InductorCalc

With this app, you can calculate the inductance, Q-value, resistance and needed wire length for your diy inductor/coil. 

For inductance and wire length, put the number of turns, length and diameter of your coil. For Q-value, put also the frequency used by your coil. For resistance, put also the resistance of the wire you are using in ohms per meter.

Tap the calculate button and the app will calculate the values for you!
