Resistor ValCal is a handy app to calculate Resistor values. This app calculates value for both Through Hole and SMD resistors. In Through Hole 4 band and 5 band resistors and in SMD 3 digit and 4 digit resistors are supported. This app is based on international standard of Resistor Colour code and Integer code for calculating Through Hole and SMD type resistors. With the help of simple yet powerful picker view design, you can get the value for required resistor in no time.
