This app is not only incredibly beautiful, it also works remarkably well! This is a masterful piece of development and I would love to see it kept up to date! I highly recommend this app!

Beats all I've tried


Why? Because of the way the colors change to reflect pitch accuracy! This means if I play a piece on my violin and the green flashes to red, I need serious pitch adjustment. Talk about instant feedback!

This is vital for any violinist, beginning or advanced. (I consider myself to be intermediate, fyi.)

If Jony Ive designed a tuner for Middle-earth...


…this is what it might look like and how it might function (to the delight of elven minstrels).

The interface is as clear and obvious as it is ornate. This app’s balance of design and usability draws me to use it more than any other tuner.

Teüna is a refreshing departure from the more common missile command-esque tuning apps that populate this app category.
