I've used Insight Timer (a great free option) and was turned off by the cost of Headspace. I decided to take the plunge with the New Year sale Headspace had, though. I do not regret it. The app is great for three reasons: 1) it does an excellent job of nurturing meditation as a habit; 2) the themed packs make meditation less daunting for those who are new to meditation and practicing it for a specific reason (e.g. anger management, focus); and 3) the design is wonderful.
