Coursepad is an independent app. If something isn't working or you have a request, email [email protected] and you'll get a real reply.
Open Planner, tap a semester, then "Rotating schedule." Choose the cycle length (2 for A/B), label the days, and pick a start date. When you add a class, choose "Rotating" and select its day.
Sync is part of Coursepad Pro. In Planner → Settings (gear) → Sync, start your free trial and sign in; your schedule, assignments, and grades then stay in step across your iPhone, iPad, and Mac. Without Pro, everything still works fully on a single device.
Add weighted categories to a course (they total 100%), tag assignments to a category, and enter scores. Coursepad shows the live course grade, semester GPA, and cumulative GPA across past terms.
Settings → "Import .ics as assignments." Export your old schedule to a calendar (.ics) file and import it into a course.
