Most circuit simulators show you numbers. EveryCircuit shows you electricity moving. That single difference is why 2.9 million circuits have been built on this platform and why universities around the world use it to teach electrical engineering.
EveryCircuit is an interactive circuit simulator available on the web, Android, and iOS that lets you design, simulate, share, and explore electronic circuits with real-time animated visualization. When you hit Play, you don’t just get data points — you see currents flowing through wires, voltages rising and falling as waveforms overlaid on the schematic, capacitors charging and discharging visually, and digital signals color-coded in real time.
Under the hood, it packs a custom-built simulation engine with proper numerical methods, realistic device models, and support for Ohm’s law, Kirchhoff’s voltage and current laws, and nonlinear semiconductor equations. But the genius of EveryCircuit is that all of that math becomes something you can see, touch, and interact with — especially on mobile, where you can literally draw input signals with your finger.
In a landscape where Multisim Live is shutting down in September 2026 and most simulators are either too complex for beginners or too limited for serious learning, EveryCircuit sits in a sweet spot that’s hard to match.
How EveryCircuit Works
The workflow is intentionally frictionless. Open the app (browser or mobile), start a new circuit, and you’ll see a clean black workspace with a ground symbol already placed. Components are listed in a toolbar at the top. Drag them into the workspace, and the automatic wire routing connects everything cleanly without manual trace drawing.
Once your circuit is wired, tap the Play button. Instantly, animations appear directly on the schematic. Analog signals show as mini waveforms riding on top of the wires. Constant DC voltages display as numbers at each node. Digital wires get color-coded by logic state. Current flow is visualized as moving dots. Everything updates in real time.
The real power emerges when you start interacting during simulation. You can rotate a potentiometer knob, flip a switch, ramp up an input voltage, or adjust a resistor value — and the circuit responds immediately. On mobile devices, you can even generate an arbitrary input signal by drawing it with your finger on the screen. This level of interactivity is something you won’t find in desktop SPICE tools like LTspice, Multisim, or PSpice.
Component Library
EveryCircuit covers both analog and digital electronics with a focused but comprehensive component set.
Passive components: resistors, capacitors (including polarized), inductors, potentiometers, transformers, and center-tapped transformers.
Semiconductors: diodes, Zener diodes, LEDs, RGB LEDs, NPN and PNP bipolar transistors, NMOS and PMOS transistors.
Logic gates: AND, OR, NOT, NAND, NOR, XOR, XNOR.
Latches and flip-flops: SR NOR latch, SR NAND latch, D flip-flop, T flip-flop, JK flip-flop.
Integrated circuits: 555 timer, counter, ADC, DAC, binary-to-7-segment decoder.
Sources: DC voltage and current sources, sinusoidal generator, pulse generator, binary source, and all four types of controlled sources (VCVS, CCVS, VCCS, CCCS).
Switches: SPST, SPDT, normally open and normally closed push buttons, relay.
Other: op-amp, 7-segment display, lamp, DC motor, voltmeter, ammeter, ohmmeter.
This library is broad enough to build everything from a basic voltage divider to complex transistor-level oscillators, mixed-signal designs, and digital counters with 7-segment displays.
Analysis Features That Go Beyond Eye Candy
EveryCircuit is often praised for its visuals, but its analysis capabilities deserve equal attention.
DC analysis: computes the operating point of your circuit in steady state. Essential for checking transistor biasing, amplifier quiescent points, and voltage divider outputs.
Transient analysis: time-domain simulation that drives the real-time animations. This is what runs when you press Play — the engine continuously solves the circuit equations and updates the visual output.
AC analysis with frequency sweep: generates Bode plots showing magnitude and phase response across frequency. Phases and magnitudes are displayed as circles on the schematic that change dynamically as you move along the frequency trace. This is invaluable for understanding filters, amplifiers, and resonant circuits.
I-V curve characteristics: you can step the gate voltage of a MOSFET transistor and obtain a family of I-V curves. The linear and saturation regions are visualized directly inside the MOSFET symbol on the schematic — a visual teaching tool that’s hard to replicate elsewhere.
