Vaavud’s Sleipnir can turn your smartphone or tablet into a portable meteorological tool

Sleipnir is a wind meter that connects to your device through the earphone jack. It’s ideal for kitesurfing, sailing, or any sports related to the use of wind power. You can easily capture wind measurements using its companion app.

Sleipnir has two curved blades that send data to its internal optic sensor to measure 2-40m/s wind speeds with an accuracy of 44,100 measurements per second. It can also capture the wind direction which no other smartphone gadget can do.

The app can also provide you with wind measurements from other users for the last 24 hours. You can use these to gauge the weather conditions before you embark on your water adventure. The app also automatically records all previous measurements for future reviews.
