Mental Health Apps: What They Do, What the Evidence Says, and What's Missing
Mental health apps do four different jobs, and most of the confusion comes from treating them as one. Some help you notice patterns, such as mood trackers and journals. Some walk you through a structured program, such as guided cognitive behavioral therapy (CBT) courses and meditation libraries. Some are AI chat companions. A very small group has passed regulatory review as a medical product, like the prescription apps Germany reimburses (MindDoc, HelloBetter, Selfapy) or the FDA-cleared tool Rejoyn in the U.S. The evidence is real but uneven: apps can support mild to moderate symptoms and help you practice between appointments, but they do not diagnose, they cannot respond to a crisis, and they do not know your history the way a person does. The fourth job, being known by someone, belongs to people: a primary care doctor, a therapist, a coach, or a practitioner you trust.

Four jobs people ask apps to do
Before you download anything, sort what you want into one of these jobs. The first three are what apps do; the fourth is what they do not.
Noticing. Mood trackers, sleep logs, and check-in tools help you see patterns you cannot hold in your head: a rough week after poor sleep, anxiety that spikes before certain meetings. This is useful as preparation for a conversation with a professional.
Practicing. Guided programs, CBT-style courses, breathing and meditation libraries give you structure and repetition. They work like homework: valuable when someone helps you choose it, easy to abandon when nobody checks in.
Chatting. AI chat companions respond instantly at any hour and some people find that comforting. They are not therapists, and several have changed or closed in the past few years, which is a reason not to build your whole support system on one.
Being known. A person who remembers what you said last month, notices when you are not yourself, and tells you when you need more than they can offer. This is the job apps do not do.
Knowing which of the first three you are shopping for keeps you from expecting a meditation app to treat depression or a mood tracker to teach you coping skills.
What the research actually shows
The honest summary is that the evidence is mixed and often thinner than the marketing.
A systematic review in *JMIR Mental Health* looked at randomized controlled trials of Headspace and Calm, two of the best-known meditation apps. It found 14 trials of Headspace but only one of Calm, and only five of the 14 Headspace trials had been preregistered. The authors judged the Headspace evidence promising and the Calm evidence close to absent, and they flagged conflicts of interest in some of the studies (Efficacy and Conflicts of Interest in Randomized Controlled Trials Evaluating Headspace and Calm Apps, JMIR Mental Health, 2022). That does not mean these apps do nothing. It means that a popular app is not the same as a proven one.
The pattern repeats across the field: the strongest results reported in individual trials tend to be for mild or subclinical symptoms, for programs built on established therapy methods like CBT, and for people who finish the program. If a claim sounds like a cure, treat it as marketing.
Prescription apps: the small group with FDA review
A handful of apps have gone through the U.S. Food and Drug Administration. The best-known example for depression is Rejoyn, cleared in April 2024 as a prescription digital therapeutic for adults 22 and older with major depressive disorder who are taking antidepressants. It is a six-week program that combines cognitive exercises with short lessons, and its clearance rests on a 13-week randomized trial with 386 participants (FDA clearance announced by Otsuka and Click Therapeutics, 2024).
Two things stand out. First, it is an add-on to care managed by a clinician, not a replacement for it. Second, it needs a prescription, which means a conversation with a prescriber comes first. That is the model regulators are comfortable with: the app extends treatment, and a person directs it.
What Germany did, and what it teaches
Germany went further than most countries and made it possible for doctors and psychotherapists to prescribe approved apps, called DiGA, which statutory health insurance then covers. Three names come up constantly in German searches: HelloBetter and Selfapy, which offer online courses for conditions such as depression, panic, and stress, and MindDoc, which is known mainly as a mood and well-being companion. HelloBetter and Selfapy are listed in the government's DiGA directory and are reimbursed when prescribed; for MindDoc I found no evidence that it can be prescribed this way.
For a U.S. reader the lesson is not that you should look for these apps. It is that the countries that took apps most seriously still built them as an extension of the healthcare system: a diagnosis, a prescription, a code, and a clinician who knows you are using it. The app is a tool inside a relationship, not a substitute for one.
Where apps stop
Be clear about the limits so an app does not carry weight it cannot hold.
No diagnosis. An app can flag a pattern. It cannot tell whether exhaustion comes from depression, a thyroid problem, medication, sleep apnea, or all of them together.
No crisis response. If you are thinking about harming yourself, an app is the wrong place. In the U.S., call or text 988, or call 911 if you are in immediate danger.
No memory of you. A program knows its modules, not your history. It does not know that mornings are harder since your mother died, or that your sleep fell apart after a move.
No guarantee of staying around. In June 2025 Woebot Health retired its consumer chatbot app, after it had been used by well over a million people (Mobihealthnews, *Woebot Health shutting down its app*). Anything you build on a single product can disappear.
No connection to the rest of what helps. Movement, bodywork, community, spiritual practice, and a trusted practitioner rarely appear in a mental health app.
