# Electrical Calculations vs Hydraulic schemes

The clearest difference is price: Electrical Calculations at Free against Hydraulic schemes's $0.99. Electrical Calculations also leads on ratings volume (129 vs 1) and review sentiment (87% vs 77%). Hydraulic schemes's advantage is ads (none vs shown) and rating (5.0 vs 4.6). On update cadence, in-app purchases, monetization model and device support there is nothing between them.

Electrical Calculations is free to download; Hydraulic schemes costs $0.99 up front. Electrical Calculations sells 2 in-app purchases, starting at $3.99 per 3 months 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 4.6. That said, the two scores are not equally well evidenced: Electrical Calculations has 129 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 87% of Electrical Calculations's written reviews are positive against 77% of Hydraulic schemes's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
