On the right side of both the week and day views you have a full month calendar, with dots below each day that symbolize the number of classes and assignments for that day. This makes it easy to see just how busy a day is at a glance.
Finally, iStudiez Pro also features grade-point-average tracking, letting you assign weights to each type of assignment. As you receive your graded homework, quizzes, and exams, you can enter in your grades and the app will track your GPA -- even over the course multiple quarters or semesters.
Differences on the iPhone
On the iPhone, the layout isn't quite as fancy and the buttons are in different locations, but the functionality is all still there.
Buttons at the bottom of the screen get you to the day and monthly calendars, and there are also buttons to track your assignments. The Planner button in the lower right lets you view classes and schedules for each semester, and you can view holidays and your instructor list.
Where you had a button for the week view on the iPad, on the iPhone, it's a little bit different. When viewing the calendar, simply turn your phone sideways to switch to the week view. Here you'll see all your classes laid out, with the color-coding I talked about above, and days of the week. You also can reverse-pinch to zoom when it's difficult to see. Unfortunately the zoom only works on one (vertical) axis, so you can zoom things to be taller, but not wider. Hopefully this is something the developers will fix in future updates.
iStudiez Pro is one of the best college scheduling apps I've seen, going the extra mile to be flexible while keeping the interface readable at a glance and easy to use. This is the type of app I wish I had in college because once you go through the initial setup, everything is laid out for the whole semester. Any changes you make only take a couple of taps, so the app stays out of your way, but keeps you on point to complete assignments and get to classes on time.
