iOS: With the mobile app open, hit the "Schedule" icon on the bottom pane. You’ll see a new banner on top that says “Sync to your calendar”. Tapping on that button will open a new popup that will allow you to sync your calendar. As soon as you press the “Synchronise” button the link will open and your calendar app will open with the option to subscribe and name your calendar.
Android: With the mobile app open, hit the "Schedule" icon on the bottom pane. Tap the "Sync to your Calendar" banner.

Note: If you skip or you’re simply not interested in syncing your calendar at the moment, you can always go back and do it from your “More” screen inside the app. Scroll down to the General section and hit "My Calendar Sync".
