Sleep Stories

Calm provides Sleep Stories, which are tales read by well-known voices such as Matthew McConaughey, Stephen Fry, Leona Lewis, and Bob Ross. The stories are intended to help people fall into a deep sleep and cover stories such as Beauty and the Beast and The Lost Grimm Fairy Tale.

Music and Scenes

Songs can include nature sounds and white noise. The music varies in length and can last anywhere between three minutes up to an hour or more.

There is also a scenes feature that plays the sounds that one may hear in different scenes from around the world. Some scenes include "fireplace", where users can hear the low crackle of a fire; "tropical beach", where users can hear waves crashing on the shore; and "summer meadow", where users can hear insects chirping and birds in the distance.

Calm Body

Calm Body includes guided video lessons of gentle stretching and mindful movement claimed to release tension and recharge the mind.

Master Class

Calm is partnered with XpresSpa at major US airports, such as John F. Kennedy International Airport in New York City, Los Angeles International Airport, and Philadelphia International Airport. Users can go to XpresSpa and receive a free luggage tag and ten minute relaxation lounger massage by showing their app to one of the store's employees. Calm products are available at XpresSpa for purchase as well.

Additional Products

Outside of digital offerings, the company sells a sleep mist designed to spray on a pillow to accompany the bedtime story. A book called “Calm” was published by co-founder Michael Acton Smith in 2016 and he told CNBC that other physical products such as books, clothing and potentially a Calm Hotel were part of the company’s vision.


Calm offers a discount of 50% to companies that would like to provide the app to their teams. A company, organization, or group of five or more individuals can purchase the app by selecting the number of people who will be using it. Calm will send a landing page to the company, which can then send it to the team and use the subscription for one year.

There is also an initiative called "Calm Health", which is intended to be used by healthcare practitioners and their clients. It consists of a free subscription for one year for the practitioner and a one month premium trail for their clients. It is available to doctors, dentists, psychologist, and other professionals in the health field. Healthcare practitioners can fill out a form online to sign up for the service and receive more information.

The Calm Schools Initiative allows for any teacher anywhere in the world to access the app for free and share it in their classrooms. The stated goal of this initiative is to onboard 100,000 schools in 2019, intending to reach one million students. Teachers can have access to Calm's expanding children's mediation library and other wellness tools. In order to become a part of this initiative, teachers can visit the company's website and fill out a form. Upon completion and submission of the form, the teacher will be contacted by Calm for further instructions regarding the onboarding process.
