Insight Timer is partly known for its customizable timer-only option that allows you to choose different bell sounds, durations, and presets. In addition, Insight Timer sources over 2,800 meditation teachers for different courses (including Bluth, Brewer, and Salzberg) and provides full biographies for each one — the caveat is that, while the app is free, most of these in-app courses will cost you $5. The variety of courses can be a tad overwhelming when trying to decide where to start, especially if you’re new to practicing; that, coupled with the timer-only option that makes the app famous, makes Insight Timer more suited for experienced meditators.
