I was a linguist in a former life, so these apps always intrigue me. I've made a few attempts myself over the years. Yours looks slick and would've been an interesting one to check out if I were learning a language.

I signed-in and took a look around getting a few "Error rendering home" errors occasionally, fyi.

I was a little surprised at the CC#/subscribe page, since the prices didn't seem to be matching up with the marketing pricing page.

You might want to consider having like a sandbox account with some sample materials so people can feel the power of the app rather than depending on someone subscribing based on the video only.

Cool idea!

Thanks for the kind words! Sorry about the errors, I’ll get these sorted out.

The CC page will be updated next week sometime - for now I’m letting people register at the old prices (50%) while I’m plugging all the holes.

And the sandbox is coming! It’ll be on the marketing page, just under the video. It’ll probably take a month to get around to though. That, plus a trial week ($3.99) should hopefully give the user a taste
