# Astro Kit vs Stars Blinker

The clearest difference is rating: Astro Kit at 4.6 against Stars Blinker's 4.0. Astro Kit also leads on in-app purchases (none vs 1) and ratings volume (51 vs 1). Stars Blinker's advantage is review sentiment (100% vs 87%) and iOS requirement (12.0 vs 17.6). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Stars Blinker sells 1 one-off in-app purchase. Astro Kit asks for nothing beyond the download.

Astro Kit holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Astro Kit has 51 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 87% of Astro Kit's written reviews are positive against 100% of Stars Blinker's, so the app with the better star average is not the one people write more warmly about.
