Calm App Review (2026): Pros, Cons, Price and a Free Option

What is Calm?

Calm is a subscription app for sleep, meditation and relaxation, made by Calm.com, Inc. Its best-known feature is Sleep Stories, bedtime stories for adults read by well-known voices such as Stephen Fry and Matthew McConaughey. Its US App Store listing counts more than 100 of them, with new ones added every month.

It also has sleep music, nature sounds and soundscapes, plus three daily guided sessions: the Daily Calm with Tamara Levitt, the Daily Jay with Jay Shetty and the Daily Trip with Jeff Warren. There are 7- and 21-day mindfulness programmes, breathing exercises and Daily Move stretching. The UK listing also names Masterclass audio classes with experts and an unguided meditation timer, and says guided sessions come in lengths from 3 to 25 minutes.

It runs on iPhone, iPad, Apple Watch, Apple TV and Android, including Wear OS watches, and it saves your sessions to Apple Health. Calm says it has been downloaded by 180 million people.

Is Calm worth the price?

Calm's website blocks automated readers, so its web prices come from a read of its plans page in a browser on 16 Oct 2026. Apple's and Google's listings give in-app prices without naming the plans, so we don't match them to plans. We re-check every quarter, next by 16 Jan 2027.

For comparison, Headspace is $12.99 a month or $69.99 a year on its US App Store listing (checked 16 Oct 2026). Calm's yearly plan costs a little more and its website has no monthly option, so on the web you commit for a year at a time.

Is Calm free?

Partly. Calm is free to download, and its listing says some programmes and features stay free, with the rest in a paid subscription and no ads. Calm's help centre, which would say exactly what is free, showed us a bot check, so we can't list the free content. A common complaint in recent App Store reviews is that most sounds and stories are locked without a subscription.

The 7-day free trial on Calm's website turns into the yearly plan unless you cancel first. If you try it, set a reminder for day six. The honest ways to use Calm for free are its free content and the trial. For free guided audio with no trial, see a free option below.

Pros and cons

What Calm does well:

• More than 100 Sleep Stories for adults, many with well-known narrators.
• Sleep audio, three daily sessions, short programmes, breathing and stretching, all in one app.
• Guided sessions as short as 3 minutes, says its UK listing.
• It works on many devices, including Apple Watch, Apple TV and Wear OS.
• High ratings on both app stores (below), and no ads, says its listing.

The downsides:

• No monthly plan on Calm's website, so there you pay for a year at a time.
• The free version is thin, going by recent reviews.
• The plan renews on its own. Its App Store listing says auto-renew must be turned off at least 24 hours before the period ends.
• Most of the trials we summarise were run by researchers with ties to Calm (see below).
• Low ratings in recent reviews centre on account access, support and an app update (see below).

What reviewers say

Ratings checked 21 Oct 2026:

• App Store (US): 4.8 out of 5 from about 2 million ratings.
• App Store (UK): 4.7 out of 5 from about 326,000 ratings.
• Google Play: 4.5 out of 5 from about 617,000 reviews, with more than 50 million downloads.

Those averages cover years of ratings. To see what people say now, we read the 450 most recent reviews on the US App Store, from 17 Aug to 19 Oct 2026. 273 gave four or five stars, and sleep came up most in those. 145 gave one or two stars. The complaints we saw most in the low ones:

• Paying subscribers who lost access to premium content, or whose subscription the app stopped recognising, and then waited weeks for support.
• A recent update that moved or broke things people relied on, such as favourites, loops and sleep timers.
• Being charged after a free trial, or trouble cancelling.
• Bugs and playback problems.
• A free version that locks most content, with frequent prompts to upgrade.

Hardly any of the low reviews said the content was repetitive. We couldn't read Calm's Trustpilot page on 21 Oct 2026 because it showed us a bot check, so we don't quote a Trustpilot score.

Does Calm work?

Calm has been tested in several trials. We summarise only trials of adults, and most of those come from one research group with ties to the company. A PubMed search on 21 Oct 2026 was our starting point. These are the randomised trials of the Calm app that we summarise, all in adults:

Across meditation apps in general, the picture is similar. A 2021 meta-analysis of 34 trials with 7,566 people found small to moderate improvements in stress and anxiety scores compared with control groups. Its authors say to read the results carefully because of the small number of studies, uncertain risk of bias and differences between them.

So, does Calm work? For everyday stress and sleep-related symptoms in adults, the trials we summarise point to modest, short-term help, mostly from researchers tied to Calm. The one trial above with an active comparison, podcasts, was a small feasibility study and found no difference. This is not a full list of the research on the app.

Calm vs Headspace

Headspace is the app Calm is most often compared with. Calm leans towards sleep and relaxation, and Headspace towards learning to meditate from scratch. Headspace has a monthly plan and Calm's website does not. See our full Calm vs Headspace comparison.

If you want sound to work or sleep to rather than a voice, Endel generates soundscapes; see our Endel review. For focus music, see our Brain.fm review.

A free option

NSDR.co's library has free guided sessions of non-sleep deep rest (NSDR) and yoga nidra. NSDR is a guided rest practice: you lie down and follow a voice through a body scan and slow breathing, without falling asleep. Most sessions run 10 to 30 minutes. Start with the NSDR sessions, browse the sleep sessions, or try a short breathing exercise like the one above.

It is not a like-for-like swap. There are no Sleep Stories, no celebrity narrators and no daily programme, and NSDR is a different practice from Calm's mindfulness meditation. The research is early. Four small trials have tested NSDR itself, with mixed results. Free to use, always a free plan.

Which should you choose?

• Pay for Calm if sleep is the main reason you want an app, you like being read to, and you will use it most nights.
• Try Headspace if you want to be taught meditation step by step, or you want a monthly plan.
• Start with the trial if you are unsure, and set a reminder before it becomes a yearly charge.
• Start free if money is tight or you only want a few minutes of guided rest or breathing.
