Looking for a marketing / business cofounder for almost finished SaaS web app for guitar

Hey all,

The app is currently deployed here - https://guitarflow-95c71.web.app/
It's a guitar tab player that incorporates voice recognition.

Me and many guitarists I know had this problem where you constantly have to let go of the guitar and grab the mouse to adjust the song or hear a certain part again etc. It was very disrupting and tedious so that's what sparked the idea.

Currently most of the things are done easily with short voice commands and the app is useful to me and couple of my friends, it's also 100% free atm.

The app is 95% done and the reason I'm only now looking for a cofounder is because I was a noob when it came to marketing until recently and didn't realize how much work it actually takes.

Thanks and i'd appreciate any feedback at all regarding the app!
