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 in-app purchases: Tenio at none against Circuit Simulator's 8. Tenio also leads on rating (5.0 vs 4.7). Circuit Simulator's advantage is ratings volume (93 vs 2) and update cadence (every 2 months vs every 4 months). On price, ads, device support and iOS requirement 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. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Tenio asks for nothing beyond the download.
Tenio holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Circuit Simulator has 93 ratings behind it against 2, so its average is the more settled of the two.
Circuit Simulator ships an update every 2 months, Tenio every 4 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
