Very easy to use but I don't understand I have to keep it direct face towards wind or 45 degree in that case wind is stronger

Best anemometer I have tried. Pro version well worth buying. Only issue I have is app does not recognize temperature sensor on Samsung Galaxy Note 4.

I tried my level best to check its accuracy and satisfied with its accuracy.

Tested it and compared to another Anemometer and this app got pretty close. LG Nexus 4 handset. Considering a good wind meter will usually cost $200+ , and still not be very accurate, i am pretty happy with this app. I am finding the calibration instructions a little tricky though. Scared i wont remember the default settings and mess it up....?