Built-in oscilloscope: a virtual oscilloscope with XY mode for plotting any pair of time-domain signals against each other. The scale and grid ticks auto-update to convenient values as data changes, eliminating manual range adjustment.
Pricing: One Payment, Forever, Everywhere
EveryCircuit’s pricing model is refreshingly simple in a market dominated by subscriptions.
Free tier: download and use EveryCircuit at no cost. Your own circuits are limited to 5 components. However, you can explore and simulate any public community circuit (regardless of size) and access all simulation features. No ads.
$15, one-time payment, forever: a single purchase unlocks everything on all platforms (web, Android, iOS). No subscriptions, no recurring charges, no component limits, unlimited cloud storage, and cross-device sync. Buy on one platform, sign in on another, and it’s automatically unlocked.
Class license for educators — from $4 per student per semester: universities and schools can request a class license by specifying course dates and student count. Top universities worldwide already use EveryCircuit in their electrical engineering curricula.
Who Is EveryCircuit Built For?
Students Learning Circuits and Electronics
If you’re taking circuit theory, analog electronics, digital electronics, or any course where understanding component behavior matters, EveryCircuit turns abstract equations into visible, interactive experiences. Watching current actually flow through a voltage divider, seeing a capacitor charge in an RC circuit, or visually understanding MOSFET saturation regions — these are learning moments that no textbook can deliver.
The free version is enough to explore community circuits and grasp core concepts. For building your own designs, the $15 one-time payment is a fraction of what a textbook or a component kit costs.
Educators and Professors
The class license makes institutional adoption straightforward and affordable. Students access EveryCircuit from any device — including their phones, which is a significant advantage over browser-only or desktop-only tools. A professor can project a circuit, modify a parameter live, and the entire class watches the behavior change instantly.
The community gallery of 2.9 million circuits serves as a ready-made library of examples for assignments, demonstrations, and self-study resources.
Hobbyists, Makers, and Ham Radio Enthusiasts
For hobbyists who want to validate circuit ideas quickly, the real-time interactivity makes prototyping feel almost playful. Adjust a potentiometer, swap a capacitor value, try different transistor configurations — all without soldering or breadboarding anything.
The component set covers RF basics well enough (inductors, transformers, controlled sources, op-amps), and the AC analysis with Bode plots is directly useful for filter and amplifier design that ham radio enthusiasts frequently need.
Multisim Live Users Looking for Alternatives
With NI’s Multisim Live officially shutting down on September 15, 2026, thousands of users need a new browser-based simulator. EveryCircuit covers DC, AC, and transient analysis with a far more visual and intuitive interface than Multisim Live offered. For educational users who formed Multisim Live’s core audience, EveryCircuit is a strong replacement — especially with its mobile apps, which Multisim Live never had.
EveryCircuit vs. The Competition
EveryCircuit vs. Falstad (CircuitJS)
Falstad is the closest philosophical cousin to EveryCircuit: both animate current flow on schematics, and Falstad is completely free and open source.
The differences lie in polish and features. Falstad has a more technical, utilitarian interface. EveryCircuit offers automatic wire routing, native mobile apps, AC analysis with Bode plots, I-V curve generation, and a community gallery of millions of circuits. Falstad has no mobile app, no cloud storage, and no community features.
If you need completely free simulation with no limits, Falstad is excellent. If you value a refined experience, mobile access, and deeper analysis tools, EveryCircuit justifies its price.
EveryCircuit vs. Tinkercad Circuits
Tinkercad offers a 3D breadboard view with Arduino simulation — features EveryCircuit doesn’t have. Tinkercad is completely free and browser-only.
EveryCircuit offers a more powerful simulation engine for analog circuits (AC analysis, I-V curves, oscilloscope), real-time animated visualization, and native mobile apps. It doesn’t support Arduino or microcontrollers.
Choose Tinkercad if Arduino prototyping on a virtual breadboard is your priority. Choose EveryCircuit if understanding circuit behavior through animated visualization matters more.
