# Easy Ohm's Law vs Electronics Tools & Calculator

The clearest difference is review sentiment: Easy Ohm's Law at 69% against Electronics Tools & Calculator's 17%. Easy Ohm's Law also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.0). Electronics Tools & Calculator's advantage is rating (4.0 vs 1.5) and in-app purchases (none vs 1). On price, update cadence and device support there is nothing between them.

Both are free to download. Easy Ohm's Law sells 1 one-off in-app purchase. Electronics Tools & Calculator asks for nothing beyond the download.

Electronics Tools & Calculator holds the better App Store score, 4.0 against 1.5.
