C'est très bon! Mais...

Below was my review, but now when I am using the app, tuner or metronome, the video thing shows up on my iPhone in iOS 9, and sometimes plays a long note and sometimes doesn't play anything, but it is really annoying because it interrupts my practice. It will also crash every 10 seconds (and I mean every 10 seconds). Could you please fix this? With it fixed, my review below is totally correct. And is anyone else having this problem?

I love the app. It has both a tuner and a metronome, so I only have to have one app. It's very accurate, and I tried out a lot of apps before this one. I like this one the best. It works for all instruments, even though when you go to tune there is a guitar symbol. I highly recommend it.

By the way, my nickname says "the viola > all the others." I clearly play viola. 😂

So good

I love this app so much it really helped me when I need to do a playing test for the cornet and I had to get to a speed. My only problem is that I don’t know how to check the speed that I am playing at. Because it shows you what your goal is at like 90 or 132 but if you want to check the speed that your at to see if your at the speed you want to be you can’t, or I can’t find it. So the app is really good but it only has the one problem.

Great for tuning my cello!!!!!

I use this app to tune my cello and my teacher always complements me for being perfectly in tune. I only use the tuner part of the app but it other cool features as well. I don’t know how it works for other instruments but I highly recommend it for other cellists.
