Learning Darija

Assalamu alakyum

Im half moroccan not born in Morocco and unfortunately I never learned darija properly. Yes shameful I know. I understand more than I can read/talk and know how to read arabic but I dont understand it well either.

Im currently learning and I want to know what is the best app or website to translate darija and one for arabic? I tried some sites like google translate for arabic but even I notice its not very good.

Thank you!
