I played with your apps just to test suitability for my need,  and it is quite good.
But please be aware that the app can sometimes crash during audio recording, and when it happens ,  it quits to the main page from the note I was working on ,  while the recording keeps continuing in the background. There is no way to stop it except to forcefully terminate the app from memory.

I'm not sure if it is a total crash,  because the app seems to recover itself by quitting to the main page without error message, while the audio recording keeps continuing in the background.
