The short version
Healthy Minds is the research-lab app with a structured framework and a genuinely free model. Waking Up is the philosophical project under Sam Harris with non-dual practice and philosophy lectures. Different approaches to credibility; pick on which matches what you actually want.
When Healthy Minds Program is the right pick
If you want a science-backed meditation framework from a credible research lab — Richard Davidson’s four-pillar training (awareness, connection, insight, purpose) — and a genuinely free app, Healthy Minds is the right shape. The no-paywall model is unique in the consumer space.
When Waking Up is the right pick
If you want meditation as part of a wider inquiry into mind and philosophy, with Sam Harris’ teaching voice plus lectures from neuroscientists and philosophers around it, Waking Up is the right shape. The free-access policy means cost is never the blocker.
