# iCircuit vs Circuitry

The clearest difference is price: Circuitry at Free against iCircuit's $12.99. Circuitry also leads on in-app purchases (none vs 2). iCircuit's advantage is update cadence (every 4 weeks vs every 4 months) and review sentiment (61% vs 51%). On rating, ratings volume, ads and device support there is nothing between them.

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

On the App Store both sit at effectively the same score — 3.8 for iCircuit against 3.9 for Circuitry. Both are backed by a comparable volume of ratings — 135 and 155 respectively. Written reviews are what separate them: 61% of iCircuit's written reviews are positive against 51% of Circuitry's.

iCircuit ships an update every 4 weeks, Circuitry every 4 months. The most recent releases landed on October 19, 2026 and October 17, 2026 respectively.
