The Real Difference Between Wellness Apps and Digital Therapeutics

Two apps sit side by side on the same phone. One reminds you to breathe slowly before bed. The other was prescribed by a clinician, tested in a randomised trial, and cleared through a regulatory pathway before it was allowed anywhere near a patient. From the home screen, they look almost identical. Clinically, they belong to entirely different categories, and mixing them up matters more than most people realise.

Key Takeaways

• A digital therapeutic delivers a defined clinical intervention for a specific condition and is backed by clinical evidence, whereas a wellness app tracks, nudges or logs without making a treatment claim.
• Many digital therapeutics are regulated as medical devices, so they must clear an evidence bar comparable to a drug or a physical therapy programme before they can be prescribed.
• A JAMA Internal Medicine review of 79 digital therapeutics found that a third had no published clinical studies at launch, which is why the “therapeutic” label alone proves nothing.
• Regulatory clearance and a health system’s own funding decision are two separate gates, and an ordinary wellness app is designed to clear neither.
• The most reliable test for a patient is simple: has the software been evaluated on people with the condition it claims to treat, and is it regulated as a medical device.

That second category is what the field calls digital therapeutics, and the gap between it and ordinary wellness software is widening fast, even as the apps themselves start to look more alike on the surface.

Wellness apps track. Digital therapeutics treat.

A wellness app can log your sleep, nudge you to meditate, or chart your mood over a month. It’s useful, often genuinely helpful, but it isn’t making a treatment claim, and it hasn’t been through the evidence process a treatment claim requires. Digital therapeutics are different by design. They deliver a defined therapeutic intervention, aimed at a specific condition, supported by clinical evidence in the same way a drug or a physical therapy programme would be.

That distinction shows up in how the software gets built. A digital therapeutic isn’t just a feature list wrapped in a nice interface. It’s built around a specific clinical protocol, tested for whether it actually changes an outcome, and often regulated as a medical device rather than treated as general consumer software. The bar for “does this work” is entirely different from the bar most health apps clear.

A structured programme for insomnia is a useful example of what that looks like in practice. Rather than offering generic sleep tips, a digital therapeutic built around cognitive behavioural therapy for insomnia walks a patient through the same structured techniques a sleep specialist would use in clinic, in a specific sequence, over a set number of weeks, with the programme itself tested to show it improves sleep outcomes rather than just user satisfaction with the app.

Why the label gets stretched

Because “digital therapeutics” sounds credible, plenty of ordinary wellness products borrow the language without doing the underlying work. A meditation app might describe itself as therapeutic without ever running a clinical trial. A symptom tracker might claim to “treat” anxiety when what it actually does is help someone notice patterns. The scale of the gap is easy to underestimate: a review published in JAMA Internal Medicine in 2024 looked at 79 digital therapeutics and found that a third had no published clinical studies at all when they reached the market. None of that is necessarily dishonest, but it blurs a distinction that matters enormously to anyone deciding whether to rely on an app instead of, or alongside, a conventional treatment.

The clearest test is simple: has this software been evaluated the way a medical intervention would be, and is it regulated as one? If the answer is no, it might still be a genuinely useful tool. It just isn’t a digital therapeutic in the sense clinicians and regulators use the term, and it shouldn’t be marketed, or chosen, as a substitute for one.

Where digital therapeutics are already changing treatment

Prescription digital therapeutics already exist for conditions including insomnia, substance use disorder and certain mental health conditions, delivered through structured, clinically validated software programmes rather than pills or in-person sessions alone. For patients, that can mean access to a therapeutic intervention without the waiting list that in-person care so often involves, or a way to reinforce a clinician-led programme between appointments rather than leaving the work entirely to memory and willpower.

