“AR Danik Circuit Engineering” will help your child to learn how to create and explore various circuit boards with the use of augmented reality technology. App allows you to create boards without costs, safety problems and inconveniences with electric components. The circuits are designed by arranging printed paper component cards and pointing the mobile device camera from the application. At the moment list of electrical circuit components includes: one battery, two switches, six incandescent light bulbs, four resistors, one electric motor, testing component for conductors and dielectrics, six wires and earthing. These components allow to set up sequential, parallel and combined boards. Voltage and current intensity of every circuit can be measured with voltmeter and ammeter. Besides, resistances of light bulbs, resistors and electric motor are controllable; battery has 4 alternative voltages. Attention! Technical requirements for devices: tablet or smartphone with camera, min. 700 mb of free space, 1 GB RAM, iOS 9.3.5 and higher.

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 rating: Circuit Simulator at 4.7 against AR Circuits 4D | Physics's 3.8. Circuit Simulator also leads on ratings volume (93 vs 10). AR Circuits 4D | Physics's advantage is in-app purchases (none vs 8) and review sentiment (100% vs 77%). On price, ads, monetization model 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. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. AR Circuits 4D | Physics asks for nothing beyond the download.
Circuit Simulator holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Circuit Simulator has 93 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 100% of AR Circuits 4D | Physics's written reviews are positive against 77% of Circuit Simulator's, so the app with the better star average is not the one people write more warmly about.
AR Circuits 4D | Physics ships an update every 3 weeks, Circuit Simulator every 2 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
