Great, accurate tuner. Possibly the best on Play Store, and I have used and tried many. Will be using and testing over the next few weeks. My advice to the developer - don't fix what isn't broken. I'll be back to update. Thanks!

The only worthwhile tuner on Android. It's simple, looks good enough, and the ads are easy to block.

Although intended for instruments, this app is also great for finding your vocal key, so I'm rating it 4-stars for now. When I get familiar with it, maybe It'll change.
