Makes Ohm's Law simple! Ohmulator is a simple, yet robust, electric circuit calculator that enables you to quickly find the unknown variables of a circuit. Ohmulator allows you to easily adjust unit types on the fly (eg. milli Amps, Amps, kilo Amps), which means no prior conversion! Enter two known variables (from: I = Current, R = Resistance, V = Voltage, P = Power), set preferred units, then Ohmulator will calculate and return the previously unknown values. Also an effective (total) resistance calculator. What two App Store reviewers had to say about Ohmulator: "Great. Does what it says. Very good app. Stylish design." 5 Stars - Jamie1990jamie "Awesome app. It simply works. A must have for the radioamateur or electronic nerd. Nice to have the watt law as well." 5 Stars - Per67 Also available for macOS on the Mac App Store.

Verdict
The clearest difference is price: FeasyLEA at Free against Ohmulator's $0.99. FeasyLEA also leads on update cadence (every 2 weeks vs every 2 months). Ohmulator's advantage is rating (4.7 vs 2.0) and ratings volume (79 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.
