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 circuit simulation tools for PC.

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.

2. Electric Circuit Studio

Download the App on the Google Store by clicking this Button
“This is a free version, which contains ads. The “PRO” version without ads is named “ECStudio”. The full documentation is available at ecstudiosystems.com/help
There you can see that labels (grey border boxes) can be moved and switches can be switched using long tapping, etc. We also recommend to view the Screencast Tutorial on our YouTube channel.

Electric Circuit Studio is a set of tools used for building electronic circuits, SPICE simulation, and calculation of circuits. These tools are complemented by the information center containing resources, connector pinouts and short interactive book explaining basic electrical theorems, laws and circuits. It is a useful application for all electronics hobbyists, students, or other people with an interest in electronics.

• Schematic editor and SPICE simulator
These tools allow easy creation of circuit diagrams and SPICE analysis of the created circuits. The simulator is focused on visual representation of simulated results, such that simulated voltages and currents can be placed elsewhere in the circuit, as a text or graph. Moreover, the magnitude and polarity of voltages and currents can be represented by visual indicators, so you can check the results quickly. All results can be additionally displayed on the top plot, where they can be explored using two cursors.

DC, AC and Transient analyses are supported.

The simulation can be run repeatedly (in Transient analysis) and results can be displayed consecutively with a user controlled speed (in all analysis types), or all simulation results are displayed immediately. When the results are shown consecutively, you can control parameters of circuit elements by the seek bar and see the change of results in real time.

In AC analysis, you can display the magnitude, real value, imaginary value and phase of voltages and currents.

The schematic editor supports undo and redo and also working with several selected elements. All elements except wires allow proper rotation and flipping of the text inside elements.

Supported elements: wire, ground, resistor, capacitor, polarized capacitor, inductor, DC voltage source, pulse source, sinusoidal source, DC current source, text, picture, diode, zener diode, LED, transistors (NPN, PNP, NMOS, PMOS, NJFET, PJFET), logic gates (NOT, AND, NAND, OR, NOR, XOR, XNOR), SR latch, D flip-flop, T flip-flop, JK flip-flop, operational amplifier, 555 timer, LM317, LM337, 7805, 7905, VCVS, VCCS, CCVS, CCCS, potentiometer, transformer, switch SPST, switch SPDT, open push-button, closed push-button, relay SPST, relay SPDT, crossover.

Screenshots and exporting the whole circuit are also supported.
Wires are drawn using autorouting or they can be drawn manually using single-segment lines.

3. Droid Tesla Demo

Download the App on the Google Store by clicking this Button
“This is a demo version for Droid Tesla Pro!

Droid Tesla is a simple and powerful circuit simulator.

Perfect for students new to electronics circuit design and construction,
hobbyist and tinkerers and even seasoned professionals who want a quick,
handy tool to perform electronics circuit design calculations.

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).

DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL)
in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance
with KCL and then proceeds to solve for the unknown quantities using various algebraic
techniques such as Gaussian elimination and sparse matrix techniques.

For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer
and then improving the solution with successive calculations built upon this guess.
This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithm
to solve circuits with non-linear I/V relationships.

For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time.
DroidTesla offers the Trapezoidal(I’ll add a GEAR method later) integration methods to approximate the state of the reactive elements.
Although for most circuits, both methods will provide almost identical results,
it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.

DroidTesla for now can simulate:
-Resistor
-Capacitor
-Inductor
-Potentiometer (available only in pro version)
-Light Bulb (available only in pro version)
