Wish it would coordinate with Calendars

But it doesn’t. It’s just a todo list. BusyCal, by these same folks is a MARVEL. It’s a desktop app ONLY and scoops up all info from reminders and ical events. AND it coordinates with ical and reminders. But for IOS, you need something better than a todo list. You need coordinated reminders and events. Pocket Informant will give you that. It will scoop up everything and give it to you to use and modify on your devices (iOS 7 I think only at this point). So I use BusyCal on my desktop as my default calendar and I use Pocket informant in my pocket.
