I never used the app and passed the bar this past February using them. I'll tell you what I did which worked so well. As an initial matter, I am not a great test taker nor did I learn the 1L material. I went to a decent school though.
I officially had the barbri course but only finished about 50% , as the program was wasting lots of my time and was not sinking in. So, i bought the critical pass mbe flashcards and used them only coffee breaks, walks, errands and during my other random down times. I did each pile slowly and carefully about a total of 10x times each.
I would advise you to read them enough to feel like you are going to sleep with the elements in your dreams. Dont forget - the bar tests your memory so flashcards are great for imprinting the items into your head.
