# Crystal Caverns! vs Bubble Pop Star

The clearest difference is rating: Bubble Pop Star at 4.8 against Crystal Caverns!'s 4.2. Bubble Pop Star also leads on update cadence (every 6 weeks vs every 36 months) and ratings volume (16K vs 33). Crystal Caverns!'s advantage is in-app purchases (none vs 17) and review sentiment (86% vs 67%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Bubble Pop Star sells 17 one-off in-app purchases. Crystal Caverns! asks for nothing beyond the download.

Bubble Pop Star holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Bubble Pop Star has 16K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 86% of Crystal Caverns!'s written reviews are positive against 67% of Bubble Pop Star's, so the app with the better star average is not the one people write more warmly about.

Crystal Caverns! ships an update every 36 months, Bubble Pop Star every 6 weeks. Both last shipped on September 23, 2026.
