# Swarm Simulator vs Critical

The clearest difference is review sentiment: Swarm Simulator at 78% against Critical's 18%. Swarm Simulator also leads on rating (4.7 vs 4.4) and ratings volume (2.7K vs 125). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Swarm Simulator sells 11 one-off in-app purchases and Critical sells 17 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 4.4. That said, the two scores are not equally well evidenced: Swarm Simulator has 2.7K ratings behind it against 125, 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 18% of Critical's.

Swarm Simulator ships an update every 9 days, Critical fortnightly. The most recent releases landed on September 29, 2026 and September 22, 2026 respectively.
