Used to be good

I used to love this app but now hate the constant ads, "health" that limits the number of mistakes you can make and constantly needing to refresh "weak words" (Duolingo seems to think words are forgotten way faster than they actually are...) etc. also the paid app is too expensive so I will just be switching to Memrise
