Features for the 2018 app (GT2)

React Native/Redux app for both Android and iOS

Original was just Android
Full serious app

Original was just a proof of GPS (which still works), new will be a full featured implementation of the nominal concept.
Backend service available as in app purchase

Via a servant based API, with much additional stuff and as a showcase app in my infrastructure and praxis
OSS as before

But backend elements will be in my git repo; Complete front-end app sources will replace the old here but documentation, build support will be in my domains. The app itself will be free as before on Play and App Store but the watchOS app will be priced.
