About this app
VoltSim is a powerful, easy-to-use electronics circuit simulator for Android: design analog, digital, and mixed-signal circuits, watch current and voltage flow in real-time, and debug with built-in oscilloscope & multimeter.
🎛️ Build & Simulate
• Unlimited workspace: drag & drop resistors, capacitors, inductors, MOSFETs, transistors, op-amps, logic gates, flip-flops, and more
• Real-time simulation: view voltage and current animations as your circuit operates
• Digital logic support: AND, OR, NAND, NOR, XOR, NOT, flip-flops, counters – perfect for electronics hobbyists & students
📊 Test & Tune
• Multichannel oscilloscope: probe multiple nodes, adjust scaling, view waveforms live
• Multimeter: measure voltage, current, resistance in-circuit
• Export circuits, save workspaces, share designs
🎓 Learn & Explore
• Example circuits included: RC filters, transistor amplifiers, 555 timer, ADCs, motors
• Ideal for electronics students, hobbyists, engineers wanting hands-on simulation
🔧 Why VoltSim?
• Intuitive UI built for beginners and experts alike
• Supports both analog & digital logic — a rare combo in mobile simulators
• Regular updates, new features (export/import, custom ICs, accounts)
What’s new
• Redesigned component toolbar, no more scrolling
• Script Chip: 1–16 inputs/outputs and editable parameters
• New ICs: 74189 64-bit RAM, 4008 4-bit adder, 4077 XNOR
• Manage custom ICs in Settings; find them in component search
• Community: search, circuit details and language filter
• Signal sources up to 50 MHz
• Steadier RMS meter readings
• Wire-loop and chip-packaging errors highlight the cause
• Fixes for 74xx/40xx chips, wire routing, thermistor, wattmeter, sign-up and stability
