Doesnt work anymore.

I see it hasnt been updated since 2011. It doesnt work anymore on my iPhone 6S. I deleted it and reinstalled it but it is frozen. The red light lights up for a second then flips to the far right and the needle stays there. The A 440 tone will ring but it wont pickup any sounds to identify the pitch. Looks like the developer took the money and ran.
