I’ve seen that several commercial apps are using OpenStreetMap tiles/data which I really like.
I’ve downloaded the Gaia App after a recommendation of a friend, and was quite surprised to find no overlay in the corner which shows, that the tiles/data are from the OpenStreetMap project.
When you click on layers, than there’s a “© OpenStreetMap” but no link to a license, no name for a license, no link to the project etc.
I’m also quite unsure what they mean with “© Gaia GPS”. If they combine their database with OpenStreetMap they need to release their database under the same License (ODbL v1). I couldn’t find a download for or a way to otherwise access their combined database which they use.
Maybe someone can help me understand how this is not a violation of the ODbL.
