# ASGuide vs Sky Academy

The clearest difference is in-app purchases: ASGuide at none against Sky Academy's 1. Sky Academy's advantage is ratings volume (197 vs 9) and device support (3 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Sky Academy sells 1 one-off in-app purchase. ASGuide asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for ASGuide against 4.9 for Sky Academy. That said, the two scores are not equally well evidenced: Sky Academy has 197 ratings behind it against 9, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Both ship on a similar rhythm, roughly every 4 months. Both last shipped on October 24, 2026.
