  I'm making an open-source platform for learning Japanese2025 · kanadojo.com · ▲288

Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point.
