# Geodata Map Viewer vs CoMaps

The clearest difference is rating: CoMaps at 4.7 against Geodata Map Viewer's 4.3. CoMaps also leads on ratings volume (142 vs 32) and iOS requirement (15.6 vs 26.0). Geodata Map Viewer's advantage is update cadence (weekly vs fortnightly) and review sentiment (89% vs 80%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

CoMaps holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 32 and 142 respectively. Written reviews complicate that: 89% of Geodata Map Viewer's written reviews are positive against 80% of CoMaps's, so the app with the better star average is not the one people write more warmly about.
