Hey folks!
I built Echo Prof (echoprof.com) for mobile (iOS/Android). It's an app for studying that you can talk with. In a nutshell, it uses spaced repetition, multi-lingual speech synthesis, and multi-lingual speech recognition to reduce the effort you need to study languages.
I think lots of people would like the app if they knew it existed (evidence is that Anki community is large, Duolingo community is large).
I've been coding it for a couple years now, and I think I'm at a point where I can't really take the app much further on my own. Does anyone have any advice for finding a teammate or part-owner? It would be really helpful if I could find someone who could do a bit of marketing and maybe some design work.
