V aplikaci Motion Start si sami vyzkoušíte, jak snadné je propojení auta se službou Chytré auto. Aplikace Motion Start simuluje zapojení zařízení Chytré auto do OBD portu, přihlášení do aplikace Motion a následně použití služby Chytré auto při jízdě, to všechno pomocí virtuální reality. Pro spuštění aplikace použijte brýle pro virtuální realitu (např. cardboard).
iCircuit 3D
Design, build, and test electronic circuits in a realistic 3D environment. This app offers a virtual workbench with over 150 simulated parts and tools to experiment with circuits, diagnose issues, and visualize component behavior.
- 3D virtual workbench
- Real-time circuit simulation
- 150+ physically simulated parts
- Realistic component behavior
- Magic smoke failure simulation
- Import custom 3D models
- Symbolic component library

iCircuit 3D gives you an endless virtual workbench to design, build, and test electronics projects in 3D. It combines the robust real-time, always-on simulation engine of iCircuit with modern 3D rendering and physics on iOS and macOS. Do not let the availability of physical parts limit your creativity. Choose from an expansive library of 150+ physically and electronically simulated parts and over 1,000 reference boards to plan layouts, wire circuits, test ideas, and iterate fast. It also includes the full standard component library from the original iCircuit, so you can switch between realistic parts and symbolic circuit elements whenever you want. When powered, LEDs light up realistically, DC motors spin, and speakers make noise. Watch current flow along your simulated wires. See pinouts and color codes directly on components. Tap any part to view live values like voltage and current, then change parameters instantly. If you miswire something or overstress a component, magic smoke will billow from the point of failure so you can quickly diagnose and fix the problem. Add reference photos to the environment, import your own 3D models to mount projects onto, or use Blocks to build enclosures, panels, and simple structures. FEATURES • Tons of resistors, capacitors, and LEDs • Multiple breadboards and wiring elements • Diodes, BJTs, MOSFETs • DC power supplies • Waveform generators (AC, square, sawtooth) • Batteries (AA, AAA, 18650, coin cells, and more) • Switches (SPST, SPDT) • Buzzers and speakers • DC motors and servos • Programmable Arduino elements • The full symbolic iCircuit library (standard components included) • 1,000+ reference circuit boards for layout planning (not fully simulated) • Import board layouts from Eagle (imported layouts are for wiring/layout reference and do not simulate) • Import custom 3D models to attach your projects to, and simulate their behavior on the workbench • Import images for reference or documentation and place them as physical photographs HOW IT WORKS Add parts to the 3D workbench and they land on the table with gravity. Drag parts around, then draw wires between ports to connect them. When a circuit is completed, it starts simulating immediately. Wires stay connected as you move parts, so you can build tidy panels and enclosures, or leave parts scattered like a real bench. iCircuit 3D was designed for fun and exploration, with plenty more to discover as you build. I hope you enjoy this new take on circuit software.

Verdict
The clearest difference is price: Motion Start at Free against iCircuit 3D's $12.99. Motion Start also leads on rating (5.0 vs 4.1) and update cadence (monthly vs every 8 months). iCircuit 3D's advantage is ratings volume (72 vs 1). On ads, in-app purchases 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
Motion Start is free to download; iCircuit 3D costs $12.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Motion Start holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: iCircuit 3D has 72 ratings behind it against 1, so its average is the more settled of the two.
Motion Start ships an update monthly, iCircuit 3D every 8 months. The most recent releases landed on October 7, 2026 and October 14, 2026 respectively.
