# GlobeViewer vs Terra

The clearest difference is review sentiment: Terra at 100% against GlobeViewer's 33%. Terra also leads on rating (5.0 vs 3.4) and in-app purchases (none vs 11). GlobeViewer's advantage is update cadence (every 6 weeks vs every 3 months) and ratings volume (5 vs 1). On price and device support there is nothing between them.

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

Terra holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: GlobeViewer has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 33% of GlobeViewer's written reviews are positive against 100% of Terra's.

GlobeViewer ships an update every 6 weeks, Terra every 3 months. The most recent releases landed on October 8, 2026 and October 7, 2026 respectively.
