About this app

ElektroKit is the user-friendly electronics toolkit for makers, apprentices, students, and electronics professionals – completely offline, no account required, and no unnecessary features.

What makes it special: Each calculator displays the formula used along with your input values ​​– so you don't just calculate, you understand the results.


ElektroKit is the clear and concise electronics toolkit for makers, apprentices, students, and electronics professionals – completely offline, no account needed, and no unnecessary extras.

The unique feature: Each calculator displays the formula used along with your input values ​​– so you don't just perform the calculations, you also understand the reasoning behind them.






25 Calculations in 5 Groups:

⚡ Fundamentals: Ohm's Law & Power · Series/Parallel Resistors · Series/Parallel Capacitors · Resistor Network (Mixed Series & Parallel) · Voltage Dividers · E-Series Standard Values ​​(E12/E24/E96)

🎨 Component Codes: Color Code → Value (4/5/6 rings) · Value → Color Code with Graphic Rings · SMD Code (3/4 Digits, R Notation, EIA-96) · Capacitor Code (104 & Co.)

💡 LEDs & Power Supply: LED Series Resistor with E24 Suggestion · LM317 Regulator · Battery Life · Battery Packs (Series/Parallel) · Energy & Power Costs

⏱ Timing & Signals: NE555 (Astable/Monostable) · RC Network & Cutoff Frequency · LC Resonance · Reactance & Impedance PWM Average Voltage

📡 Wiring & RF: AWG ↔ mm² with amplitude guidelines · Voltage drop · Frequency ↔ Wavelength · dBm ↔ mW · Op-amp gain

📚 Reference: SI prefixes, LED forward voltages, complete E-series, circuit symbols.

✔ Live calculation with SI prefixes (kΩ, mA, µF, nF, MHz…)

✔ Favorites & recently used calculators
✔ Modern material design, light & dark modes
✔ German and English

✔ 100% offline – no registration, no data collection by the app

✔ Optional ad-free subscription (monthly/annually)

Note: All results are guidelines only and do not replace standard-compliant design (VDE/ÖVE).
