If I were to reply in bad faith, I'd say /jp/.
But really, go to /int/ and check /DJT/. Ask there.
Also, a tldr; as a language teacher myself:
no app will teach you a language. You need to USE the language on a daily basis to learn it, and you need a teacher who'll correct your mistakes and explain the differences between your native language and the language you're learning. If you ever start any EFL classes, don't fall for the "CLASSES WITH NATIVE SPEAKERS" scam. 99% of the native speakers who pose as language teachers have no prior teaching and linguistic education and won't be able to tell you, for example, why in Polish language there's no "an" and "the" and why in German "the" turns into "der, die das" and then transforms into "den, dem, des" etc. Native speakers will just tell you "it's the way it is" but won't be able to explain WHY.
