Is there a calendar app that supports email reminders? I use Google sync to coordinate my Google calendar with my iPhone. The iPhone calendar app does not support creating email reminders. Is there an iPhone calendar app that supports creating email reminders so that when I create an event on my iPhone I get an email reminder to my Gmail account?
There is a Google Calendar app that allows you to add email notifications: 



Go to the event, scroll down a little, tap on "Add a notification"  and then on "Custom"
