Are hypnosis apps safe? What a review of 168 apps found
Hypnosis itself is rarely dangerous, but most apps give you little to judge them by. In registered clinical trials of hypnosis in medical settings, the rate of serious adverse events likely caused by it was 0%, and the rate of other adverse events was 0.47%, though several trials didn't report them (Bollinger, 2018). For most healthy adults, the bigger risks with an app are misleading claims, unclear billing and loose privacy.
The best yardstick is a systematic review by a Baylor University team, published online in December 2024 in the International Journal of Clinical and Experimental Hypnosis. It isn't current: the apps were collected before the paper reached the journal in May 2024. A 2013 review of 407 apps shows where things started.
| 2025 review | 2013 review | |
|---|---|---|
| Authors | Scheffrahn, Alldredge, Snyder and Elkins, Baylor University | Sucala, Schnur, Glazier, Miller, Green and Montgomery |
| Journal and dates | Int J Clin Exp Hypn: received May 29, 2024; online December 16, 2024; January to March 2025 issue | Int J Clin Exp Hypn, 2013; apps collected and reviewed June to July 2012 |
| Sample | 679 unique apps found in the Android and iOS stores; 168 met the criteria | 1,455 apps found on iTunes (870 without duplicates); 407 met the criteria |
| Design | Systematic review of app characteristics | Systematic review of iPhone and iPad app store descriptions |
| Main results | Top targets: sleep (56.0%), relaxation or meditation (54.8%), stress (36.9%). 20.2% said the developer or hypnotist was trained in hypnosis; 13 apps (7.7%) claimed evidence-based treatment; 4 reported a clinical efficacy trial | No app reported efficacy testing or being evidence-based; 14% had a disclaimer; 34.6% said the hypnotist was trained or certified |
| Limits | Describes apps without testing them; a snapshot from before mid-2024; paywalled, so figures here are from the abstract | Apple only; store descriptions only; data from 2012 |

Twelve years apart, both teams reached the same verdict. In 2013, "technology has raced ahead of the supporting science." In 2025, apps built on evidence-based protocols "are limited at this time."
Do hypnosis apps actually work?
Some may, but for almost any app, nobody has checked: only four of 168 apps in the 2025 review reported a clinical efficacy trial, and none of 407 in the 2013 review reported any efficacy testing.
A tested app looks like this: in a 2021 randomized trial with 72 patients at a craniofacial pain center, a self-hypnotic relaxation app reduced pain and anxiety in the waiting room more than a look-alike app that played background audio. The trial was small and short, and the lead author owned the company that designed the app, which the paper disclosed.
Recordings also tend to do less than live sessions: in reviews of hypnosis around surgery and medical procedures, live hypnosis showed larger effects, though recordings still helped around surgery (Montgomery et al., 2013). Studies of hypnosis in general, like those in Does self-hypnosis work? and on our research page, don't transfer automatically to a particular app.
How do you choose a hypnosis app? A 6-point checklist
Each check takes under a minute on the app's website or store page. Every "no" is worth knowing before you pay.
- Who is the voice, and what are their credentials? Look for a named person and where and how long they trained. Only 20.2% of apps in the 2025 review said their developer or hypnotist was trained, and the 2013 authors warned that certificates can be bought online, so verifiable training counts for more than the word "certified."
- Is it a recorded human voice or AI, and does it say so? The site or store page should say plainly whether a person recorded the guided hypnosis audio, or software wrote the script or generated the voice. If you have to guess, count it as a no.
- Are its evidence claims specific? "Evidence-based" or "science-backed" should come with a published study of that app, not just of hypnosis in general. In the 2025 review, 13 apps claimed evidence-based treatment, but only four reported a clinical efficacy trial.
- Does it say what it can't do? Look for a plain statement that it isn't medical or psychological treatment, when to see a professional, and what to do in a crisis. In the 2013 review, only 14% of apps had a disclaimer, and the authors called one the minimum.
- Can you hear it before you pay, and is billing clear? You should hear the voice first, and see the price, whether it renews and how to cancel before you enter a card. A free trial that becomes a subscription should say so up front.
- What does it collect? On the App Store, an app's page lists data types it may collect and whether they're linked to you or used to track you (Apple); on Google Play, read the Data safety section. Read the privacy policy before typing health details into any app.
What are the red flags in a hypnosis app?
- A promise to cure a condition, or to work for everyone.
- A claim that one session will "reprogram" you for good.
- Pseudo-scientific explanations: in the 2013 review, some apps said hypnosis works by changing your DNA, "cell memories" or theta waves.
- A "doctor" with no field named: 7% of apps in the 2013 review used the title that way.
- A free trial that renews automatically, with the price or the way to cancel hard to find.
Is AI hypnosis safe?
No one knows yet: as of October 2026, we found no published trial that gave AI-written or AI-voiced hypnosis sessions to listeners and measured safety or effects. The early research mostly looks at AI as a tool for clinicians: a 2026 review written for clinical hypnotists covers uses such as drafting individualized scripts, and keeps the clinician as the "curator of all AI-generated material."
An app doesn't show you whether anyone plays that role unless it says so. That doesn't make AI sessions harmful; the evidence just isn't there yet, either way. Ask whether a person reviews the scripts and whether the voice is synthetic, then apply the other checks.
What doesn't the review show?
- Whether any app helps or harms. It describes what apps reported about themselves, without testing them on people.
- Today's app stores. The apps were collected before May 2024, and stores change fast.
- Possible conflicts of interest. The senior author, Gary Elkins, serves on the scientific advisory board of a company that makes hypnosis apps, according to his Baylor lab's website. We have an interest too: Mind Refuge (mindrefuge.ca) sells self-hypnosis sessions, so weigh our self-check accordingly.
- Whether the checklist predicts results. These checks screen for honesty and basic safety: without outcome data, no one can say whether apps that pass them help more.
How does Mind Refuge measure up?
Mind Refuge is a Canadian self-hypnosis service that builds a personalized 25-minute session from recordings by certified hypnotherapist David Boulet. Every word is his real voice, not AI. You pay once and keep the MP3.

We fail the check that matters most for results, so we don't claim Mind Refuge treats anything. Our comparison page sets other personalized hypnosis services side by side, each checked on its own website or app listing.
Who should avoid hypnosis apps, or check with a clinician first?
Check with a doctor first if you have schizophrenia, a history of psychosis or epilepsy: the NHS says hypnotherapy may not be safe for you. Do the same if you're being treated for a mental health condition, and see a doctor about symptoms that don't go away or keep coming back.
Never listen while driving or doing anything that needs your full attention. Self-hypnosis apps, ours included, are not a treatment; they can complement professional care, not replace it. In a crisis, call or text 988 in the US or Canada, or your local emergency number.
