Measure your wind speed

Measure wind speed using only your iPhone or Apple Watch sensors—no internet required. Perfect for off-grid use or when you need real-time wind data.

WindWatcher is a stand-alone wind-measurement app that estimates wind speed using only your device's sensors. It does not require internet access or location data, and it remains unaffected by nearby obstacles like trees or buildings. It updates average wind speed and gusts in the background, includes a Watch app with complications, and supports iPhone widgets (including lock screen widgets). The app is 100% ad-free. There’s literally nothing else like it, and we hope you give it a try!
