# Circuit Simulator vs Singular

The clearest difference is rating: Circuit Simulator at 4.7 against Singular's 1.0. Circuit Simulator also leads on ads (none vs shown) and ratings volume (72 vs 1). Singular's advantage is update cadence (daily vs every 6 weeks). On price, in-app purchases, monetization model 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 and Singular sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Circuit Simulator holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Circuit Simulator has 72 ratings behind it against 1, so its average is the more settled of the two.

Circuit Simulator ships an update every 6 weeks, Singular daily. The most recent releases landed on September 25, 2026 and August 25, 2026 respectively.
