Best Tuner But..

The free version is able to do landscape mode but the PRO version can’t on the iPad. I love this tuner but I’m stuck using the Free version because it is stuck. In portrait mode. Also since the latest update the pro tuner is stuttering badly. The Free version does everything I want in a tuner but I just want the pro version to be exactly the same without ads. Please fix this issue.

Best tuner I’ve seen for OS!

I’ve played acoustic guitar for more than 40 years. In the past, I’ve always found it necessary to use a 440 tuning fork as even the most expensive electronic tuners failed to work well consistently. This app “just works”. I finally feel confident that I may leave the turning fork behind.

More useful than expected.

I play the flute. This app is Great for practicing long tones. It makes improvising with other musicians or recorded music easy because it reads out the notes as they are are being Played. Now I can easily tell what key the music is in and play along. Very cool!
