In short: iKitesurf and WindUp both do kite-specific live wind, but WindUp keeps the alarm free instead of behind Premium. iKitesurf has run as the kite arm of the WeatherFlow / Tempest network for years; WindUp is the newcomer with a sharper alarm UX and a free tier that doesn't lock the alert away.

This isn't a hit piece. iKitesurf is a serious app — here's where they shine.
And where WindUp picks up the slack.
iKitesurf's US station data is excellent, and longtime members who ride flagship spots get real value from the community layer. But paying a membership mostly to see live wind — then still missing sessions because alerts don't break through silent mode — is the exact gap we built for. Try the free thing first; upgrade to membership only if you miss what it doesn't have.

You don't have to choose. Most riders use both — keep iKitesurf for the forecast and add a free live wind alarm that wakes you the moment your spot fires.
