The app itself is a bit of a different take on the problem space than many of the other well-known offerings in the market. iOS only for now, SwiftUI, and built around enabling "Compelling & Comprehensible Input"-based language acquisition using video, audio, and text you've supplied yourself.
Interestingly - when I started the project I reckoned it would be about 2 years to shipping something useful, which would mean about Q3/Q4 2020. I'm starting to think that estimate was, shockingly, about right.
Cheers to everyone and their projects!
