Headspace vs. Calm - Top Meditation Apps Comparison

5 min read

Headspace and Calm app icons next to each other, with the versus abbreviation in between.

With over 70 million users in more than 190 countries, including 2 million paying users in 2020, there's no doubt that Headspace is one of the most popular health apps when it comes to meditation and stress management.

For its part, Calm counted over 25 million users in 2018, with no less than 4 million paying users in 2020. That same year, during the period of containment attributable to the COVID-19 pandemic, the app reported 120% more user sessions than Headspace (1).

Very similar objectives, but not identical

Although these 2 apps are direct competitors, their functionalities and therapeutic aims differ somewhat.

Headspace offers a wide range of guided meditations with a strong focus on mindfulness, aimed at managing stress and anxiety, and improving sleep, among other things. It also offers content aimed at optimizing concentration and creativity, at work or when studying.

It is said to be ideal for those wishing to learn how to meditate.

Calm also provide a range of features to help manage stress and anxiety, and achieve more restful sleep. In addition to guided and unguided meditations, it offers breathing programs, master classes by experts in the field, and music for sleep, relaxation or concentration.

It is said to be ideal for both novice users and those with an intermediate level of meditation, who often want less structured meditations, or more flexibility in the choice of sessions.

Reputation and cost, as well as the range of translation languages, pratically identical

It's not here that we'll find elements in favor of one or the other.

The reputation of both companies is excellent, as are the user opinions found on the Apple and Google app Stores. The apps are both recognized as easy to use, accessible and with a pleasing interface.

Although the monthly subscription will be slightly cheaper for one than the other, the annual subscription will be at a very similar cost. Both offer a 7-day free trial. Calm offers free content at all times, but it is limited.

In terms of languages, the apps are available in a similar number of languages, including English, French and Spanish.

Finally, we should add that both apps are particularly suitable for the adult population, but also offer content for children.

What does the research say?

Both Calm and Headspace have been the subject of peer-reviewed published studies, including randomized controlled trials (see this article if you'd like to know more about the different types of studies).

A systematic review published in 2022, "Efficacy and Conflicts of Interest in Randomized Controlled Trials Evaluating Headspace and Calm Apps: Systematic Review" (2) looked at the randomized controlled studies available for these two apps: 14 randomized controlled trials were identified for Headspace, while only one was found for Calm. The clinical elements most often measured by the studies were: mindfulness, well-being, stress and depressive/anxiety symptoms. In general, the studies were not powerful enough to detect small or medium-sized positive effects.

The results for Headspace showed that app usage improved depressive symptoms in 75% of the studies that evaluated this parameter. Results were mixed for mindfulness, well-being, stress and anxiety, with 40% of studies showing an improvement in these clinical elements. The only study for Calm showed improvements in stress, mindfulness and self-compassion.

The researchers of this systematic review therefore concluded that research results for Headspace are promising, whereas randomized controlled trials for Calm are in practice non-existent. In this context, it was not possible to compare the 2 apps.

In a nutshell

We've seen that both the Calm and the Headspace apps are among the most popular apps in the field of meditation, mindfulness, stress and sleep, and that many of their features are similar.

Although the Headspace app has been studied more extensively and has therefore been able to prove its clinical effectiveness, both apps deserve a top score of “A” for their evidence and endorsement rating from TherAppX: they are both excellent apps in their niche.
