Software features include maps by © OpenStreetMap contributors, track storage limited only by your memory card size and the ability to share a spreadsheet report of the data you have gathered.
Our app uses location permission to make track of your route. Access to internet is used to load maps. External storage is used to save tracks on your memory card. In-app purchase billing is used if you choose to subscribe to our enterprise features.
