# Worm World vs Koitopia

The clearest difference is rating: Worm World at 5.0 against Koitopia's 2.1. Worm World also leads on in-app purchases (none vs 5) and review sentiment (56% vs 47%). Koitopia's advantage is update cadence (every 5 weeks vs every 31 months) and ratings volume (16 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Koitopia sells 5 one-off in-app purchases. Worm World asks for nothing beyond the download.

Worm World holds the better App Store score, 5.0 against 2.1.
