We defined 'free' strictly: the core experience must be usable indefinitely without payment. Apps with 7-day trials that expire into a paywall did not qualify. Apps with limited free tiers that still deliver real CBT exercises did qualify, with the free-tier limits clearly noted.
Tested across four dimensions: CBT methodology fidelity (does the app teach actual CBT skills — cognitive restructuring, behavioral activation, thought records — versus generic 'wellness'), free-tier completeness (how much real content is behind the paywall), evidence base (published outcomes research), and friction (how often the app nags you to upgrade).
ILTY is disclosed and positioned at #4 with honest caveats: our download is free, but a hard paywall hits after onboarding. We include ourselves because users searching 'free CBT apps' deserve to know we're not strictly free, and because we want to point them to the actually-free options first.
Disclosure
ILTY is the publisher of this roundup. ILTY is included with the explicit honest disclosure that we are NOT free in the strict sense — our download is free but a subscription is required to use the app meaningfully. We rank ourselves at #4 in this list and direct users to the free options ranked above us if free is a hard requirement. Our price checks cover commercial facts only: whether each app still exists, its pricing, platforms and store ratings. They do not re-run the hands-on testing protocol described above, so hands-on impressions date from the original testing round; we say that plainly rather than letting a fresh date imply a fresh test. What the August 13, 2026 check found across the site: Sanvello's consumer app is discontinued (delisted from both stores; sanvello.com no longer resolves), Youper was shutting down on September 30, 2026 (already delisted; it has since shut down), and GG OCD was renamed to OCD.app.
Prices, platforms and availability last checked October 20, 2026 against each app's App Store and Google Play listings and its own website.
The research behind this
Rankings on this page draw on The 2026 State of AI Mental Health Apps, our own study of 15 apps across 8 criteria. Crisis handling was tested by hand: the same four escalating messages typed into every app, screenshots kept. Three of them never produced a crisis number. Every score is published with the reasoning behind it, including ILTY’s, and the rubric is CC-BY if you would rather score apps yourself.
