Great Concept, but voice too quiet – Yoga with Tania Lite Review

I have an iPhone 4, and with it not muted, and volume at 100%, I am having trouble hearing the instruction. She has a pleasant voice, but too soft-spoken. I would buy it, if this was fixed, since the whole concept is just what I am looking for in a Yoga app.
