# iCircuit vs Calctronics

The clearest difference is review sentiment: iCircuit at 61% against Calctronics's 14%. iCircuit also leads on ads (none vs shown) and ratings volume (134 vs 5). Calctronics's advantage is price (Free vs $12.99) and rating (4.0 vs 3.8). On in-app purchases, device support and iOS requirement there is nothing between them.

Calctronics is free to download; iCircuit costs $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month and Calctronics sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calctronics holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: iCircuit has 134 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 61% of iCircuit's written reviews are positive against 14% of Calctronics's, so the app with the better star average is not the one people write more warmly about.

iCircuit ships an update every 3 weeks, Calctronics every 2 months. The most recent releases landed on September 24, 2026 and September 9, 2026 respectively.
