# Gemma GPS vs UTM Geo Map Y2Tech

The clearest difference is rating: Gemma GPS at 5.0 against UTM Geo Map Y2Tech's 3.8. Gemma GPS also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). UTM Geo Map Y2Tech's advantage is update cadence (every 2 weeks vs every 2 months) and review sentiment (100% vs 86%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Gemma GPS sells 2 in-app purchases, starting at $199.99 per year and UTM Geo Map Y2Tech sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Gemma GPS holds the better App Store score, 5.0 against 3.8. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews complicate that: 86% of Gemma GPS's written reviews are positive against 100% of UTM Geo Map Y2Tech's, so the app with the better star average is not the one people write more warmly about.

Gemma GPS ships an update every 2 months, UTM Geo Map Y2Tech every 2 weeks. The most recent releases landed on August 6, 2026 and September 20, 2026 respectively.
