Excellent and easy to use

I purchased all of these tuning apps for my string instruments. It's easy to use. I'm no super great violin player, but for a beginner in his first few years, I find this app easy and quick......especially with my wittner finetune pegs

Developer Response ,

Dear Mike, we are pleased to hear that you enjoy using our professional tuners. Each one of them was carefully designed and developed in every detail to provide the greatest efficiency and speed when tuning.

Get ready for more features in our next update! Hope you have an awesome day. Daikyouju Labs

Not what I expected.

Most tuners have a dial to show if pitch is too high or too low. This only shows the pitch # and a beep when proper pitch is attained.
Not as user friendly as some. Regret the purchase
