Feature request live usage

[Tecnelm]

Hello, first of all, thank you for building this application — I really like the concept, it reminds me of my old hiking app.
I love the idea of having all this data decentralized and self-hosted. I have a few questions/suggestions:

1. Is a native Android/iOS app planned?
2. Having a mobile app could allow users to download trails for offline use during hikes
3. Live tracking: start the app and record your track in real-time, and follow your trace based on a downloaded trail.
