More range controls please!
This app is good, especially as it's free! To make it even better, I'd like more control over the range the exercises go through. The 'Soprano' warm ups and exercises are quite low for me. It would be great if users could select a starting note and the highest note. Ideally even passing C6. Also, the ability to use this app in the background would mean I could track accuracy in other frequency apps. One thing that would make it brilliant is that once we select 'play' it goes through the whole list of exercises one after the other. As having to press 'play' each time means I can't just practice while washing the dishes etc.
