you're wasting your time. you're not going to be writing anything in spanish that anyone is going to critique for proper grammar, accent marks, spelling or capitalization.
Well I am going to be writing something in Spanish and I don't want to talk about anuses (anos) when I mean years (años).
I have the same experience as CNS. I can recognize and read the sentences pretty well, but I wouldn't be able to say or write some of them because I can't remember the proper verb conjugations. Actually the app never even taught the verb conjugations, it just started using them.
I do like the parts where it makes you say stuff and tells you if you are saying it right. I also like that there is a button to tell it that you can't talk right now (turns it off for an hour) but I clicked that 2 days ago and it hasn't had any speaking requirements since then.
