Ratings and reviews

I've used some version of this app on my desktop, laptops, tablet, and phone. The pay version is worth the price because of the features. I like this because it's simpler to choose the note you want. I am a bassist. I also play guitar, violin, and banjo. This will work with all of them! You should remember that it's not plugged in so you need a quiet place. I use an electronic tuner on stage so I can plug in. I don't think this has option to plug in. Hint!

I am a practioner of sound healing. I use this to see what frequency or key my Tibetan Bowls are in, as well as checking the accuracy of certain sound healing tracks (for example, a YouTube track that claims to be 432hz can be played and this app will verify or falsify the video's Hz claim). Very useful and very accurate, thank you!

It was A-Tuner however great this app is its not what I was looking for as I'm looking for a tuner that will tune down half step , Full Step and also with option of tuning a 12 string...
