Headspace is probably the easiest and best way to get started with meditation, due to its great instructions, sublime voice quality (both technically and phonetically/subjectively), and clear motivating daily progress (with reminders).

This video [1], which occurs early in the free introduction course on Headspace, is a good example of why Headspace is vastly more than just a scheduling app. Meditation can be hard, but Headspaces makes it easy to get into.
