"AR Circuits 4D Physics" is an educational application designed by Valeriy Danyuk to teach children how to create and explore circuit boards using augmented reality technology. The app allows users to design circuit boards without the need for physical components, eliminating safety concerns and costs associated with traditional circuit building. By arranging printed paper component cards and utilizing the device camera, users can create sequential, parallel, and combined circuits. The app provides a variety of components including batteries, switches, light bulbs, resistors, electric motors, and more, allowing users to measure voltage, current intensity, and control resistances.

The technical requirements for the app include a tablet or smartphone with a camera, a minimum of 700 MB of free space, 1 GB of RAM, and iOSor higher. Additionally, the app offers an auto-renewing subscription-based in-app purchase called "Metodist's mode" for $2.00 (USD) per month. Users can manage their subscriptions through their iTunes Account Settings.
