# Electrical Calculator vs Ohm's Law+

The clearest difference is update cadence: Ohm's Law+ at daily against Electrical Calculator's every 4 months. Ohm's Law+ also leads on rating (5.0 vs 4.6) and price ($0.99 vs $3.99). Electrical Calculator's advantage is ratings volume (462 vs 2) and iOS requirement (17.6 vs 26.0). On ads, in-app purchases and device support there is nothing between them.

Electrical Calculator costs $3.99 and Ohm's Law+ $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Ohm's Law+ holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrical Calculator has 462 ratings behind it against 2, so its average is the more settled of the two.

Electrical Calculator ships an update every 4 months, Ohm's Law+ daily. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
