# OSM Maps vs CoMaps

The clearest difference is ratings volume: CoMaps at 131 against OSM Maps's 1. CoMaps also leads on chart position (#160 vs unranked) and iOS requirement (15.6 vs 17.6). OSM Maps's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 80%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

OSM Maps holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CoMaps has 131 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of OSM Maps's written reviews are positive against 80% of CoMaps's.

OSM Maps ships an update every 11 days, CoMaps fortnightly. The most recent releases landed on September 20, 2026 and September 22, 2026 respectively.
