About this app

OhmStudio – Your Offline Electronics Companion

OhmStudio is a clean, fast, and 100% offline app designed for students, hobbyists, and engineers who want to understand and calculate core electrical quantities — Voltage, Current, Resistance, and Power — anytime, anywhere. No internet connection required.

⚡ OHM'S LAW LAB
Solve for Voltage, Current, or Resistance instantly using real-time interactive sliders. Watch the classic V-I-R triangle update live as you adjust values, with automatic unit conversion (mV, mA, kΩ) for accurate, easy-to-read results.

🔋 POWER CALCULATOR
Calculate electrical power using all three standard formulas — P = V×I, P = I²×R, and P = V²/R — with live-updating equations that help you visualize how each variable affects power output.

📘 LEARN SECTION
Explore bite-sized, offline educational content covering:
- What is Ohm's Law?
- Understanding Voltage, Current, Resistance & Power
- Series vs Parallel Circuits
- Reading Resistor Color Codes

🕓 CALCULATION HISTORY
Save your calculations locally on your device for quick reference. Review past results anytime, and clear your history whenever you like — full control, always in your hands.

🎯 QUICK PRESETS
Jump straight into common circuit scenarios (like 5V + 100Ω or 9V + 220Ω) with one tap using ready-made presets on the Home screen.

🔒 100% PRIVATE & OFFLINE
OhmStudio works entirely on your device. There are no ads, no trackers, no analytics, and no internet permission required. Nothing you calculate ever leaves your phone.

Whether you're a student learning the basics of electronics, a hobbyist working on a circuit project, or an engineer who needs a quick, reliable reference tool, OhmStudio gives you fast, accurate calculations with a clean, modern dark-themed interface — no sign-up, no data collection, no distractions.
