Not yet, Google Calendar is the only calendar integration available right now.
When you connect Google Calendar, your events are imported into Existence as Time Blocks, giving you a structured starting point for your day without having to build everything from scratch.
If you use Outlook, Apple Calendar, or another platform, you can still use Existence you'll just create your Time Blocks directly inside the platform. Many users find that building blocks manually actually deepens their relationship with how they're designing and accounting for their time.
More integrations are on the way, this is just the beginning. As Existence grows, so does the number of ways you can get your time into the system.
