# Circuit Simulator vs Microelectronics

The clearest difference is ratings volume: Circuit Simulator at 93 against Microelectronics's 1. Circuit Simulator also leads on device support (3 vs 1) and iOS requirement (15.3 vs 17.0). Microelectronics's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month and Microelectronics sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Microelectronics holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Circuit Simulator has 93 ratings behind it against 1, so its average is the more settled of the two.

Circuit Simulator ships an update every 2 months, Microelectronics every 3 months. The most recent releases landed on October 30, 2026 and October 21, 2026 respectively.
