Does not work well for piano or oboe
This tuner’s note indicator bounces too much to be useful for the piano and does not work at all for the oboe (e.g., displays an F# instead of C). Also, the tuner would open on my iPod, but would not install on my old iPhone 4. I tried the built-in mic and an external mic as well as different rooms. The tuner response was poor or wrong for all these situations.
