Questions

Are the grids accurate?

Grids are calculated with standard WGS 84 / UTM formulas and match NATO topographic maps. Your own position depends on your phone’s GPS, usually within a few metres outdoors.

Can it export to ATAK or Google Earth?

Yes: save your map as KML (Pro) for ATAK, Google Earth and GIS. ATAK data packages with military icons are on the roadmap.

Is it free?

The live grid, grid lines and pins are free. Pro adds mils, the compass and Go to; Premium adds unit symbols, team maps, overlays and light data.
