Build a circuit. See current flow. Understand how it works. Electro Sim turns electronics into something you can explore on your iPhone or iPad. Place components, connect wires, and run a simulation to see how your circuit responds. Whether you are learning the basics, preparing a classroom demonstration, or testing an idea, start with a working example or build your own. BUILD ON A CANVAS OR A BREADBOARD Create schematic circuits with drag-and-drop components and flexible wiring, or try a virtual breadboard with components and jumper wires. Zoom in to make connections, rotate parts, and use undo and redo as you experiment. SEE WHAT CHANGES WHEN YOU CHANGE THE CIRCUIT Follow animated current flow, inspect voltage and current readings, and use a virtual multimeter to explore circuit behavior. Adjust component values, toggle switches, or advance the simulation one step at a time to connect cause and effect. LEARN THROUGH WORKING EXAMPLES Explore LED circuits, capacitor charging, logic gates, adders, counters, seven-segment displays, and traffic lights. Selected examples include guided steps that help you investigate the circuit and check your understanding. FIND THE PARTS YOU NEED Browse a searchable component library with resistors, capacitors, inductors, diodes, LEDs, transistors, switches, buzzers, logic gates, and signal sources. Component descriptions and pin information help you decide what to use and how to connect it. TURN CIRCUIT BLOCKS INTO REUSABLE MODULES With Pro, create custom components from circuit blocks, define their pins, and reuse them in new projects. Build up a collection of modules as your ideas grow. Custom component creation and use require an active Pro subscription. SAVE AND SHARE YOUR WORK Save projects to revisit later, exchange circuit files in JSON format, and export circuit snapshots or PDF reports with readings and notes for learning and discussion. Designed for iPhone and iPad, with light and dark appearances and English, Simplified Chinese, and Traditional Chinese interfaces. Start with one LED, then see where your curiosity takes you.

Verdict
The clearest difference is review sentiment: Electro Sim at 100% against Smart Logic Simulator's 50%. Electro Sim also leads on rating (4.0 vs 3.7). Smart Logic Simulator's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 2 months vs every 4 months). On price, 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
Both are free to download. Smart Logic Simulator sells 1 one-off in-app purchase and Electro Sim sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Electro Sim holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews point the same way: 50% of Smart Logic Simulator's written reviews are positive against 100% of Electro Sim's.
Smart Logic Simulator ships an update every 2 months, Electro Sim every 4 months. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
