One of the best apps for anyone interested in electronics. More than 100 thousands users use this app in their work or study. This app has the following calculators and references:
• Datasheet search
• Resistor color and digit marking (4, 5 and 6 band color code; 2 symbols, 3/4 digit and EIA-96 code SMD resistors code)
• Electronic schematic symbols (IEC 60617, IEEE 315 and GOST standards)
• Pinouts Guide (DVI, USB, Display Port, VGA, HDMI, Thunderbolt, Apple, RS-232/422/485, ATX, RCA, MIDI, XLR, Audio Jack, Arduino, Orange Pi, STM32, ESP32, and Raspberry Pi)
• Ohm's law calculator
• AWG converter (wire diameter, cross-section area, resistance and maximum current)
• Resistor for LED
• Voltage divider
• Capacitor code
• Capacitor markings
• Capacitor ESR tables
• Frequency response curve calculation of passive filters (RC, RL, RLC, LC)
• Inductor color code

Thank you for the review. I'm glad that the app suits your needs.
In this update:
- Section switch at main menu. It allows to quickly switch between list of all, favorite and recently used calculators.
- [PRO] Ability to add your own SMD components marking codes.
- Updated Reactance Calculator. It is now possible to calculate not only reactance but also capacitance or inductance and frequency.
- [iOS 17+] ESR table shows lower and upper bounds of expected capacitance.
Big thank you to everybody who subscribed or purchased the app's PRO version. Your support helps to make this app even better. If you like this app, please rate it and leave a review.
