Insight Timer

Insight Timer is a free meditation app and audio library used by around 30 million people. It began as a simple meditation timer released on Apple's App Store in 2009, and was later taken over by the Australian brothers Christopher and Nicholas Plowman, who built it into a platform run by Insight Network Inc., with Christopher as chief executive.

Its library holds more than 300,000 free guided meditations, talks and music tracks from around 20,000 teachers working in over 50 languages, from mindfulness, yoga nidra and breathwork to Buddhist and non-dual teaching, chanting and sound. Alongside the free library there are daily live sessions, multi-day courses and in-person retreats. Member Plus, at US$59.99 a year, adds the courses, offline listening and higher-quality audio and helps keep the library free, and listeners can also donate to teachers directly. Each teacher has a profile page on the app and website, where their recordings can be heard for free.
