Variometer, Vario, G_Variometer, TrackerParagliding, hang gliding and all air sports and skiing, sailing, mountain climbing, etc.Tracker instruments for all Outdoor sports.Flight instruments is expensive, but your phone is also expensive equipment.Your phone is better than that , you can perform a variety of functions.Using Compass & GPS & Pressure Sensor, flight time, speed, altitude, vertical speed is displayed.If your phone is equipped with pressure sensor, In air sports mode, variometer functions can be maximized.Pressure Sensor sensitivity of this filter using the Fourier Transform is better than any other filter using a simple lowpass filter or kalman.Therefore more precise user setting is possible.After simple one click, Ready to take off at once, auto-start-stop, manual-start-stop is possibleBig font and high contrast raised the visibility in outdoor.Through manual built in the app, you can learn easily how to use.Flight time, battery level, GPS status, and vertical speed, maximum speed, speed, maximum altitude, altitude, Hpa pressure, temperature (varies by altitude), weather (wind direction, wind speed), Task orientation, remaining distance, the total path length are displayedIt displays the direction and intensity of drift and thermal detecting also.Waypoint and Route creation is easier and faster than any other app.Map of the Google, OSM, mapquest, Naver is in use.Track play function is best function same as seeing the actual flight.Indexing and rewinding and the execution speed can be adjusted.Seeing track thumbnail, you can easily find a specific flight record andYour indexing speed can be also fast through altitude graph.Track files can be sent via email to other users andIn addition, KML, GPX files are saved and automatically converted.Navigation displays to the users the real-time shortest course from the current location and flight direction to next task, remaining distance, needed altitude against glide ratio In briefing, share discussion with colleagues easy.The units (mile, feet, meter, knot, ft / s, m / s, mph, kph, ?, ?) can be freely selected.Coordinate system of the DD-MM-SS.SS, UTM, WGS84, etc can be selectedWhen performing in background Mode, track can be recorded throughout the day precisely andDuring the mode, the sonic variometer functions and task passing, starting height sound alarm can be performed continuously.The altitude can be set in a variety of ways.Based Terrain Elevation, sea level air pressure reference, GPS altitude, the user manual setting is possible.GPS environment will be best in flight, You can get reliable performance.For feature requests and uncomfortable, please send mail [email protected]
