Saturn vs School Assistant

Saturn

• High school students with rotating, block or A/B day schedules
• Friends who want to see when each other are free without swapping emails
• Clubs and teams that need a shared calendar members join by link

School Assistant

• Students on Apple devices who want a planner at no cost
• Class schedules that alternate between A and B weeks
• Checking assignments and the next class from an Apple Watch

Saturn

• Mobile apps only: iPhone, iPad, Apple Watch and Android. No web or desktop version is listed.
• The website still presents Saturn as the calendar built for high school, and the terms limit each school community to students of that school.
• Google Calendar is the only outside calendar the store listings name as a connection.
• The terms of use require users to be at least 13 years old.

School Assistant

• Apple devices only: iPhone, iPad, Mac, Apple Watch and Apple Vision Pro. No Android, Windows or web version is listed.
• There is no calendar view inside the app. The developer chose to show schoolwork in Apple Calendar through Sync to Calendar.
• The Siri AI integration is limited to supported devices, and Smart Create depends on Apple Intelligence.
• Sun Apps is run by a single developer, according to its About page.

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.

School Assistant

Schoolwork

Assignments and tests carry a class, due date, links, notes, subtasks and reminders, can be sorted several ways, and move to an archive when completed.

Schedule

Classes are listed for each day with teacher and room, or a link for online classes. The schedule can switch automatically between two weeks or manually between up to ten.

Classes

Each class has its own page for the teacher's name and email, a class code, links and notes, with an icon and a color that carry over to schoolwork.

Apple Watch app and widgets

The Watch app shows schoolwork, the schedule for any day, and the current and next class with time left. Home Screen widgets show assignment counts and the current and next class.

Siri AI, Shortcuts and Smart Create

Version 5 lets Siri AI on supported devices answer questions about schoolwork and create it, adds Shortcuts actions, and turns pasted text into entries with Apple Intelligence.

iCloud sync and Sync to Calendar

Data syncs automatically across devices over iCloud, and schoolwork can be shown in Apple Calendar through the Sync to Calendar feature.
