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…
