VoltSim is a realtime electronic circuit simulator like Multisim, SPICE, LTspice, Altium or Proto for circuit design with a better user experience. VoltSim is a complete circuit app in which you can design circuits with various components and simulate an electric or digital circuit. During simulation you can check voltage, current and many other variables. Check signals on multichannel oscilloscope or multimeter and tune your circuit in real time! You can also use VoltSim as logic circuit simulator and perform digital electronic analysis! This app will help you visualize how the voltage varies across the circuit and how current flows through it. T&C: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ads: Circuit Simulator at none against Electronic Devices Quiz's shown. Electronic Devices Quiz's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (12.0 vs 15.3). On price, in-app purchases and device support 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. Electronic Devices Quiz sells 7 in-app purchases, starting at $4.99 per month and Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Electronic Devices Quiz ships an update every 3 weeks, Circuit Simulator every 2 months. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
