KnotNow is officially on the App Store.

Completely free from day one
We are focused on building the best wind sports community on the water. Grab the app, sail, wing, or foil, upload or sync your session, and tell us what works. The more honest the feedback, the faster we can make this the app we always wished existed for UK watersports.
What you get in the app
The iPhone app brings together the two sides of KnotNow:
- Sessions & debrief: Speed, VMG, tack and gybe metrics, leg asymmetry, foil time, gear-filtered stats, achievements, and logbook history.
- Forecasts on the go: Your favourite spots, hourly wind, tide, and sewage discharges and water-quality to help decide whether to rig up or stay in the van.
How to get started
- Download KnotNow from the App Store.
- Sign in with the same account you use on knotnow.co.uk (or create one in the app).
- Log a session — record on the phone, sync from Strava, or upload a GPX from your watch.
- Open the app for session analysis: map, legs, turns, speed intervals, and the stats that actually explain the session.

Help us build something epic
We built KnotNow for people who care about watersports. If that is you — racer, weekend club sailor, foiler, or windsurfer chasing a PB — we would love you in the community.
Download the app. Get out on the water. Then tell us what broke, what confused you, or what you cannot live without.