Who actually decides a digital therapeutic is fit to prescribe

The gatekeeping matters as much as the software itself. In the UK, the Medicines and Healthcare products Regulatory Agency treats software that diagnoses, prevents or treats a condition as a medical device, guidance last updated in February 2025, assessing it against the same broad principles applied to other medical interventions: does the evidence show it does what it claims, and are the risks understood and managed. Health systems then make their own judgement about whether to fund or recommend a given programme, guided by frameworks such as NICE’s evidence standards for digital health technologies, expanded in 2022 to cover AI and adaptive algorithms, rather than marketing claims. That two-stage process, regulatory clearance followed by a health system’s own evaluation, is precisely what a wellness app skips entirely, because it was never designed to clear either bar in the first place.

The evidence bar is the whole point, not an obstacle

It’s tempting to see the regulatory and clinical evidence requirements around digital therapeutics as friction slowing good ideas down. In practice, they’re the entire reason the category is trustworthy. A tinnitus app that has been through structured clinical evaluation can tell a patient, with some confidence, what to expect. One that hasn’t is making a promise it can’t actually back up, however well-designed the interface.

Arch, a UK app and web development company that builds health-tech platforms, has worked on Quieten, a tinnitus relief app designed around this kind of evidence-led approach rather than generic wellness branding. Developers doing this kind of health-tech app development have started treating clinical evidence and regulatory pathways as part of the product brief from day one, rather than something bolted on once an app already has users, which is a meaningfully different way of building software aimed at an actual condition.

What this means if you’re choosing between the two

For anyone deciding whether an app is worth relying on, the practical questions are more useful than the marketing copy. What condition does it claim to help with? Is there published evidence behind that claim, and was it tested on people with that condition specifically? Is it regulated as a medical device, or sold as general wellness software with no such requirement? Answering those questions honestly usually makes the category obvious within a couple of minutes.

None of this makes ordinary wellness apps worthless. A sleep tracker that helps someone notice a pattern, or a habit app that keeps someone consistent with exercise, still has real value. It simply isn’t doing the same job as a digital therapeutic, and shouldn’t be trusted to replace a treatment that has actually been evaluated as one.

It’s also worth asking who is actually recommending the app. A clinician suggesting a specific, named programme as part of a treatment plan is a very different signal to an app store algorithm surfacing something because it’s popular this month. The former usually means someone has already checked the evidence on your behalf. The latter means you’re doing that checking yourself, if you do it at all.

The category is maturing, not just growing

Digital therapeutics are still a relatively young field, and plenty of regulatory and reimbursement questions remain unsettled across different health systems. Some health systems are still working out how to fund these programmes at scale, and some conditions have far more validated options available than others, so the field looks patchy from the outside even where individual products are rigorously tested.

But the direction is towards more rigour, not less, as clinicians, regulators and patients all get better at telling evidence-based software apart from wellness products wearing similar branding. For patients, that maturing is good news. It means the label will keep meaning something specific, rather than becoming a generic marketing term applied to anything with a calming colour palette and a progress chart. The apps that earn the name will keep having to prove it, and that’s exactly how it should stay.

Frequently Asked Questions

Is a digital therapeutic the same as a health app?

No. A digital therapeutic delivers a defined clinical intervention for a specific condition and carries evidence to back that claim, while most health apps track, remind or educate without ever being tested as a treatment. The overlap in how they look on a phone is exactly why the distinction is worth checking.

Do digital therapeutics need a prescription?

Some do and some do not. A subset known as prescription digital therapeutics is authorised for use under clinical supervision, much like a medicine, while others are cleared for wider access once they have met the relevant evidence and regulatory requirements.

How can I tell if an app has been clinically evaluated?

Look for published studies tested on people with the condition the app claims to help, and check whether it is registered or regulated as a medical device. An app that can only point to testimonials or general wellness language has almost certainly not cleared that bar.

Are wellness apps a waste of time?

Not at all. A sleep tracker or a habit app can genuinely help someone notice patterns or stay consistent, which has real value. It simply should not be relied on as a substitute for a treatment that has been formally evaluated as one.

Who regulates this software in the UK?

The Medicines and Healthcare products Regulatory Agency regulates software that diagnoses, prevents or treats a condition as a medical device. Bodies such as NICE then assess whether the evidence justifies use and funding within the health system.
