“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.

Verdict
The clearest difference is rating: PhysicsCalc at 5.0 against AR Circuits 4D | Physics's 3.8. AR Circuits 4D | Physics's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 3 months). 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. PhysicsCalc sells 1 one-off in-app purchase. AR Circuits 4D | Physics asks for nothing beyond the download.
PhysicsCalc holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: AR Circuits 4D | Physics has 10 ratings behind it against 1, so its average is the more settled of the two.
AR Circuits 4D | Physics ships an update every 3 weeks, PhysicsCalc every 3 months. Both last shipped on October 2, 2026.
