# Copernicus Sentinel vs GlobeViewer

The clearest difference is rating: Copernicus Sentinel at 4.3 against GlobeViewer's 3.4. Copernicus Sentinel also leads on in-app purchases (none vs 11) and ads (none vs shown). GlobeViewer's advantage is review sentiment (33% vs 14%) and iOS requirement (12.0 vs 14.0). On price, update cadence and device support there is nothing between them.

Both are free to download. GlobeViewer sells 11 one-off in-app purchases. Copernicus Sentinel asks for nothing beyond the download.

Copernicus Sentinel holds the better App Store score, 4.3 against 3.4. Both are backed by a comparable volume of ratings — 18 and 5 respectively. Written reviews complicate that: 14% of Copernicus Sentinel's written reviews are positive against 33% of GlobeViewer's, so the app with the better star average is not the one people write more warmly about.

Copernicus Sentinel ships an update every 2 months, GlobeViewer every 6 weeks. The most recent releases landed on July 27, 2026 and August 14, 2026 respectively.
