How to Activate All Tools of the EvaF Mobile App

EvaF 2.3.5 provides trans feminine speakers with hours of video instruction and more than 160 specific exercises over twenty individual lessons. The training tools include an especially coded pitch tuner (when the green circle alights, you know your pitch is on target), a pitch tracker (designed to fine-tune your pitch control in vocal slides and glides), a sound meter, a metronome and a voice recorder.  There are currently five available tools. The resonance analyzer is in development and is targeted to be released in 2020.


Each Eva lesson is purchased individually ($4.99 each lesson, iOS and $79.99, Android, for the whole program). The sample lesson is free. 


The 20 lessons of the Voice Feminization Fundamentals course provide everything you need to get started with your voice. It is a structured program and to fully get everything you need for you voice, you’ll work with all twenty lessons. Some of the tools on the “Tools” page only activate when you’ve purchased specific lessons.
