# Worm World vs Supernova

The clearest difference is rating: Worm World at 5.0 against Supernova's 4.5. Worm World also leads on in-app purchases (none vs 10) and iOS requirement (6.0 vs 17.0). Supernova's advantage is update cadence (every 2 days vs every 31 months) and ratings volume (80 vs 1). On price and ads there is nothing between them.

Both are free to download. Supernova sells 10 one-off in-app purchases. Worm World asks for nothing beyond the download.

Worm World holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Supernova has 80 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 56% of Worm World's written reviews are positive against 76% of Supernova's, so the app with the better star average is not the one people write more warmly about.

Worm World ships an update every 31 months, Supernova every 2 days. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
