Keeps crashing!

I loved this app...but after the last update about half of my classes crash and I cant get past the second door (which is useless anyway). It just goes back to my home screen. Restarting the ipad doesnt help! Its really frustrating as a prep coverage teacher who has to take attendance for 11 different classes each week to have this app crash on me. Back to pen and paper until you guys fix it...hope you do soon!
