Almost all language learning apps were created by engineers or software designers. For them, teaching is an afterthought at best.

Cogdex was created by a professional teacher of English as a second language incorporating the latest understanding of how people learn languages.

"So many language teachers complain about the quality of language learning software. I wanted to do something about it and help all the people who can't take classes right now."

"Cogdex not only incorporates my professional knowledge of language learning, but my own experience learning foreign languages. I wish something like this existed when I learned Spanish."
