# Zombie Tsunami vs Gravloop

The clearest difference is in-app purchases: Gravloop at none against Zombie Tsunami's 10. Gravloop also leads on ads (none vs shown) and rating (5.0 vs 4.5). Zombie Tsunami's advantage is ratings volume (13K vs 1) and iOS requirement (12.0 vs 26.5). On price and device support there is nothing between them.

Both are free to download. Zombie Tsunami sells 10 one-off in-app purchases. Gravloop asks for nothing beyond the download.

Gravloop holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Zombie Tsunami has 13K ratings behind it against 1, so its average is the more settled of the two.
