Over the last few weeks I’ve been hard at work building a FOSS maps app for Android from the ground up based on Material 3 components and industry standard maps tooling. It has online and offline modes, and integrates well with self-hosted maps services like Headway[0] deployments. I’m really quite pleased with it and I hope others enjoy using it as much as I’ve enjoyed making it. I’m about 2 weeks in to development so expect some bugs. But it has most of the features you’d expect like search, directions and navigation. It’s shockingly usable already.

I’ve been yearning for something better in the FOSS maps space for a long time. I don’t think I’m the only one. I’m really hopeful that Cardinal Maps can grow into that something for myself and others.

If you’re stoked about this project I’d appreciate contributions and beta testers. There’s an obtainium link in the repo README.md if you want updates. :)
