# Radiant vs Sky Force

The clearest difference is price: Sky Force at Free against Radiant's $2.99. Sky Force also leads on ratings volume (2.1K vs 99). Radiant's advantage is in-app purchases (none vs 4) and ads (none vs shown). On review sentiment, update cadence and device support there is nothing between them.

Sky Force is free to download; Radiant costs $2.99 up front. Sky Force sells 4 one-off in-app purchases. Radiant asks for nothing beyond the download.

Radiant holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Sky Force has 2.1K ratings behind it against 99, so its average is the more settled of the two. Written reviews complicate that: 83% of Radiant's written reviews are positive against 89% of Sky Force's, so the app with the better star average is not the one people write more warmly about.

Radiant ships an update every 3 months, Sky Force every 2 months. Both last shipped on October 15, 2026.
