Worth every penny!
This is hands-down the best app Ive used for voice training. There are a ton of exercises for every skill level and the developers continue to update the app. I got a TON more lessons to download for free when they updated, and paid nothing. It was so extensive they could have easily charged for it, but they didnt. Excellent app, excellent support. Worth the money.
