# Project Entropy vs Idle Star Empire

The clearest difference is review sentiment: Idle Star Empire at 75% against Project Entropy's 24%. Project Entropy's advantage is rating (4.4 vs 3.8) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Project Entropy sells 10 in-app purchases, starting at $9.99 per month and Idle Star Empire sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Project Entropy holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Project Entropy has 1.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 24% of Project Entropy's written reviews are positive against 75% of Idle Star Empire's, so the app with the better star average is not the one people write more warmly about.

Project Entropy ships an update fortnightly, Idle Star Empire every 2 weeks. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
