I changed the layout of the top screen.
Since it was changed to the new SDK, it can not connect with the previous application.
Since it was changed to the new SDK, it becomes installable on Android 4.2 or higher (Previously it was 4.0.3 or higher)
I deleted the microphone function (I will reconsider if there are many requests)
