# iCircuit vs Sketch Simply

The clearest difference is price: Sketch Simply at $0.99 against iCircuit's $12.99. Sketch Simply also leads on update cadence (every 11 days vs every 4 weeks). iCircuit's advantage is rating (3.9 vs 3.6) and ratings volume (146 vs 5). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

iCircuit costs $12.99 and Sketch Simply $0.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month and Sketch Simply sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

iCircuit holds the better App Store score, 3.9 against 3.6. That said, the two scores are not equally well evidenced: iCircuit has 146 ratings behind it against 5, 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 50% of Sketch Simply's.

iCircuit ships an update every 4 weeks, Sketch Simply every 11 days. The most recent releases landed on November 1, 2026 and October 18, 2026 respectively.
