1. Directly adding an octave works as expected, though.A good simple useful tuner.
2. Needs a few little tweaks... Keep the tone playing when the screen turns off and remember the pitch we set it at.. for example i used 329.6 it's E.
3. Easy peasy.Very handy for checking against instruments that have been tuned electronically.Nice clean tones.
4. A simple reference pitch I calibrate for different ensembles.
5. Works in pitch and scientific notation.Lightening fast to download.
6. It's not a big deal but it would be nice if the app remembered it.Does what it says on the can - without commercials.
7. But please provide the feature to play sound in the background.Exactly what i need.
8. I also use it as a drone for practice.Does just exactly what you expect from a tuner.
9. Clear case of 5/5, well done!I liked the sound and the control options.
10. Love it!! I wonder what other apps this person offers...Just what I was looking for.
11. A sampled tuning form would be a welcome addition in a future release.
