Description

Decode resistor color bands in seconds. Built for electronics students, engineers, technicians, and Arduino, ESP32, Raspberry Pi makers who need a fast, accurate ohm value from any resistor.

KEY FEATURES
• 4-band, 5-band, and 6-band resistor support
• Instant resistance value in Ω, kΩ, MΩ, GΩ
• Tolerance percentage (±0.05% to ±20%)
• Temperature coefficient (ppm/°C) for 6-band resistors
• Reverse calculator: enter a resistance, get the color bands
• Complete IEC 60062 color chart reference
• Realistic resistor visualization
• Material 3 interface with light and dark themes
• Works fully offline — no internet, no account, no signup
• Calculations never block your workflow

HOW TO USE
1. Pick the number of bands (4, 5, or 6)
2. Tap each band and choose its color
3. The ohm value, tolerance and temperature coefficient appear instantly
4. Use the reverse calculator when you know the value and need the bands
5. Open the color guide anytime for the standard color code reference

WHO IT IS FOR
• Electronics and electrical engineering students
• Technicians and field engineers
• Arduino, Raspberry Pi, ESP32 and microcontroller hobbyists
• DIY electronics builders, makers, ham radio operators
• Anyone repairing circuit boards, amplifiers, power supplies

WHY THIS APP
Reading resistor color bands by eye is error-prone, especially for 5-band and 6-band parts with tight tolerance. This calculator removes the guesswork. Pick colors, read the value, get back to your project. The interface stays out of your way: no menus to dig through, no popups breaking your flow.

The color chart follows the international IEC 60062 standard, so the results match what you see on any resistor from any manufacturer. The reverse calculator is handy when you need a specific resistance for a circuit and want to know which bands to look for at the parts bin.

LIGHT AND DARK THEMES
Switch between light and dark mode, or follow your system theme. The resistor preview adapts automatically so color bands stay accurate in both modes.

MULTILINGUAL
Use the app in your preferred language. Change it anytime from the settings screen.

PRIVACY
No personal data is collected. All calculations happen on your device. Ad consent is fully manageable from the settings screen for users in the EU and UK.

Download and make resistor identification effortless.
