My ipod touch calender is not syncing with icloud
I have a calendar app called Week Cal on my Touch 4g. It is not syncing with my iCloud on my PC. On the iCloud settings on my Touch, my Calendars is switched to "ON". I plug in my Touch to my PC. My Contacts works fine. What else do I need to do?
iPod touch (4th generation), iOS 6.1.2
