This is cool. I use Voice Memos regularly to jot down ideas and it has its limitations, so work in this space is really welcome!

I don't have anything to contribute on the marketing front, so all I can say add is just keep it up! I really enjoy seeing useful cross-sections of music and software.

edit: Just downloaded it and gave it a try. Even on my iPhone 8 it's nice and snappy. Love the markers and the ability to set them _while_ recording. Great work! If I ever get around to upgrading my phone I'll definitely consider the stereo HD!
