While not an app that itself provides supplemental data, I can recommend the app StreetComplete (not affiliated - just a happy user) if you like OSM. It "game-ifies" the process of correcting and adding to OSM data by presenting little challenges and questions about nearby objects - e.g. "What is this building called?" or "Is there an ACME Corp. in this shopping center?" |
