All joking aside, this time you will understand how electronic circuits work.

Build any circuit, tap play button, and watch dynamic voltage, current, and charge animations. This gives you insight into circuit operation like no equation does.

While simulation is running, adjust circuit parameters with analog knob, and the circuit responds to your actions in real time. You can even generate an arbitrary input signal with your finger!

That’s interactivity and innovation you can’t find in best SPICE tools for PC like Multisim, LTspice, OrCad or PSpice (trademarks belong to their respective owners).

EveryCircuit is not just an eye candy. Under the hood it packs custom-built simulation engine optimized for interactive mobile use, serious numerical methods, and realistic device models. In short, Ohm’s law, Kirchhoff’s current and voltage laws, nonlinear semiconductor device equations, and all the good stuff is there.

Growing library of components gives you freedom to design any analog or digital circuit from a simple voltage divider to transistor-level masterpiece.

Schematic editor features automatic wire routing, and minimalistic user interface. No nonsense, less tapping, more productivity.

Simplicity, innovation, and power, combined with mobility, make EveryCircuit a must-have companion for high school science and physics students, electrical engineering college students, breadboard and printed circuit board (PCB) enthusiasts, and ham radio hobbyists.

Free version has limited sandbox area, but it can still impress you. If you need a larger playground, a full version is available. The full version will employ all of your imagination, and all the screen area of your tablet.

Thanks to Prof. N. Maghari for technical discussions, feedback, and help with designing circuit examples.

***** Higher Lower *****

Develop your skill to recognize different pitches.

Given 2 notes, can you identify whether the second note is higher or lower in pitch than the first note? A beginners exercise. You can make the exercise more difficult by restricting the range of the 2 notes played.

***** Pitch Training *****

Given a single note, can you play it back? This exercise allows your to zoom in on the note using relative pitch skills, and will record how many notes it takes for you to correctly identify. Make this more difficult by setting a time interval between listening and playing.

***** Interval Training *****

Given 2 notes, do you know how far apart they are? Being able to determine intervals between notes in the key skill to playing by ear.

You can change the base note to interval train in any key.

This is made easy as it associates an interval (e.g. Minor 2nd, Major 2nd, Minor 3rd, etc.) with a well known song. Select Song Clue to use a well known song as a learning aid to identify the intervals by ear.

***** Chord Distinction *****

Can you distinguish a Major from a Minor for example?

100s of chords.

Select arpeggio mode to make chord distinction easier.

Select highlight to inspect the construction of the chords.

You can change the key of the chord.

Work your way through the levels.

Breakdown of chords listed on Help page.

***** Interval Comparison *****

Given 2 intervals, can you determine whether the second interval is wider or narrower in distance?

***** Pitch Identification *****

A popular test that comes up in music grade aural exams. Given a chord can you identify a specific note/pitch within it? For example, given a C Major chord, can you find the highest note?

***** Melodic Dictation *****

Given a melody, can you play it back?

***** Chord Progression *****

Can you distinguish a I – IV – V – I progression from a I – V- IV – I? Contains all the most common chord progressions which you will find in nearly all the most popular songs.

***** Scale Identification *****

Given a scale, can you identify it as a Major scale, Harmonic Minor or Natural Minor for example?
