The CircuitDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse, simplify and solve electrical circuits. You can design, draw, solve and simplify resistor-network, solve capacitor-network, solve inductor-circuit. You can design, draw, solve and simplify parallell circuit diagrams, series circuit diagrams, delta/wye circuit diagrams and any combinations of these. You can convert delta to wye and wye - delta network You can convert current source to voltage source or voltage source to current source You can design your own resistor (3,4,5 or 6 band resistor) or find the value for existing resistor You can even share your creativity with other people. Save the diagram locally. Do you have a complex network involving any combinations of parallell network, series network, delta/wye network? Fantastic. You can simplify this network and see how its done step by step so you can learn how to simplify networks. You can go back all the way to original network to see how the simplification was done. Simply stated, view simplification steps graphically. Keeps the historical diagram so that you can go back and verify each step. You can also share the simplification steps or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort of drawing diagrams and simplifying/solving it will not be lost. Are you a high school student learning electricity? This is the app for you. Are you a university student learning electrical engineering? This is the app for you. There is also a page to help you study. This study tab teaches you some very important laws of electricity and important formula. Like Ohm, law, Kirchhoff's volgate law, Kirchhoff's current law, There is also a page to help you learn now to use this app. This is a perfect app for a creative smart individual like you. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

VoltSim is a realtime electronic circuit simulator like Multisim, SPICE, LTspice, Altium or Proto for circuit design with a better user experience. VoltSim is a complete circuit app in which you can design circuits with various components and simulate an electric or digital circuit. During simulation you can check voltage, current and many other variables. Check signals on multichannel oscilloscope or multimeter and tune your circuit in real time! You can also use VoltSim as logic circuit simulator and perform digital electronic analysis! This app will help you visualize how the voltage varies across the circuit and how current flows through it. T&C: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
