Fantastic tuner

It’s honestly worth the few bucks. It works 100% accurate down to the hertz, also has a bunch of different tunings available. Highly recommend, easy to use.

Support needed

My favourite tuner until switching to a new device. Unable to purchase or restore pro features which leaves it almost useless now. Please fix this.

Now you can tune to 432!

I should warn you though… It will be hard to go back to 440. I love free apps, and this one would’ve gotten five stars if I didn’t have to manually touch the screen every time I wanted to tune, a different string.
