About Daylight (DaylightRx)
Daylight, from Big Health, is a self-guided smartphone program that teaches cognitive behavioral therapy skills for worry and generalized anxiety through short voice-guided, animated sessions and practice techniques. DaylightRx, the prescription version, received FDA 510(k) clearance in 2024 for adults 22 and older with generalized anxiety disorder, as an add-on to usual care; Medicare billing codes have existed since January 2025. The non-prescription Daylight app is available only to people with an account through an employer or health plan. Two Big Health-funded randomized trials found larger anxiety reductions than a waitlist and than psychoeducation.
