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
• Linear current regulator
• SMD packages list
• Reactance
• PCB trace resistance
Additionally, by purchasing the PRO version of the app, you will get access to additional tools:
• SMD components marking codes
• Diodes color code (Pro Electron, JEDEC and JIS-C-7012 standards)
• Linear voltage regulator
• Resistor value to color marking converter
• Voltage rectifier
• Series or parallel electrical components' connection calculator
• Diode voltage drop
• Minimum PCB trace width
• Analog to digital conversion

But please fix an issue, where everytime I want to type something, apple keyboard pops up when I have installed another keyboard I want to use, so everytime I have to switch it before typing anything.Sure it's minor problem but annoying nonetheless.

Thank you for reporting the problem. Can you please tell me at what app section (tool) you are trying to type and what 3rd party keyboard are you using?
Nice app

for sure the best app for hobbyist electronics (like me) in the whole appstore :) good job!
Developer Response
Glad that you like it 🙂
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.
