What is the difference between StillMind and Headspace?

The main difference is where the structure comes from. Headspace offers a produced library and structured courses that everyone works through, with a recognisable house style. StillMind builds a multi-session course around a goal you describe, writes each session fresh and anchored to it, and includes private, encrypted journaling in written or voice form. Both give you a path. Headspace’s is produced in advance for everyone, and StillMind’s is composed for you.
