Verdict

The call

The clearest difference is ads: Morimens at none against Chaos Zero Nightmare's shown. Morimens also leads on review sentiment (79% vs 66%) and iOS requirement (12.0 vs 15.0). Chaos Zero Nightmare's advantage is ratings volume (15K vs 403) and rating (4.9 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Morimens sells 13 one-off in-app purchases and Chaos Zero Nightmare sells 45 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Chaos Zero Nightmare holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Chaos Zero Nightmare has 15K ratings behind it against 403, so its average is the more settled of the two. Written reviews complicate that: 79% of Morimens's written reviews are positive against 66% of Chaos Zero Nightmare's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Morimens ships an update every 6 weeks, Chaos Zero Nightmare every 3 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
