Paraglider & Hang Glider Variometer By TÜRKAY BİLİYOR
This software is designed for devices with barometric sensor and gps sensor. But it will also run on devices with just a GPS sensor.
You may use your device as real variometer. Barometric sensor will give you more accuracy and make software a real variometer for your para-glider.
Variometer Pro allows you to record igc file directly to the sdcard automatically..
Also able to send live data to www.livetrack24.com,
for this you could have internet access and fill your livetrack24 account info on settings page.

Flight log file path is \\sdcard\variolog (app will warn you about path)

The red side of needle on compass is showing wind direction.
You can change vario, filter settings and pilot profile from settings button.
Default and optimum filter dumper level is 1. I used 2 Kalman filter for vario.
Alt+ and Alt- is altitude offset

You can copy utm coordinate to clipboard by pressing on the utm textbox.
