# Cassini HD vs Geographic Encyclopedia

The clearest difference is review sentiment: Cassini HD at 94% against Geographic Encyclopedia's 50%. Cassini HD also leads on rating (4.3 vs 1.0) and ratings volume (6 vs 1). Geographic Encyclopedia's advantage is update cadence (every 4 weeks vs every 2 months) and price ($0.99 vs $1.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

Cassini HD costs $1.99 and Geographic Encyclopedia $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Cassini HD holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: Cassini HD has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 94% of Cassini HD's written reviews are positive against 50% of Geographic Encyclopedia's.

Cassini HD ships an update every 2 months, Geographic Encyclopedia every 4 weeks. The most recent releases landed on October 21, 2026 and October 31, 2026 respectively.