EveryCircuit vs. CircuitLab
CircuitLab is a professional-grade schematic capture and SPICE simulation tool. It offers higher precision modeling, PDF/SVG schematic export, and an integrated interactive textbook.
CircuitLab operates on a subscription model and has no mobile app or animated visualizations. It’s more powerful for professional engineering work but less intuitive for learning.
EveryCircuit is better for visual learning and mobile access. CircuitLab is better for professional documentation and precision analysis.
EveryCircuit vs. Diode (withdiode.com)
Diode offers 3D breadboard simulation with Arduino support — a completely different experience. It’s free and browser-based.
EveryCircuit works in 2D schematic mode with animated visualization. No breadboard, no Arduino, but deeper signal analysis (AC, I-V curves, oscilloscope) and native mobile apps.
These tools are complementary rather than competitive. Use Diode to learn physical circuit assembly and Arduino programming. Use EveryCircuit to understand electrical behavior through animated visualization.
Getting Started: Quick Tutorial
Your First Circuit in EveryCircuit
Step 1: Go to everycircuit.com/app in your browser, or download the app on Android or iOS.
Step 2: Create a new circuit. A ground symbol appears by default — keep it. Every circuit needs a ground reference for simulation.
Step 3: Add a voltage source. Select “Voltage” from the component bar and place it on the workspace. Use the analog adjustment knob at the bottom to set it to 9V.
Step 4: Add a resistor. Place it in series and adjust to approximately 470Ω.
Step 5: Add an LED. Place it in series with the resistor.
Step 6: Connect everything. Tap component terminals to create wires. Automatic routing handles the trace layout.
Step 7: Hit Play. Current flows as animated dots through the circuit, the LED lights up, and voltage/current values appear at every node. Try adjusting the resistor value while the simulation runs and watch the LED brightness change in real time.
Strengths and Limitations
What EveryCircuit Does Best
The animated visualization is unmatched. No other simulator (except Falstad, partially) shows circuit behavior so intuitively. For students, this transforms understanding of concepts like capacitor charging, transistor switching, and LC resonance from abstract math to visible, tangible phenomena.
Cross-platform availability (web + Android + iOS) with native apps is a major advantage. Start a circuit on your lab computer, review it on the bus from your phone. Few simulators offer this with real native apps.
The one-time $15 payment with no subscription is a pricing model users genuinely appreciate. Pay once, own it forever, on every platform.
The community gallery of 2.9 million circuits is a massive educational resource. Search for virtually any circuit type, open it, and simulate it instantly.
Current Limitations
The free version’s 5-component limit is quite restrictive. Any practical circuit will require the paid version.
No microcontroller support (Arduino, ESP32, Raspberry Pi Pico). If you need to simulate code alongside hardware, you’ll need a separate tool.
The component library, while solid for basic and intermediate electronics, lacks some elements that advanced users request: antennas, speakers, variable capacitors, sensors, OLED displays.
The interface is English-only, though component names are universal in electronics.
The Verdict
EveryCircuit occupies a specific niche and executes on it exceptionally well: it’s the best circuit simulator for visually understanding how electronics work. Its real-time animations turn abstract equations into visual experiences that accelerate learning in ways no textbook or static simulator can match.
Use EveryCircuit if:
- You want to visually see current flow, capacitor charging, and circuit oscillation
- You need a circuit simulator on your phone (Android or iOS) with a native app
- You prefer a one-time payment over subscriptions
- You teach electronics and need a visual demonstration tool for class
- You want to explore thousands of community-designed circuits
Consider alternatives if:
- You need Arduino or microcontroller simulation (try Tinkercad, Wokwi, or Diode)
- You need professional SPICE analysis with schematic export (try CircuitLab or LTspice)
- You need PCB design capabilities (try EasyEDA or KiCad)
- You want completely free simulation with no component limits (try Falstad)
EveryCircuit doesn’t try to be everything. It tries to be the best tool for understanding circuits visually and interactively. And at that, it has no real rival.
