Cute idea for my first graders but... – Math Chicken - Number Line Review

I am writing this review as a teacher that has one classroom iPad. This problem may not pertain to personal use. I like the number balance and the addition problems but I need a way for the next student to start at level 1 not where the previous student left off. The other Chicken app (Chicken Bounce) shows different levels and I can have the kids start at one. To start my aforementioned student in the app on level 1 I had to uninstall and reinstall. I will not be doing that for every kid.
