I absolutely love this app, but unfortunately I can't continue past the free trial because it's not in the budget. Hopefully I can catch it on a good sale one day. The few sakes I've seen heavily push for the yearly subscription. Most of us are broke students who can't afford annually. Please strongly consider making sales focus on the monthly rates.

Missing a lot of features, but more importantly, it doesn't always work. Lately the flashcards haven't been loading so now I'm only using it for the occasion video. Makes it impossible to do cards on the go because I'm not going to pull out my laptop on a commute. Messaged support about this bug and they are great at acknowledging your comments but they don't seem to act very fast because it's been 2 weeks and this bug is still present! Honestly, flashcards are the main feature for me too :(
