# VoltLab vs Circuit Simulator

The clearest difference is update cadence: VoltLab at every 4 days against Circuit Simulator's every 6 weeks. VoltLab also leads on review sentiment (97% vs 73%) and rating (5.0 vs 4.7). 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 Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

VoltLab holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: VoltLab has 363 ratings behind it against 72, so its average is the more settled of the two. Written reviews point the same way: 97% of VoltLab's written reviews are positive against 73% of Circuit Simulator's.

VoltLab ships an update every 4 days, Circuit Simulator every 6 weeks. The most recent releases landed on September 21, 2026 and September 25, 2026 respectively.
