In their own words
Power Planner
Power Planner is a student homework planner that syncs assignments, class schedules, grades, and GPA across devices. Students can enter homework and exams with due dates and receive automatic reminders, then add class times and room locations to view a weekly schedule. The app tracks grades by class, calculates GPA across semesters, and includes a “What If?” mode for planning ahead. Classes and homework can appear in Google Calendar. It supports standard and rotating A/B week schedules, but not fully custom non-A/B class schedules; the maker also says there is no Canvas or Blackboard integration. The Free plan costs nothing and is limited to one semester, five grades per class, one repeating bulk task or event entry, and one photo attachment per item. Premium is a one-time lifetime purchase listed at $4.99 a month, with unlimited semesters and more than five grades per class. Power Planner is available on Android, iOS, Windows, Mac, and web browsers, with web marked beta. An online account is optional; local-account data stays on the device.
