Saturn

Power Planner

Assignments and exams

Homework and exams are added with due dates, and each task or event can carry a checklist of sub-items on iOS, Android and Windows.

Class schedule

Classes are entered with times and room locations and shown as a weekly schedule. Alternating Week A and Week B schedules are supported.

Grades and GPA

Grades are tracked per class with weighted categories, GPA is calculated across semesters, and a What If? mode shows how a future score would change a grade.

Automatic reminders

A day-before reminder lists what is due tomorrow and a day-of reminder arrives an hour before an item is due. Both are on by default and can be turned off.

Online sync

A free online account keeps the planner in step across desktop, phone, tablet and browser. A local account that keeps all data on the device is also offered.

Widgets and Google Calendar

Home screen widgets on Android and iOS show upcoming assignments and classes, and classes and homework can be viewed in Google Calendar.

Saturn

School schedule formats

Handles rotating periods, block schedules, A/B days, lunch waves, advisory and flex blocks. The listing says Saturn is in over 20,000 US high schools and can be carried on to college.

Compare calendars with friends

Shows when friends and family are free without needing their email address, so overlapping free time can be turned into a plan. Friends appear alongside your own calendar on the home tab.

Shared and group calendars

A shared calendar can be made for a trip, a household, a club or a team and joined through a link. Members get change and reminder notifications as events are updated.

Typed or spoken event entry

Typing or saying a phrase such as "Dinner with Dylan on Tuesday at 7" puts the event on the calendar. Events, to-dos and reminders can all be added by text or voice.

Google Calendar and Snapchat

Google Calendar can be connected so its events appear in Saturn. Connecting Snapchat brings in friends, birthdays and Bitmojis.

Apple Watch app and widgets

The Apple Watch app shows a countdown to the end of the current class or event, a schedule view of the day and watch face widgets, synced from the iPhone app.
