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 10
