# iCircuit vs Logic Kit

The clearest difference is rating: Logic Kit at 4.9 against iCircuit's 3.9. Logic Kit also leads on review sentiment (100% vs 61%) and in-app purchases (none vs 2). iCircuit's advantage is ratings volume (151 vs 9) and chart position (#90 vs unranked). On ads, monetization model and device support there is nothing between them.

iCircuit costs $12.99 and Logic Kit $9.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. Logic Kit asks for nothing beyond the download.

Logic Kit holds the better App Store score, 4.9 against 3.9. That said, the two scores are not equally well evidenced: iCircuit has 151 ratings behind it against 9, 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 100% of Logic Kit's.

iCircuit ships an update every 4 weeks, Logic Kit every 9 days. The most recent releases landed on November 10, 2026 and November 3, 2026 respectively.
