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.

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!

Good visualization

This is the tuner app I decided to purchase. The free version is great too. Lots of decent free tuners out there but this one seems the most natural for precise tuning. Update after much more use: it’s still the tuner app I prefer.
