# Electrical Calc vs Mysa

The clearest difference is review sentiment: Electrical Calc at 89% against Mysa's 30%. Electrical Calc also leads on iOS requirement (8.0 vs 15.1). Mysa's advantage is price (Free vs $19.99) and rating (3.8 vs 2.5). On update cadence, ads, in-app purchases and device support there is nothing between them.

Mysa is free to download; Electrical Calc costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Mysa holds the better App Store score, 3.8 against 2.5. That said, the two scores are not equally well evidenced: Mysa has 572 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 89% of Electrical Calc's written reviews are positive against 30% of Mysa's, so the app with the better star average is not the one people write more warmly about.

Electrical Calc ships an update every 5 weeks, Mysa every 4 weeks. Both last shipped on October 13, 2026.
