Calendar Apps for the iPhone

I am having issues with the calendar app for the iPhone. Still after 2 - 3 years of issues, it's unable to sync subscribed calendars properly.

I just tried Calvetica Classic and it wasn't up to the standards.

Can you guys suggest me some great calendar apps for the iPhone? Also, if you can guys can also check if they properly sync colors for subscribed calendars with the Calendar app on the desktop?

Thanks!
