Resistor Tools Pro app for iPhone and iPad

This app is a collection of resistor calculators. It is suitable for hobbyist or electronic engineer.

* Calculate resistance of 2 resistors in series or parallel
* Find out combinations of 2 resistors in series/parallel making a desired resistance
* Calculate ratio of R1/R2 and voltage divider
* Find out resistor values of making voltage divider ratio
* Find out resistor values of making inverting amplifier gain
* Save combination values in CSV file
* Share document via AirDrop
* Upload CSV file to iCloud Drive (For iOS8 or later)
