Description This is the BEST app to learn about Resistors and Circuit Resistance (Equivalent Resistance). This virtual lab provides an excellent environment for anyone who is interested in understanding series and parallel resistors, learning how to measure voltages across resistors, current through series and parallel circuits and solving simple circuits. Features - VERY SIMPLE and EASY TO USE, with up to eight component sections. - Component sections can easily be configured from five different types. - VIRTUAL "Hands On" experience using volt and amp meters. - Resistor values can easily be changed with a picker, keypad or using randomize button. - Circuit voltage can easily be changed from 1 to 1000 volts with a picker or a keypad. - The "Basics" screen make this app unique for the simplicity and speed of seeing the effects of "Opens" (resistor component with infinite resistance) and "Shorts" (resistor component with zero resistance). - FREE and NO ADVERTISEMENTS. - The circuit is always "LIVE" and immediately shows voltage, current and circuit resistance with any changes made to the circuit.

Verdict
The clearest difference is rating: Simple Circuit Builder at 4.0 against AI Resistor Color Code Scanner's 3.0. Simple Circuit Builder also leads on in-app purchases (none vs 1) and ratings volume (28 vs 1). On price, update cadence and ads 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
Both are free to download. AI Resistor Color Code Scanner sells 1 one-off in-app purchase. Simple Circuit Builder asks for nothing beyond the download.
Simple Circuit Builder holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: Simple Circuit Builder has 28 ratings behind it against 1, so its average is the more settled of the two.
Simple Circuit Builder ships an update every 3 weeks, AI Resistor Color Code Scanner every 5 weeks. The most recent releases landed on October 1, 2026 and October 5, 2026 respectively.
