# Swarm Simulator vs IdleSpiral

The clearest difference is rating: Swarm Simulator at 4.7 against IdleSpiral's 4.2. Swarm Simulator also leads on review sentiment (78% vs 54%) and ratings volume (2.7K vs 79). IdleSpiral's advantage is update cadence (every 2 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Swarm Simulator sells 11 one-off in-app purchases and IdleSpiral sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Swarm Simulator holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Swarm Simulator has 2.7K ratings behind it against 79, so its average is the more settled of the two. Written reviews point the same way: 78% of Swarm Simulator's written reviews are positive against 54% of IdleSpiral's.

Swarm Simulator ships an update every 9 days, IdleSpiral every 2 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
