How can I save the sessions in my calendar?

In Worksup, you can click on the heart next to your favorite sessions to keep track of this list (via the heart in the top right corner). You can also export the sessions in your calendar. The export is totally dependent on yout device's settings. Some of the devices are just downloading the .ics file and you need to manually upload it to preferred calendar app (e.g. Google Calendar); some of them are directing the .ics file already to the calendar app that is selected as your "by default" one.
