Yess!

Please make an effort to improve underlying OpenStreetMap dataset:

https://streetcomplete.app - basic task-based, on-the-ground, app for Android

https://every-door.app - intermediate on-the-ground app for smartphones

https://rapideditor.org - AI-assisted mapping in browser

https://www.hotosm.org - task-based mapping in browser

https://josm.openstreetmap.de - advanced editor for desktop

Two things I would love to see in the FLOSS mapping ecosystem:

1. A POI/favorites app that maintains a local database with an API for other apps to access it. Apps could then store markers there instead of in their own private db, so that points added on one map app can be instantly available in other apps.

2. A shared traffic data service. Any OSM map app could contribute to the same data, helping reduce Google's advantage in live traffic data.

Obviously, both of these would need privacy protections and be subject to user choice. And there should also be some requirement that both reading and writing be supported, to ensure apps reading POI data don't lock in new data, and to prevent apps reading traffic data from freeloading.

Does this work better than OsmAnd in any way? The latter has been around for a long time and just works. Perhaps the best feature is that maps can be downloaded and used completely offline. It's the natural map app on a degoogled Android system like Graphene.

The main downside relative to commercial apps like Google Maps is that you often need to input a full address instead of entering a business name or something like "Burger King near me."

Neat, I was not aware of this mechanism. Is there any way to get map (tile) data from CoMaps into another app?
