# iCircuit vs Logic

The clearest difference is price: Logic at Free against iCircuit's $12.99. Logic also leads on in-app purchases (none vs 2). iCircuit's advantage is review sentiment (61% vs 21%) and ads (none vs shown). On rating, update cadence and device support there is nothing between them.

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

iCircuit holds the better App Store score, 3.8 against 3.6. That said, the two scores are not equally well evidenced: iCircuit has 135 ratings behind it against 7, 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 21% of Logic's.

iCircuit ships an update every 4 weeks, Logic every 5 weeks. The most recent releases landed on October 19, 2026 and October 12, 2026 respectively.
