About this app

Cirqlite is an offline circuit simulator and schematic editor built for students, engineers, and electronics enthusiasts. Draw electrical circuits on a clean, easy canvas, then run DC operating-point analysis, AC frequency sweep, and time-domain transient simulation using a real modified nodal analysis (MNA) engine based on fundamental circuit theory.

Whether you are studying the basics of ohms, voltage, and current, verifying a design before building it, or learning how op-amps, transistors, and digital logic work, Cirqlite gives you one practical workspace for all of it.

Key features:
- Comprehensive component library: resistors, capacitors, inductors, switches, DC voltage sources and AC sources with multiple waveforms (sine, square, triangle, pulse), diodes, LEDs, BJT transistors, MOSFET transistors, operational amplifiers (Op-Amp), digital logic gates (AND, OR, NOT), voltmeter, ammeter, transformer, potentiometer, and ground.
- Three simulation modes: DC operating point, AC sweep, and transient analysis with precise time steps.
- Live voltage and current plots that show output waveforms in real time.
- Ready-made engineering example circuits covering everything from basic lessons to more advanced systems.
- Automatic diagnostics that detect floating nets, dangling wires, and unpowered circuits.
- Arabic-first interface with dynamic switching to English.
- Export and share schematics as images, PDF files, or netlists.
- Works 100% offline. No account, no ads, no tracking.

Cirqlite is an educational and engineering tool for circuit simulation and analysis that combines easy drawing with reliable simulation. It fits electronics and physics courses, engineers who want to test an idea quickly, and makers building Arduino and interactive projects.
