I use… Anki 
… which surely sounds like nothing new… as many people with a more visually oriented style of learning will say 
BUT using this particular system, where I rip material from my shows and get all that sentence lines with the audio and snapshots of the actual show, it’s tons of fun!!!
I get to practice vocab, reading, listening and shadowing recycling the same content… how is that for a sale??!
Well, jokes aside, it’s a great system, self made and adjusted to whatever you’re into. It’s work, but very well worth it
