It looks cool, here's some feedback on the homepage:

- it's really complex. It reads like a tech product instead of an accessible app.

- i wish i could demo it with other languages on the homepage. Greek is, well, greek. I understand some Spanish and French so if i could use those as examples I could immediately "get" the effectiveness of the app by basing it on the knowledge I already have. I would recommend showcasing the most popular language.

- should show the supported languages as icons with text above the fold.

I'm always excited to learn about new language apps as duolingo is a bit basic!
