Ios reminders sync.
Display or sync reminders of iOS devices like Fantastical does. it will save using Calendar and Reminders separately, and also boost the market of one calendar.
Draw backs-
Also a very few updates has been available. would be nice if it has updates every 8 to 10 months so that it is current to the current needs.
the syncing time from my different calendars into one calendar is approximately 10-15 seconds.
