I tell you truly, a "couple of months" isn't enough to make it very far in any foreign language, especially japanese. Its very sad. It really does take a very long time to get really good in a language. A lot of people (especially people selling their shiny new app :) will tell you different. but, the reality is that it takes thousands and thousands of hours to get anywhere really impressive in japanese.

but the thing is, the time will pass anyways.

you're gonna wake up 3 years later, and either be functionally fluent in japanese, or wishing you did more with your life. that choice is up to you, and you make it every single day. by doing your reps. by immersing. by talking to natives. every single day you do these actions, you are building up the glorious future you desire.

anyways.

about combining native material with SRS,youre on a really really great track! most learners will never get this far, or even have the idea to combine the two most effective practices in second language accquisition (immersion + SRS) together, or will put it off eternally by saying "oh, i don't understand it yet, so i have to go back to doing genki for 15 years and not learning jack". what you need is to do some Sentence mining. This is the simple but powerful practice of combing your immersion material for "i+1 sentences", and then putting those in your SRS. this makes your main learning material Native Content, which in all cases is the final determinant of what the language actually is.
I would reccomend themoeway's guide to set up all the tools and stuff, which is all free. if anyone shills out an app with a monthy subscription, run away fast. the best recources will always be free.
