Simple and brilliant! Thanks :)
VERY useful. VERY easy to use.
A simple tuning fork. A 440. If you know how to tune your instrument, this should be all you need.
This app is exactly what I’ve been looking for! No ugly sustained tone; no superfluous pitch selection or—worse yet—insulting frequency measurement. Just an adjustable A4 with a well-measured decay. Love it!
Using tuner pedals for decades severely impaired my ability to tune by ear. But this great little app on my phone has brought it back up to snuff. Plus I now always have tuner in my pocket!
