# Faraday's Law Calculator vs DC Electric Generator

The clearest difference is price: DC Electric Generator at Free against Faraday's Law Calculator's $2.99. DC Electric Generator also leads on rating (5.0 vs 4.0) and update cadence (every 5 days vs every 26 months). Faraday's Law Calculator's advantage is ads (none vs shown) and iOS requirement (13 vs 16.0). On in-app purchases and device support there is nothing between them.

DC Electric Generator is free to download; Faraday's Law Calculator costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

DC Electric Generator holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: DC Electric Generator has 5 ratings behind it against 1, so its average is the more settled of the two.

Faraday's Law Calculator ships an update every 26 months, DC Electric Generator every 5 days. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
