I'm Leven, a former corporate full-stack engineer, team lead, and now a solo developer of Subtlex
I love learning languages, and I was frustrated by all the language learning apps that are mainly aimed at beginners, where it's very difficult to reach any level above B1
They never let you explore vocabulary from a newly released movie like "Oppenheimer" (where you only understood about 10%, but want to improve that). They don't let you read your newly bought book in its original language and limit you to a restricted, copyright-bound catalog. They don't allow you to learn vocabulary from your favorite game, which I wanted to learn and then practice while playing "The Last of Us"
These frustrations led me to create Subtlex :)
I hope you'll enjoy my app, and I'd be happy to get any feedback, suggestions, or questions you might have
