# Gemma GPS vs UTM Geo Map

The clearest difference is in-app purchases: UTM Geo Map at none against Gemma GPS's 2. UTM Geo Map also leads on ratings volume (93 vs 1) and review sentiment (100% vs 86%). Gemma GPS's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Gemma GPS sells 2 in-app purchases, starting at $199.99 per year. UTM Geo Map asks for nothing beyond the download.

Gemma GPS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: UTM Geo Map has 93 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 86% of Gemma GPS's written reviews are positive against 100% of UTM Geo Map's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on August 6, 2026 and September 21, 2026 respectively.
