Insight Timer

The world's largest free meditation library with over 200,000 guided meditations from 15,000+ teachers. Unlike Headspace and Calm, Insight Timer's core library is completely free — supported by optional courses and a timer feature. It hosts meditations from clinical psychologists, neuroscientists, and monastic teachers. The community feature connects meditators globally, and the app tracks your total meditation time alongside millions of concurrent users. For therapists on a budget, it's the default recommendation.
