Researchers note that most apps have not published any peer-reviewed trial data at all.
A 2022 analysis in NPJ Digital Medicine found that fewer than 3 percent of apps in the mental health category had any published randomized trial evidence.
The US Food and Drug Administration classifies some mental health apps as Software as a Medical Device (SaMD), requiring clinical evidence for specific therapeutic claims.
Apps that position themselves as general wellness tools fall outside this regulatory scope.
The UK’s National Health Service has a digital health evaluation framework called NICE Evidence Standards, which app developers must meet to be listed on the NHS Apps Library.
As of 2025, fewer than 30 mental health apps had cleared this process.
Australia’s Therapeutic Goods Administration updated its guidance on digital health products in 2024 to clarify when an app crosses the threshold from wellness tool into regulated medical device territory.
Consumer advocates have called for standardized labeling requirements that would require apps to disclose whether their features are backed by peer-reviewed clinical evidence before appearing in app stores.

geography, or wait times, according to researchers at the University of California San Francisco.
Apps are not a replacement for medication or in-person therapy for people with severe depression, bipolar disorder, psychosis, or active suicidal ideation, according to
clinical guidance from the American Psychological Association.
For adolescents, results are particularly mixed.

Look for apps that disclose the clinical framework they use, such as CBT, DBT, or ACT, and that link to published peer-reviewed research supporting their specific approach.
Check whether the app was developed with input from licensed mental health professionals and whether it has been tested in a randomized controlled trial with published results.
Be cautious of apps that make broad claims about treating anxiety or depression without citing specific evidence, or that charge subscription fees before any benefit can be verified.
If symptoms are severe or persistent, contact a licensed mental health provider rather than relying on an app as a primary source of support.
