WindUp
Read full descriptionHide full description
Wind doesn't wait. Neither should you. WindUp watches your spot around the clock and rings your phone the moment the wind is right — through Silent, through Do Not Disturb, through Focus. Set it tonight, sleep properly, and wake up only when it's actually worth getting up for. SET YOUR CONDITIONS, NOT AN ALARM CLOCK • Minimum wind speed — and a maximum, if you have a ceiling • Wind direction sectors — only the ones that work at your spot • Days and a time window — no 4am ring on a work night • Snooze, ringtone and volume, all yours AN ALARM THAT ACTUALLY RINGS Most weather apps send a notification you will never hear. WindUp rings like a real alarm, even on Silent. And if you sleep straight through it, it can call your phone. LIVE WIND FROM REAL STATIONS Thousands of live weather stations across Europe and beyond. Real readings — average, gusts, direction and temperature — not a model's best guess. SEVEN DAYS AHEAD An AI wind forecast for every station, so you can plan the weekend on Tuesday. FIND YOUR NEXT SPOT Every station on one map. Zoom, tap, and see what's blowing right now. WIND COMPASS Hold your phone flat and see exactly where the wind is coming from, relative to where you're standing. TIDES Tide curves and high and low times for coastal spots, right next to the wind. WINDUP PRO • Unlimited wind alarms • Tides for every spot • Dark mode • Home-screen widgets Built for kitesurfers, windsurfers, wingfoilers, sailors, and anyone whose day depends on the wind.
