# Circuit Simulator vs UPDS

The clearest difference is in-app purchases: UPDS at none against Circuit Simulator's 8. UPDS also leads on iOS requirement (12.0 vs 15.3). Circuit Simulator's advantage is ratings volume (93 vs 3). On price, rating, ads and device support there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. UPDS asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Circuit Simulator against 4.7 for UPDS. That said, the two scores are not equally well evidenced: Circuit Simulator has 93 ratings behind it against 3, so its average is the more settled of the two.
