What's the Frequency?

What's the Frequency is a simple ear training app to help improve frequency recognition. I designed and developed this app as a goal to help motivate various learning exercises in iOS app development, particularly how to animate custom views to create the wavy lines at the bottom of the screen, which change to reflect the current frequency.

The app is available for free on the iOS App Store https://itunes.apple.com/us/app/whats-the-frequency/id807110901?mt=8
