# Electronics Toolkit! vs Circuit Simulator

The clearest difference is ads: Circuit Simulator at none against Electronics Toolkit!'s shown. Circuit Simulator also leads on review sentiment (73% vs 38%) and rating (4.7 vs 4.3). Electronics Toolkit!'s advantage is ratings volume (556 vs 72) and iOS requirement (11.0 vs 15.3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Electronics Toolkit! sells 1 one-off in-app purchase 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.

Circuit Simulator holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Electronics Toolkit! has 556 ratings behind it against 72, so its average is the more settled of the two. Written reviews point the same way: 38% of Electronics Toolkit!'s written reviews are positive against 73% of Circuit Simulator's.

Electronics Toolkit! ships an update every 2 months, Circuit Simulator every 6 weeks. The most recent releases landed on September 18, 2026 and September 20, 2026 respectively.
