ATTENTION: To set up timr in your calendar application, you need to generate a private URL. You can see how to do this here.
1.Open up the calendar app installed on your Mac. In the menu bar click “File - New Calendar Subscription…”
2. In your timr Account go to Administration/Settings and click on “Generate private calendar link”. Enter this URL in the dialogue and confirm with “Subscribe”.
3. Now enter your timr login and password and click OK.
4. Now you can adjust the shown calendar name and set a color for the calendar.
Furthermore you can choose where to save the calendar.
If you choose iCloud, it automatically appears on your connected iOS devices as well. If you can't choose iCloud you have probably reached the maximum amount of iCloud calendars.
Finally you can choose the refresh interval. Click OK and you have successfully added the calendar.
