# Star Guide vs AstroFinder

The clearest difference is rating: AstroFinder at 5.0 against Star Guide's 4.6. Star Guide's advantage is ratings volume (4.4K vs 1) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Star Guide sells 4 in-app purchases, starting at $1.99 per 7 days 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 4.6. That said, the two scores are not equally well evidenced: Star Guide has 4.4K ratings behind it against 1, so its average is the more settled of the two.

Star Guide ships an update every 2 weeks, AstroFinder every 9 days. The most recent releases landed on November 7, 2026 and October 28, 2026 respectively.
