# Supercluster vs SkySafari 7 Pro

The clearest difference is price: Supercluster at Free against SkySafari 7 Pro's $17.99. Supercluster also leads on in-app purchases (none vs 5) and review sentiment (69% vs 46%). SkySafari 7 Pro's advantage is rating (4.6 vs 4.4) and ratings volume (5.5K vs 191). On update cadence, ads and device support there is nothing between them.

Supercluster is free to download; SkySafari 7 Pro costs $17.99 up front. SkySafari 7 Pro sells 5 in-app purchases, starting at $4.99 per month. Supercluster asks for nothing beyond the download.

SkySafari 7 Pro holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: SkySafari 7 Pro has 5.5K ratings behind it against 191, so its average is the more settled of the two. Written reviews complicate that: 69% of Supercluster's written reviews are positive against 46% of SkySafari 7 Pro's, so the app with the better star average is not the one people write more warmly about.

Supercluster ships an update every 4 weeks, SkySafari 7 Pro every 5 weeks. Both last shipped on November 7, 2026.
