I've been using the app Swipes together with Evernote on my iPhone and iPad for a while now, and I must say it's a pretty good app for what it does. It's a simple task management / todo app that syncs Evernote notes that has checkmarks (like a todo list). But I wish it synced Evernote reminders too though. See this vlog with my thoughts on Swipes together with Evernote.
