Holly Health is a UK‑based digital health company that offers a fully‑digital, personalised coaching platform — via smartphone or tablet — designed to help people build and sustain healthier habits across physical and mental well‑being. The app guides users through modest lifestyle changes — better sleep, nutrition, movement, stress management — using psychology, behavioural science and machine‑learning tools, to make improvements more sustainable and less overwhelming than sudden, drastic “resets.” Holly Health works in partnership with primary‑care providers (notably many GP practices under the NHS) as well as with individuals, and aims to support long-term behaviour change at scale while reducing strain on healthcare services.
