# GTViewer vs ArcGIS Earth

The clearest difference is update cadence: GTViewer at fortnightly against ArcGIS Earth's every 3 months. GTViewer also leads on rating (3.8 vs 3.5) and review sentiment (50% vs 35%). ArcGIS Earth's advantage is ratings volume (45 vs 4). 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.

GTViewer holds the better App Store score, 3.8 against 3.5. That said, the two scores are not equally well evidenced: ArcGIS Earth has 45 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 50% of GTViewer's written reviews are positive against 35% of ArcGIS Earth's.

GTViewer ships an update fortnightly, ArcGIS Earth every 3 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
