Basic but deadly useful

I’m old school and like keeping my ear in tune. I prefer a simple tuning fork or essentially, reference pitches. As advertised with no misleading claims, this app does not analyze tones. It simply provides those tones for you to tune against. It really is the healthiest way to keep your ear trained. Plus it provides quick easy reference tones for the most used string instruments we play, with no fuss and with simple visuals of the strings and open notes. And it’s free....dang!
Update 12/2019 - Having forgotten I wrote a review, I was heading to say the same as I had. A dream to use. Ùpdate 2026: Ditto

Perfect Tuning App

It’s simple good, gives you instrument options, and is the tuner that was there for me in the beginning. It’s the OG app tuner!

Me like, you use your ears to tune and quick and easy to tune

Great App!

Excellent tuner

Does’t say how to tune

It doesn’t show you what your pitch is. It’s just a recording of a note.
