I have been using the app for 3 months now and truth is to say that it is mind-blowing. The content is rich, the teaching impressively precise and the identity in complete coherence with what Headspace is. I subscribed to a premium account after really noticing changes through the Take10 program. I was clearly not into yoga, relaxation, meditation before and I was very surprised by the benefits of meditation on a daily basis. No need to be a hippy to be into meditation, dare to try, you wont be disappointed. Huge support to you Andy, you achieved in making this app one of the best of the Applestore.
