# Electrical Calculations vs Math Derivatives

The clearest difference is ads: Math Derivatives at none against Electrical Calculations's shown. Math Derivatives also leads on review sentiment (100% vs 87%) and iOS requirement (11.3 vs 15.0). Electrical Calculations's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (128 vs 15). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Electrical Calculations sells 3 in-app purchases, starting at $3.99 per 3 months and Math Derivatives sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Electrical Calculations against 4.5 for Math Derivatives. That said, the two scores are not equally well evidenced: Electrical Calculations has 128 ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 87% of Electrical Calculations's written reviews are positive against 100% of Math Derivatives's.

Electrical Calculations ships an update every 3 weeks, Math Derivatives every 2 months. Both last shipped on October 15, 2026.
