Dont forget 2 star reviews before you buy.

The app itself is great but it will take alot of time to get use to and explore its functions, therefore, I recommend getting this app during break. Once you got the hang of it, this app will definitely come in handy if you have alot of homework and projects.
However (not sure if this happens to everyone ), Schoolhouse has some weird crashes. Such as when I enter the number of % in the weighted grading bar, for example, homework counts as 15% of my grade, I enter 15%, but when I enter the number and press ok, it crashed. It told me it sent a report to Apple but I highly doubt they will fix it. For that reason I currently do not trust this app and its functions, but if nothing happens do you, then you should be grateful and enjoy.
