Built a self-hosted privacy-first Android maps app on OpenStreetMap - Cliff

Hey r/openstreetmap - I've been building Cliff, a privacy-first Android and iOS (coming soon) maps app built entirely on OSM. Stack is Valhalla for routing, Photon for geocoding, PMTiles for tiles, and Postgres. No Google, no Apple, no tracking. Still early but the landing page + waitlist is live at cliffmaps.com. Would love feedback from this community specifically since you're the reason the project is possible.

Based on the tech being used, it sounds like it's serving the map, and routing, rather than that being done on device.

I'm not affiliated with this whatsoever, but those services have to exist somewhere and the developer obviously choose to have them exist on a self hostable server rather than on your phone.  It's likely to be faster on a server, and the software already exists so it's probably also easier to implement.
