Saturn vs Smart Timetable

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

Smart Timetable

• Students and teachers whose timetable rotates over two to four weeks
• Seeing the current and next class on a widget or a watch
• Sharing one timetable with classmates or coworkers

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.

Smart Timetable

• Multiple schedules, class and task reminders, device sync, files on tasks and Apple Calendar sync are all listed under Premium.
• The website shows no prices. The US App Store lists five in-app purchases from $0.99 to $7.99 and names a term for only one of them.
• The browser option is described as a web version of your schedule. The site does not say whether a schedule can be edited there.
• No Windows app is listed.

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.

Smart Timetable

Rotating and multi-week schedules

A timetable can repeat over 1, 2, 3 or 4 weeks or follow a rotation. Keeping several schedules at once, for school, the gym and so on, is a Premium feature.

Homework tasks with attachments

Tasks are added to any day of the schedule and can carry photos, video, audio or documents. Attaching any type of file is listed under Premium.

Class and task notifications

Regular class notifications and homework reminders. The vendor's FAQ lists class and task reminders among the Premium features.

Widgets and watch apps

Widgets show the current, next or tomorrow's lesson with a countdown to the end of class. There is an Apple Watch app and widget, and Wear OS is supported.

Schedule sharing

A schedule can be sent to friends or coworkers by code or by a link to its web version. Sending a schedule that stays in sync is a Premium feature.

Sync and Apple Calendar

Premium synchronizes schedules between devices and with Apple Calendar. The App Store listing also mentions iCloud sync and Siri Shortcuts.