Why the human step is still the hard one
The most common sequence is this: someone downloads an app, uses it for a few weeks, feels a little better or no better, and then does nothing, because the next step is unclear. Which kind of help fits? A psychologist, a licensed clinical social worker, a psychiatrist, a counselor, a coach, an integrative or holistic practitioner? A directory such as Psychology Today covers licensed therapists, but not the rest. Does your insurance cover it? Is the person taking new clients? Do they work with what you are actually dealing with?
That search is where people stall, and it is not an app problem so much as a map problem. Many of the places that do list people only list one kind: therapist directories show therapists, wellness marketplaces show wellness practitioners, and physician finders show doctors. You end up checking five places and comparing apples to oranges. What is usually missing is a single place where conventional and holistic help sit side by side and you can start from your situation instead of from a job title.
How to choose in ten minutes
Write down answers to four questions.
1. How long has this been going on? A few days usually means watching and caring for yourself. Several weeks with trouble at work, in your relationships, or with sleep is a reason to talk to a professional.
2. What exactly is affected? Sleep, focus, appetite, motivation, panic, rumination. The more specific you are, the easier it is to pick a program or a person.
3. How much structure can I handle right now? A guided program needs regular effort. If that feels like too much today, start with a person.
4. What have I already tried? If the same pattern has returned for years, an app alone is unlikely to be enough.
If you lean toward structure, ask your primary care provider or therapist which programs they trust. If you lean toward being heard, skip to finding a person and use an app as a supplement.
How to bring app data to a real appointment
Whatever you use, make it useful in the room. Screenshot or export a few weeks of mood or sleep data. Write three sentences: what you notice, what you want to change, what worries you most. Tell the professional which app you use and what you have already practiced. Clinicians can only fold your app into your care if they know about it, and the data often speeds up the first conversation considerably.
Privacy and AI companions: a few questions worth asking
Mood entries, sleep logs, and chat transcripts are some of the most personal data you will ever type into a phone. Before you start, check three things. Who can read what you write, and is it used to train a model or to target ads? Can you delete your data and your account, and does the company say what happens to it if it shuts down? And does the app say plainly that it is not a replacement for professional care, or does it imply it can treat a condition?
AI chat companions deserve the same questions plus one more: what does the app do when you say something worrying? A good one points you to human help. If it keeps chatting, that tells you what it is built for. None of this means you should avoid them. It means you should decide on purpose what you share and where.
Where Spine App fits
Spine App does not replace a guided program or treatment. It is built for the question before and beside them: what kind of help fits my situation, and how do I reach a person?
You tell the chat what is going on, in your own words, and you choose whether you want conventional help, holistic options, or both. The results include doctors, therapists, coaches, healers, and holistic practitioners, plus sessions, events, and podcasts. You see profiles with background and open times, compare them in your own time, and book the session through Spine App. Individual profiles carry a verification badge. There are no star ratings; feedback appears as testimonials by invitation. After a session, Spine App asks how it went, which helps you and the platform support you better next time.
If you are not ready to book, you can ask the community a question under "Questions & Thoughts" or browse events. It is free to use until you book, and it works in English, German, and Spanish. Browse practitioners and events
If you are in crisis right now
An app is not the right tool. These are available at any hour:
988 Suicide & Crisis Lifeline: call or text 988, or chat at 988lifeline.org, in the United States.
911 (in the U.S.): if you or someone else is in immediate danger.
Your primary care provider: a sensible first appointment for anything that has lasted weeks, including ruling out physical causes.
If thoughts of ending your life come up, tell a person today, even if it is only the person who answers the phone.
Frequently Asked Questions
Do mental health apps actually work?
Some help with mild to moderate symptoms and with practicing skills, especially programs based on established methods like CBT and especially when people finish them. The evidence is uneven. A 2022 review found promising results for Headspace and almost no trial evidence for Calm. Treat marketing claims with caution.
Can an app replace therapy?
No. Apps can support therapy or help while you wait, but they cannot diagnose, respond to a crisis, or adapt to your history. If symptoms last weeks or affect daily life, talk to a clinician.
Is there an FDA-cleared app for depression?
Yes. Rejoyn was cleared in 2024 as a prescription digital therapeutic for adults 22 and older with major depressive disorder who take antidepressants. It requires a prescription and works alongside clinician-managed care.
What happened to Woebot?
Woebot Health retired its consumer chatbot app on June 30, 2025. The company said it would focus on partnerships with payers, providers, and businesses. It is a reminder not to rely on a single product for support.
What are MindDoc, HelloBetter, and Selfapy?
They are mental health apps popular in Germany. HelloBetter and Selfapy offer online courses that German doctors and psychotherapists can prescribe, with statutory insurance paying. MindDoc is known mainly as a mood and well-being companion. None is designed for the U.S. system.
What should I do if I cannot get a therapy appointment?
Ask your primary care provider for referrals, check whether your insurer lists in-network providers, and consider sessions with other kinds of practitioners while you wait. A guided app can help in the meantime, but ask a clinician which one.
How do I find a real person if I do not know what kind of help I need?
Start with your primary care provider to rule out physical causes, then compare options. Spine App lets you describe your situation and see doctors, therapists, coaches, healers, and holistic practitioners together, with open times and booking in one place.
