Yes, modestly. A 2024 meta-analysis of 45 randomized trials found that mindfulness apps reduced symptoms of depression and anxiety by a small amount compared with control groups[2], and a 2025 review in American Psychologist by J. David Creswell and Simon Goldberg described the reductions as "modest but consistent"[1]. The larger problem is use. In real-world data, a median of only 4.7% of people who installed a meditation app were still opening it 30 days later[5].
Below is what the research shows about how well apps work and how they compare with in-person courses, plus steps to get more from the app you already have.
How popular are meditation apps?
Meditation apps are the most widely used kind of mental health app by a wide margin. When researchers weighted 27 top-ranked depression and anxiety apps by their monthly active users, mindfulness appeared in 37% of the apps but reached 96% of users, and the two most popular apps accounted for 90% of all monthly active users[4]. The 2025 review, titled "The meditation app revolution", names those two as Calm and Headspace, notes that there are now thousands of meditation apps worldwide, and warns that research lags well behind public adoption[1].
Do meditation apps actually work?
On average they help a little, and the effect holds up in better-quality trials. The 2024 meta-analysis pooled 45 randomized trials. Across 5,852 participants, the effect on depression was 0.24, and across 6,082 participants, the effect on anxiety was 0.28. Both are small effects, and they stayed about the same when the authors kept only larger trials or those at lower risk of bias[2]. In plain terms, the authors estimated that for every 11 to 14 people who use an app, about one more person improves than would have done so without it.
An earlier meta-analysis of 34 trials with 7,566 participants found similar results: small to moderate effects on perceived stress (0.46), depression (0.33) and anxiety (0.28), but no significant effect on general distress or general well-being. Its authors urged caution because the trials were few, varied and at uncertain risk of bias[3].
When apps were compared with another therapeutic option, such as a behavioral activation app, the 2024 meta-analysis found no significant difference either way, though only a handful of trials made that comparison[2]. The 2025 review adds a caveat of its own: meta-analyses of randomized trials may overestimate how much an app helps the general population[1].
What did the largest meditation app trials find?
Large trials of Calm, Headspace and the Healthy Minds Program found small to moderate benefits, but several had high dropout or authors linked to the app's maker.
| Trial | Who took part | What they found | Limits |
|---|---|---|---|
| Calm, 10 minutes a day for 8 weeks[6] | 1,029 employees of a US employer | Less depression, anxiety and insomnia than a waitlist | Only 192 completed every assessment; the first two authors were paid by Calm |
| Healthy Minds Program, 4 weeks[7] | 662 public school employees | Lower distress than a waitlist (d = 0.52 after, 0.33 at 3 months) | Waitlist control; several authors linked to the app's nonprofit developer |
| Healthy Minds Program, 8 weeks[8] | 343 adults with little meditation experience | Larger drops in distress than a waitlist | Only 54% completed a post-test |
| Headspace, used at will for 3 months[9] | 250 first-year university students | Weak evidence of lower distress | Students averaged about 8 meditations in total |
| One 15-minute recording[10] | 2,239 people at 37 sites | Lower state anxiety than listening to a story | Measured once, straight after |
Several of these trials compared the app with a waitlist, which shows only that using an app beats waiting. The 2025 review notes that apps also outperformed active comparisons that were not meant to be therapeutic, such as listening to music[1].
How long do people keep using meditation apps?
Most people stop within a month. An analysis of real-world usage data for 93 popular mental health apps found median 30-day retention of 4.7% for mindfulness and meditation apps, which was better than breathing exercise apps, whose median was zero. People who did keep using meditation apps spent a median of about 21 minutes a day in them, and their use peaked in the morning and at night[5].
The dose is also lower than in classic courses. The 2025 review estimates that active app users practice for 10 to 21 minutes about three days a week, while participants in 8-week MBSR and MBCT courses average about 30 minutes a day, six days a week[1]. In clinical trials of smartphone mental health programs, an average of 24.1% of participants dropped out by short-term follow-up and 35.5% by longer-term follow-up. Dropout was lower in trials that sent reminders[11].
Are meditation apps as good as an in-person course?
Nobody knows yet, because no large randomized trial has compared them directly, according to the 2025 review[1]. The authors point to clear differences. Apps usually lack a teacher and a group, and across digital mental health programs generally, adding human guidance improves both outcomes and engagement. Apps also often leave out parts of courses such as MBSR, including the teaching on stress. In their favor, apps are in theory cheaper and easier to reach, avoiding the scheduling, travel and stigma that keep many people from in-person programs. The review also suggests that people who sign up for intensive in-person courses may have more severe symptoms than typical app users, which could make the two hard to compare[1].
Are meditation apps safe?
No serious harms have been reported, but they have rarely been looked for carefully. The 2025 review found no studies reporting serious adverse events from meditation apps, while noting that adverse effects have not been carefully assessed and that apps often do not screen users with acute mental health concerns[1]. The 662-person Healthy Minds trial found no evidence of increased adverse events[7]. Meditation in general is not free of side effects, though. In a US survey of 434 people who had meditated in any format, 32.3% reported at least one unwanted effect, most often anxiety[12].
What comes next for meditation apps?
The 2025 review expects more personalization and support delivered in moments of acute stress, along with hybrid models that add human coaching, while flagging privacy risks from the data apps collect[1]. Some groundwork exists. Using data from the 662-person Healthy Minds trial, researchers built a model that predicted who would benefit most, and people with more repetitive negative thinking, such as rumination and worry, gained more from the app relative to the control group[13].
Apps that generate a new meditation on request are newer still. Whitespace is a self-guided meditation app that speaks: you bring the intention, and it writes and voices a meditation for exactly that. Like other new apps, it has not been tested in randomized trials like the ones above, so whether generated meditations help more or less than recorded ones is an open question.
How do I get the most out of a meditation app?
Use it the way the successful trials did: briefly, at a regular time, for several weeks.
- Write down one thing you want the app to help with, such as falling asleep or worrying less before work.
- Commit to four to eight weeks, the length of most of the trials above, and pick a fixed time of day.
- Start with about 10 minutes, the daily amount asked of participants in the large Calm trial[6].
- Turn on one daily reminder. Trials that reminded participants had lower dropout[11].
- Once a week, rate the thing you wrote down from 0 to 10, so you can see a small change that you might otherwise miss.
- If nothing has moved after two weeks, switch technique, for example from breath focus to a body scan. Several techniques reduced anxiety by similar amounts in the largest single-recording trial[10].
- If you feel worse, shorten or stop the practice and talk to a doctor or therapist. An app is not a substitute for treatment.
Questions people ask
Do meditation apps really work?
For many people, a little. A 2024 meta-analysis of 45 randomized trials found small reductions in depression and anxiety compared with control groups, and the results held in larger and lower-bias trials. Most trials lasted weeks, so long-term effects are less clear.
Which meditation apps have the most research?
Calm, Headspace and the Healthy Minds Program have each been tested in large randomized trials. Some of those trials were run by researchers employed by or linked to the app's developer, so independent trials matter.
Are meditation apps as good as therapy?
That is not established. In the few trials that compared a mindfulness app with another therapeutic app, there was no significant difference, but the number of studies was low. For severe or persistent symptoms, see a professional.
How long does it take for a meditation app to work?
A single 15-minute recording lowered state anxiety in one large trial, but most app trials measured change after four to eight weeks of regular use.
Why do most people stop using meditation apps?
Real-world data show that only a few percent of people still use a meditation app after 30 days. In trials, dropout was lower when people received reminders, and in-person courses add a teacher and a group that apps usually lack.
