Welcome to Circuitry - the world's first and only 3D circuit builder! INSANELY FAST Circuitry uses an optimized, GPU-accelerated network analysis algorithm that will blow your mind. It can calculate the voltages and currents of even the largest circuits in the blink of an eye - an insanely fast blinking eye! SUPER DUPER EASY TO USE While most circuit simulators are stuck in the stone age when it comes to usability, Circuitry takes you on a time-travel journey to the future. Its' 3D interface and intuitive controls will instantly feel familiar - no lengthy tutorials required. DOCUMENT-BASED Every circuit you build in Circuitry is a file. That way, they integrate perfectly into your existing files and can be used exactly the same way: you can duplicate and modify them, share them, and they are available to you on all your devices. HOW TO USE: 1. Place components by dragging from the toolkit to the canvas. 2. Connect components by tapping the sides of the components in cabling mode. 3. Delete or modify components by long pressing on them. AVAILABLE COMPONENTS: - Resistor - Voltage source - Light bulb

Avionics Pro contains virtually every tool needed to quickly solve homework problems and preview electronic lab experiments for the student who is completing a course of study to become an Aircraft Electronics Technician (AET). Specifically, it emphasizes Introductory Aircraft Avionics, featuring real world circuits that have been tested using an industry standard circuit simulator (Multisim) as well as in an actual electronics lab environment. Beyond the AET course, Avionics Pro is a handy refresher for graduate technicians in the industry as well as students looking to expand their understanding through higher education engineering courses. Avionics Pro features graphics support for all standard Apple phones and iPads.

Verdict

The call

The clearest difference is review sentiment: Avionics Pro at 100% against Circuitry's 51%. Avionics Pro also leads on rating (5.0 vs 3.9). Circuitry's advantage is ratings volume (155 vs 2) and iOS requirement (12.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.
