I love the concept, but it has serious issues.

I was looking for something to use to help me improve my intonation while practicing on my bass, and I came across this. Unfortunately, it is very quirky, making it slow to show a definite pitch, and I noticed that while I was playing my upright bass, it was unable to determine D and D# -- specifically, D3 and D#3. I did not take the time to check for any other problems because I have already deemed it useless to my purposes until the issues specified above are fixed.
