In this podcast, Abby gives us a walk-through and demonstration of SingTrue: Learn to sing in tune, pitch perfect, an iOS app which claims that it can teach anybody to sing in perfect tune. Even if you think you're tone deaf.

SingTrue features over 30 interactive exercises* that help you learn to sing easily, confidently and in perfect tune. By using the iPhone microphone and sophisticated signal processing, the app analyses your singing and provides personal feedback on how you can improve.

If you are already a musician, the app will train your voice and your ears to help you become more confident, more creative, and more musical. In fact, the advanced exercises will help you recognise notes by ear - enabling you to play by ear, write your own music, and improvise freely on your instrument.

The exercises have been designed by experts, in consultation with some of the leading vocal teachers in the world. Building on the success of the RelativePitch ear training app (featured by Apple and used by over 300,000 musicians) and the Tone Deaf Test (4.5-star rated app used by 170,000+ people), SingTrue has been developed to help more people discover their inner voice and naturally become sensational musicians.

SingTrue is a US$0.99 download from the App Store, with additional features available as in-app purchases.
