MLeeJackson ,

Good app

It’s a cool app I believe with a little more effort and more presents and a prettier interface this app could really take the music world by storm whoever developed this app , it’s simply amazing keep at it .

earlytimesguy ,

keys stick

unusable so far.

Pianoplaya13 ,


The notes won't stay selected so you have to hit them lol together to get the chord name. Needs improvement.

Developer Response ,

There is a choice "keyboard type" by setting (button on upper right).
Please try "monophonic" mode.
Perhaps it will meet the requirements.
