# Project Entropy vs Mecha Fire

The clearest difference is ads: Project Entropy at none against Mecha Fire's shown. Mecha Fire's advantage is review sentiment (41% vs 25%) and ratings volume (17K vs 1.4K). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Project Entropy sells 13 in-app purchases, starting at $9.99 per month and Mecha Fire sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Mecha Fire holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Mecha Fire has 17K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews point the same way: 25% of Project Entropy's written reviews are positive against 41% of Mecha Fire's.

Project Entropy ships an update every 2 weeks, Mecha Fire fortnightly. The most recent releases landed on October 16, 2026 and October 17, 2026 respectively.
