How should the effective value be calculated? What is the amplitude of the effective value of 100V? In such a case, do you have any experience of calculating the effective value while checking the calculation formula every time? This app can quickly convert the effective value and amplitude of AC waveforms. There are 4 types of conversion units: rms value, average value, amplitude, and Peak to Peak Amplitude. By inputting the amplitude or effective value of the AC waveform and selecting the unit of the input value, the value converted into 4 types of units will be displayed.

Verdict
The clearest difference is price: ProSITE at Free against RMS Calculator's $1.99. ProSITE also leads on update cadence (every 5 weeks vs every 15 months). RMS Calculator's advantage is iOS requirement (12.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
