Calm is a software company based in San Francisco, California. It produces meditation products, including guided meditations and Sleep Stories. Calm was founded on May 4, 2012 by Michael Acton Smith and Alex Tew. Tamara Levitt became the Head of Mindfulness in November 2014 and is one of the app's primary narrators.

Calm produces meditation products, including guided meditations, a book, narrated Sleep Stories, and health and meditation videos. Their primary product is the meditation app, available on iPhone and Android devices.

The app features both meditation tools and sleep aids. Every June 21, International Yoga Day highlights the practice of what some see as a fitness activity, but others believe to be a much more spiritual undertaking. Since the outbreak of the coronavirus, many yoga studios have closed their doors, resulting in yoga and meditation fans having to resort to home practice through online courses and yoga apps.

The app Calm has been the most downloaded app in the section, with 5.26 million downloads on Google Play from January to June 18 of this year, according to Priori Data. The app includes exercises and courses to reduce stress and anxiety through music and breathing programs.  The ranking continues with the apps Headspace (2.08 million downloads) and Meditopia (1.89 million). The first app purely dedicated to the physical practice of yoga comes in rank 4: Yoga Go – Train at Home (1.39 million downloads).
