# Stellarium Mobile vs AstroFinder

The clearest difference is ratings volume: Stellarium Mobile at 40K against AstroFinder's 1. Stellarium Mobile also leads on chart position (#57 vs unranked). AstroFinder's advantage is update cadence (every 9 days vs every 5 weeks). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Stellarium Mobile sells 2 in-app purchases, starting at $1.99 per month and AstroFinder sells 1 in-app purchase, starting at $12.99 per year. Whichever you choose, the download price is not the number that matters.

AstroFinder holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Stellarium Mobile has 40K ratings behind it against 1, so its average is the more settled of the two.

Stellarium Mobile ships an update every 5 weeks, AstroFinder every 9 days. The most recent releases landed on November 10, 2026 and October 28, 2026 respectively.
