It would be great to have more calendar integrations, especially Apple and Yahoo.
That’s a great idea! Unfortunately, Apple and Yahoo calendar integrations are not currently available in Toggl.
At this time, Toggl does offer iCalendar integration, which may work with some calendar services that support the iCalendar format. You could check if your Apple or Yahoo calendar can export or work with iCalendar to see if that’s a workaround for your needs.
I’ll share your feedback about Apple and Yahoo calendar integrations with the product team so they can consider it for future updates.
