Best guzheng tuner on AppStore!

If you have a Guzheng this app is a must have. Other tuning apps don't work nearly as good. Works great even with some background noise in room. Pay the $1:99 and never worry about an out of tune guzheng again!!!

A little hard to learn at first...

I am a total beginner and I was able to tune all 21 strings after I learned how the gauge worked. I learned to tune the Guzheng from a source that used numbers and letters to identify the string and key and a green color to identify that the string was tuned correctly but this app uses a gauge, so it was a bit confusing at first. I had to use another app to understand that when the needle is at 0 it is tuned to the correct key as well as setting the string number instead of using auto. Some of the apps instructions were useful. I’ll be using this app again to retune my Guzheng and I am very grateful to the people who created this app! I was able to start learning this wonderful instrument so much sooner:)
