Good tuner!

Out of all the other tuner apps I’ve tried and used this is the most accurate! Many of the other tuners doesn’t put my guitar in to or near perfect tune like this app.

This app is helpful.

This app is good if you don’t have an “actual” tuner I suggested this app to my friends and they liked it!
