As a part of an application suite this application manages asset locations supported by the DIYGPSTracker companion app. Check out the application website for more information. The application's philosophy is Do-It-Youself: it may need some technical expertise, but all the recorded data is governed and managed by you. The app doesn't record data in other databases than your own Firestore.
