   GCalSync - Sync your Google Calendars▲3

   We were running into the issue where it was extremely hard to manage and juggle multiple calendars across personal, work, and sometimes multiple clients. The problem was not so much what I can see, but rather what time others can see on my calendar as available. Hence, it made sense for us to sync calendars across accounts.
