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 update cadence: VoltLab at every 4 days against Circuit Simulator's every 6 weeks. VoltLab also leads on review sentiment (97% vs 73%) and rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model 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. VoltLab sells 7 in-app purchases, starting at $3.99 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.
VoltLab holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: VoltLab has 363 ratings behind it against 72, so its average is the more settled of the two. Written reviews point the same way: 97% of VoltLab's written reviews are positive against 73% of Circuit Simulator's.
VoltLab ships an update every 4 days, Circuit Simulator every 6 weeks. The most recent releases landed on September 21, 2026 and September 25, 2026 respectively.
