# iCircuit vs ARK

The clearest difference is price: ARK at Free against iCircuit's $12.99. ARK also leads on rating (4.6 vs 3.9) and in-app purchases (none vs 2). iCircuit's advantage is ratings volume (154 vs 11) and chart position (#198 vs unranked). On update cadence, ads and device support there is nothing between them.

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

ARK holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: iCircuit has 154 ratings behind it against 11, 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 83% of ARK's.

iCircuit ships an update every 4 weeks, ARK fortnightly. The most recent releases landed on November 10, 2026 and November 4, 2026 respectively.
