# iCircuit vs Circuit

The clearest difference is review sentiment: iCircuit at 61% against Circuit's 0%. iCircuit also leads on rating (3.8 vs 1.0) and ads (none vs shown). Circuit's advantage is price (Free vs $12.99) and in-app purchases (none vs 2). On update cadence and device support there is nothing between them.

Circuit is free to download; iCircuit costs $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. Circuit asks for nothing beyond the download.

iCircuit holds the better App Store score, 3.8 against 1.0. That said, the two scores are not equally well evidenced: iCircuit has 135 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 0% of Circuit's.

iCircuit ships an update every 4 weeks, Circuit every 5 weeks. The most recent releases landed on October 18, 2026 and October 12, 2026 respectively.
