Very helpful.

This is a basic tuner although it helps a whole lot since I have good ears and it really works to tune my Viola. There are many more instruments to tune and I really love the fact it has multiple instruments to tune. I recommend this to people who have good ears to listen with and tune at the same time. 10/10 awesome app.

Great tuner app

This is a great tuner app! It does just what it says, plays tuned notes. It works perfectly for my guitar and it also has other stringed instruments. I’d recommend it to anyone that has a good ear for tuning and needs quick, tuned reference notes.

No volume unless ringer is on

Since the last update I can't get sound unless my ringer is on. Why was this change made? It's annoying.

Response to update:
Thank you. It's perfect now. I use this app on a daily basis.
