Design faster, check formulas instantly, and get confident answers—whether you’re wiring a prototype, laying out a PCB, or verifying lab results. This all-in-one toolkit brings together the most-used electronics calculators so you don’t have to jump between apps or spreadsheets. Core Circuits & Passives • Ohm’s Law (V, I, R, P) • Resistor color code (through-hole & SMD) • Series/parallel & voltage divider • Capacitance & capacitor impedance (RC) • Inductance/reactance/admittance; coil/loop inductance • Battery life estimation • RMS/peak/peak-to-peak voltage • Decibel (dB) converters for power/voltage levels Analog & RF Essentials • Op-amp gain/voltage and inverting resistor calculators • Impedance matching: π-match and T-match • RF power: ratio/units conversion, PAE, N-way power divider • dB/dBm helpers for quick link-budget math These are the same families of tools engineers rely on for day-to-day analog and RF work. PCB & Signal Integrity (EDA) • Microstrip/stripline impedance (single-ended & differential) • Trace width and max current • Crosstalk (edge/broadside), wire/microstrip inductance These capabilities mirror what dedicated PCB toolkits and online impedance calculators provide—now in one place on your phone. Electromechanical & Power • Lenz’s & Faraday’s laws (induced EMF) • Torque conversion and stepper motor helpers • Flyback SMPS building blocks • Heat sink basics & power density • Peak/peak-to-peak/RMS and power conversions These bridge the gap between bench calculations and real hardware choices. Physics & Foundations • Lorentz force, electrical energy, RC time constant, LC tank resonance—handy checks for labs and exams alike. Why this app? • Comprehensive: from Ohm’s Law and resistor codes to PCB impedance and RF power—covering the everyday set engineers actually use. • Built for speed: clean inputs, clear results, and units you expect. • For everyone: students learning the basics, makers iterating quickly, and professionals verifying designs. Perfect for: electronics labs, field service, ham/RF projects, PCB layout checks, audio/dB work, and rapid “sanity-check” calculations during reviews.

Verdict

The call

The clearest difference is in-app purchases: ICS at none against Electrical Engineering Toolkit's 3. ICS also leads on iOS requirement (13.0 vs 16.2). Electrical Engineering Toolkit's advantage is device support. On price there is nothing between them.
