# iCircuit vs Hydraulic schemes

The clearest difference is price: Hydraulic schemes at $0.99 against iCircuit's $12.99. Hydraulic schemes also leads on rating (5.0 vs 3.9) and review sentiment (77% vs 61%). iCircuit's advantage is ratings volume (154 vs 1) and chart position (#60 vs unranked). On update cadence, ads, in-app purchases and device support there is nothing between them.

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

Hydraulic schemes holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: iCircuit has 154 ratings behind it against 1, 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 77% of Hydraulic schemes's.

iCircuit ships an update every 4 weeks, Hydraulic schemes every 2 weeks. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
