Spark for iOS and Mac has a built-in calendar allowing you to manage your events and see how busy you are. Spark supports the Google, Exchange, and iCloud calendars associated with your email accounts. For example, when you add a Gmail account, you can access your Google Calendar in Spark.
Note: If you want to add an iCloud calendar to Spark, and your Apple ID is linked to an email from Gmail, Outlook, or other providers, check this article.
If you are using several accounts in Spark, it’s up to you to select which ones you'd also like to use for calendar management. For example, you may want Spark to show you only the calendars from your work account.
Spark works only with Google, Exchange, and iCloud calendars.
If you have multiple calendars, you can choose a default one. When you create a new event in Spark, it’s added to your default calendar (but you can always change a calendar manually for a particular event).
Your calendars are available in the Calendar section on the sidebar. You can choose the day, week, or month view on the top toolbar.
To switch between days, weeks, or months, use the arrows at the top right or swipe the calendar. Click on the event to see its details.
To see the events for the selected account, click on the Calendar icon on the top toolbar and tick the calendars you need. Use Select all or Hide all to quickly show or hide all calendars belonging to one account.
To find an existing event in your calendar, click on the Search icon at the top right and type your query. Spark shows all past and future events with the chosen keyword in their names. To clear the search results, click on the cross icon at the top right.
To access calendars, tap the Calendar widget at the top right of the Inbox.
When you open the calendar, it shows the events for today. Tap an event to see its details. You can select another date at the top or switch days and weeks with a swipe.
When you rotate your iPhone, Spark shows the month view on the left.
