This app will help you to measure, inductance, capacity, and resonance frequency. This is a wireless LC meter
Use this app is easy, you just need build a small circuit (easy to build) and connect to the circuit capacitor or inductance you need measure, put your smartphone near from this LC meter circuit choose what you want measure, inductance or capacitor and press play button in the app. The app will detect sound frequency from buzzer and will show value.
LC meter range:
Inductance - from 100uH to 100mH
Capacitor - from 10nF to 10uF
If you need an cheap and easy to build LC meter, this app good solution for you. Also you can improve the circuit by adding different reference value capacitors an inductance.
Components you need to build the circuit:
1 - Capacitor C1, C2, C3, C4 - 470nF
2 - Inductance 10mH
3 - Transistors Q1, Q2 - BC557
4 - Resistance R1 - 10K
5 - Resistance R2 - 100
6 - Resistance R3 - 220K
7 - Resistance R4 - 5.1K
8 - Switch (3 pines)
8 - Buzzer
