I've found I'm better off paying extra for a shorter duration until I've validated that I'll be using my subscription in 3/6/12 months from now. E.g. recently with Duolingo I ended up only paying for it on a monthly rate for about 4 months, and that wasn't even because I'd quit learning, I'd just found a much better app.
