Suunto via the Suunto app, and from any watch that writes to Apple Health. You can also upload a FIT or TCX file. RELIABLE WIND FORECAST Hourly updated forecast per spot, plus live readings from nearby weather stations that refresh every 10 minutes.

Never miss a good day again. PERSONAL INSIGHTS Which board and sail combo makes you fastest? What is your Alpha 500 per combo? Which gear do you never actually use anymore?
