# VoltLab vs Hydraulic Circuit Simulator

The clearest difference is rating: VoltLab at 5.0 against Hydraulic Circuit Simulator's 1.0. VoltLab also leads on ratings volume (363 vs 1). Hydraulic Circuit Simulator's advantage is iOS requirement (13.2 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. VoltLab sells 7 in-app purchases, starting at $3.99 per month and Hydraulic Circuit Simulator sells 1 in-app purchase, starting at $8.49 per year. Whichever you choose, the download price is not the number that matters.

VoltLab holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: VoltLab has 363 ratings behind it against 1, so its average is the more settled of the two.
