# Topo GPS vs UTM Maps

The clearest difference is rating: UTM Maps at 5.0 against Topo GPS's 4.5. UTM Maps also leads on review sentiment (100% vs 70%) and update cadence (every 10 days vs every 3 weeks). Topo GPS's advantage is ads (none vs shown) and ratings volume (463 vs 4). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Topo GPS sells 18 in-app purchases, starting at $18.49 per year and UTM Maps sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

UTM Maps holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Topo GPS has 463 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 70% of Topo GPS's written reviews are positive against 100% of UTM Maps's.

Topo GPS ships an update every 3 weeks, UTM Maps every 10 days. The most recent releases landed on September 25, 2026 and August 15, 2026 respectively.
