Overall, this app is pretty good for what it tries to do. I like the option of using a point grading system, as some of my courses use that instead of a classic percent scale. However, it still has some significant flaws.
Both in app and on the store, this app claims to use iCloud sync between devices, yet this functionality does not work at all. Everything needs to be entered twice, which takes away from the convenience of such software. Additionally, the app crashes every time I submit a grade. Admittedly, its only a minor inconvenience, as the grades are still recorded, but its a flaw. My last issue is the inconsistency in calculating dates and grades. I often see an error on the assignment overview for the date, and my grades are mostly nan% for some unknown reason.
I do think this app is off to a good start though. A few tweaks, and it might even be a contender for iStudiez.
