Gyro Mate

The application calculates the Sun azimuth based on observer's location and time of observation. No additional publications required: nautical almanac, etc.Once the azimuth is calculated, entering gyro bearing, heading, magnetic heading, variation will produce the result summary with all data required to keep the Compass Observation Book in right way.

App is not bad. The variation needs to be updated. Variation is off by almost 2 degrees based on most recent World Magnetic Model (WMM) or the International Geomagnetic Reference Field (IGRF) models.

Saved me a lot of time. Didn't experience any issues. Keep up the good work and thank you for making our lives on sea a little easier :)

Doesn't use gps to get lat/long. Have to enter it manually. Junk.
