Sure! You can view Flo Calendars in any CalDAV-compliant Calendar app. Here is the info that you will need to connect in Apple iCal and this should also work for other Calendar clients.
Config Flo account to ical 8:
- Account type: Advanced
- user name: Your Flo email address
- password: ********
- server address: http://flomail.net
- server path: /calendarserver.php/principals/email (email is your flo email address)
- port: 8087 (or 8089 for new SabreDAV version)
- uncheck "use ssl"
- uncheck "use kerberos v5 for authentication"
