Great app, when it worked..

I can use the main screen to tune my ukelele, but now when I try to switch to tone the app crashes every time... If they fix that minor bug, this app would be perfect. It helps tune a wide variety of string instruments and is easy to use and understand. But they should really fix this bug.
