RCircuitCalc vs Moku
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
RCircuitCalc
This app helps engineers and students design electrical and electronic circuits by calculating standard resistance values based on E-series numbers. It supports various circuit types, including voltage dividers, series, parallel, and combination circuits, and can also calculate current and power for each resistor.
- Calculates standard resistance values
- Supports voltage dividers, series, parallel, and combination circuits
- Calculates current and power for resistors
- Outputs resistance values based on E-series numbers (E6, E12, E24, E48, E96)
- Calculations based on input voltage, output voltage, current, and resistance ratio

This application is intend for engineers and students who are wasting time for designing electric and electronic circuits. The standard resistance values based on E-series numbers are outputted in inputting necessary conditions such as input voltage, output voltage, current and so on. Features The calculable circuits are as follows: - Voltage Dividers (Inputting output voltage or resistance ratio) - Series Circuits - Parallel Circuits - Combination Circuits In the Voltage Dividers, resistance values are calculated in entering input voltage, output voltage or resistance ratio, and current into input boxes, besides, the most suitable resistance values are calculated in selecting priority whether Normal or Vout. In the Series Circuits, Parallel Circuits and Combination Circuits, divided resistance values are calculated in entering a combined resistance value into an input box. Calculated resistance values are displayed with the following E-series number specified either. E6, E12, E24, E48, E96 This application is able to calculate current and power of each resistor on calculated resistance values. Attention Because standard resistors are used and precision of calculation is ensured, the following restrictions are set up. - Range of resistance value: 1Ω ~ 10MΩ - Range of resistance ratio: 0.1 ~ 10

Verdict
The clearest difference is review sentiment: Moku at 50% against RCircuitCalc's 0%. Moku also leads on price (Free vs $1.99) and rating (5.0 vs 1.0). RCircuitCalc's advantage is device support (3 vs 1) and iOS requirement (13.6 vs 15.0). On ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Moku is free to download; RCircuitCalc costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Moku holds the better App Store score, 5.0 against 1.0. Both are backed by a comparable volume of ratings — 5 and 6 respectively. Written reviews point the same way: 0% of RCircuitCalc's written reviews are positive against 50% of Moku's.
RCircuitCalc ships an update every 17 months, Moku every 2 months. The most recent releases landed on October 2, 2026 and October 3, 2026 respectively.
