Practice saver!

I dont know anything about music, but when my son said his violin was so out of tune he couldnt practice, and it was a few days before hed see his instructor, I got this app.
Tuned his violin in 5 minutes, and he was happily practicing again.
Larer, His instructor, using professional tools, said the violin was well tuned.
So Im very happy with this app.
