Ohmulator vs DOE Triage
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Ohmulator
This electric circuit calculator simplifies Ohm's Law calculations. It allows users to input two known variables (current, resistance, voltage, or power) and automatically computes the unknown values. The app also supports on-the-fly unit adjustments, eliminating the need for manual conversions.
- Ohm's Law calculations
- Calculate unknown variables
- Adjustable unit types
- Total resistance calculator
- Supports Voltage, Current, Resistance, Power

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.
