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!

hi. why am I getting a G3 at 233.08Hz? That should be G4 shouldn't it. On piano it's Bb3 but the Alto it's G4. Also the scale running up to G on the alto sax seem to be tagged 3rd octave but the frequencies say 4th octave. Could you please clarify? Love the app btw. Thank you for the response. Please let me know when you release the result of your latest work.
The new version (2.3.0) is now available.
This version allows for negative transposition to resolve the inconvenience you pointed out.
Thank you very much.
