★ Turn your Phone into a cool gadget ★

Wind Speed is an anemometer (wind meter) that works surprisingly accurate since it only measures inputs to iPhone's and Headphones microphone. Various algorithms isolate wind from other sounds like noise and human voice.

✓ supports iPhone and iPod Touch
✓ sophisticated algorithm for converting wind noise to speed
✓ support for external microphone (iPhone Headphones)
✓ support for iPod Touch with Apple Headphones + Mic
✓ multiple units: Miles per hour (mph), Knots (Kn) feet per second (fps), kilometers per hour (km/h) and meters per second (m/s). Beaufort scale (B)
✓ hand driven rotor blades

Wind Speed can not measure winds below 5mph because low wind does not make noise in microphone. If you measure wind while driving a car, try at 45 angle towards wind for better results!

What's New in Version 3.0

- updated calibration
- now supports iPhone 4 and 4S

Not good w iPhone mic only

Says it will work with iPhone mic but I even tried changing the clean mic/ dirty mic settings & got a very wrong reading. Pro inflatable movie company I work with has a good wind reader - this one was off by 12mph!


I was standing on a dock in 35+ knots of wind caused by Tropical Storm Isaac. This thing never showed above 10.9 mph, regardless of the sensitivity setting used or the direction/angle that I held my phone. Don't waste your money.


This is without question the worst app ever. It in no way shape or form works, no matter what you do. Stay away from it if possible.
