Research note
Do hypnosis apps work? What studies of app-delivered and recorded hypnosis show
Some do, for some uses. The strongest evidence is for irritable bowel syndrome: in a randomized trial of 240 adults, 81 percent of people using the Nerva hypnotherapy app had a meaningful drop in symptoms versus 63 percent with a similar program without hypnosis. Recorded self-hypnosis at home also helped children with abdominal pain nearly as much as a therapist after a year. But in a 2026 head-to-head trial, a self-guided smartphone program helped fewer adults than in-person therapy, and for stress, sleep, and habits the app evidence is mostly observational. The biggest practical problem is that most people stop before finishing.
The evidence at a glance
| Use | Best evidence | What it found |
|---|---|---|
| IBS, adults, app vs active control | Randomized trial, 240 adults (Anderson and colleagues, 2025) | 81% vs 63% met the main symptom goal with the Nerva app |
| IBS, adults, app vs in-person therapist | Randomized trial, 230 adults (Snijkers and colleagues, 2026) | Pain response 33% with the app, 48% in person, 22% with education only |
| Abdominal pain, children, home recordings vs therapist | Randomized trial, 260 children (Rutten and colleagues, 2017) | At one year, 62% vs 71% treatment success; recordings judged non-inferior |
| Stress, adults, general self-hypnosis app | Observational study, 84,395 users (Tran and colleagues, 2025) | Stress ratings fell after each session; no control group |
| Self-hypnosis in general | Review of 22 randomized trials (Eason and Parris, 2019) | Medium-to-large effects across varied conditions |
Where the evidence is strongest: IBS
Gut-directed hypnotherapy is one of the best-studied uses of hypnosis, and it is also where apps have been tested most rigorously.
An app beat an active control. In 2025, researchers randomized 240 adults with irritable bowel syndrome to 42 daily sessions of the Nerva app or to a matched digital program without hypnotherapy. By the end, 81 percent of the Nerva group had a clinically meaningful drop in symptom scores, compared with 63 percent of controls, and 71 percent versus 35 percent had at least 30 percent less pain (Anderson and colleagues, 2025).
But a therapist did better than a different app. In a 2026 Dutch trial, 230 adults with IBS were randomized to 12 weeks of in-person hypnotherapy, a self-guided smartphone hypnotherapy program, or online education. Pain responded in 48 percent with a therapist, 33 percent with the app, and 22 percent with education. The app could not be shown to be as good as in-person therapy (Snijkers and colleagues, 2026).
Recordings worked well for children. In a trial of 260 children with functional abdominal pain or IBS, self-hypnosis practiced at home with recordings was judged non-inferior to sessions with a therapist after one year, with success in 62 percent versus 71 percent (Rutten and colleagues, 2017). Right after treatment the gap was larger, which suggests home practice may take longer to catch up.
Put together: a well-designed hypnosis app can help many people with IBS, and is better than nothing or education alone, but on average a skilled therapist still does better.
Stress, sleep, and habits: thinner evidence
For general uses such as stress, sleep, confidence, or quitting smoking, app-specific evidence is weaker.
- Reveri published data from 84,395 users showing stress ratings dropped from before to after each of the first ten sessions, with larger drops for interactive sessions and for more hypnotizable users (Tran and colleagues, 2025). Without a control group, it shows that people feel calmer after a session, but not how much is due to hypnosis rather than a quiet break.
- Smoking apps have mostly been evaluated with user surveys. For example, a survey of 120 users of Mindset Health’s Finito app found about half reported quitting, but respondents chose themselves and an author consulted for the company (Alldredge and colleagues, 2024).
- Self-hypnosis in general has more support. A review of 22 randomized trials of self-hypnosis found medium-to-large effects across conditions such as pain and anxiety (Eason and Parris, 2019), though not specifically for apps.
So for these uses, a hypnosis app is a reasonable, low-risk thing to try, but the claims in app-store listings usually go beyond what has been tested.
The real problem: finishing
The trials above measure people who were enrolled and followed. Real-world use looks different. In an analysis of 2,843 people who started the Nerva program on their own, only 9 percent completed all 42 sessions; among finishers with data, 64 percent responded (Peters and colleagues, 2023). A separate analysis of about 15,000 Nerva users found 31 percent persisted with the program (Simicich and colleagues, 2024). Mental health apps in general lose most users within weeks (Baumel and colleagues, 2019).
The practical lesson: an app that works in a trial only works for you if you keep using it. Pick a time of day, keep sessions short, and treat the first two weeks as the hard part.
Why results vary from person to person
People differ in hypnotizability, the ability to become absorbed and respond to suggestion. By convention, researchers often label the top and bottom 10 to 15 percent of scorers as highly and low hypnotizable (Lush and colleagues, 2018), and in the Reveri data more hypnotizable users reported larger drops in stress. If one app’s style does nothing for you, a different induction, more practice, or a live practitioner may still help. Our guide to what hypnosis feels like explains hypnotizability and safety in more depth.
How to choose and use a hypnosis app
- Match the app to the job. For IBS, choose a program tested for IBS, alongside your doctor. For general relaxation or sleep, a broader self-hypnosis app is fine.
- Check what the evidence is for. A study of an app for one condition does not show it works for another.
- Commit to two weeks. Use the same time each day and judge it after the trial period, not after one session.
- Watch for warning signs. Stop and seek advice if sessions leave you distressed. Hypnosis is not recommended without professional guidance for people with psychosis or in acute crisis.
- Consider a live practitioner if an app does not help after a fair trial. See our guide to online hypnotherapy.

Where Manai fits
Manai is not a hypnotherapy program and has not been tested in clinical trials. It is a personal practice app that can create self-hypnosis recordings: you describe the situation and the suggestions you want to hear, and Manai writes the script, narrates it with your chosen pauses, and saves it to replay. Some people find a recording made around their own words easier to keep using, which matters given how many people stop. Our step-by-step guide on how to use a self-hypnosis app covers a first week of practice.
Original illustrative request, not a tested example:
Create a ten-minute self-hypnosis recording for falling asleep after night shifts, when it is light outside. Use a slow progressive relaxation as the induction. Two suggestions about letting the daylight be background, in second person. Leave long pauses. Do not count me back up at the end.
You can create a self-hypnosis practice in Manai on the free plan and read the script before any audio is made.
Frequently asked questions
Are hypnosis apps effective?
Some are, for some uses. A hypnotherapy app for IBS beat an active control in a 240-person randomized trial. For stress, sleep, and habits, most app evidence is observational. On average, a skilled live practitioner still does better than a self-guided app.
Can a hypnosis app replace a hypnotherapist?
For everyday relaxation or sleep, an app is often enough to start. For medical conditions, evidence is mixed: one IBS app worked well against an active control, but a different self-guided program did worse than in-person therapy in a head-to-head trial. Discuss conditions with your doctor.
How long does it take for a hypnosis app to work?
Programs studied for IBS run about six to twelve weeks of daily or near-daily sessions. Many people feel calmer after a single session, but lasting changes in symptoms or habits usually need weeks of regular practice.
Why does hypnosis work for some people and not others?
People differ in hypnotizability, the ability to become absorbed and respond to suggestions, and in how well a particular style suits them. Expectations, practice, and finishing the program also matter. If one approach does nothing, a different induction or a live practitioner may help.
Are hypnosis apps safe?
For most healthy adults, listening to self-hypnosis recordings is considered low risk. They are not appropriate on their own for people with psychosis or in acute crisis. Stop if a session leaves you distressed, and speak with a professional.
