Eureka makes it easy to join real medical studies and help solve the world’s biggest health problems—including heart disease, diabetes, cancer, mental illness, healthcare inequities and more. It’s now easier than ever to have a big impact on causes you care about . All it takes to contribute to world-changing research with Eureka is a smartphone and a little bit of free time. Team up with millions of other study participants helping top researchers from research universities like UCSF, Harvard, and Johns Hopkins to answer questions like, “What signals from my smartphone might predict heart disease?” and “How does physical activity affect cancer risk?” Eureka is a non-profit resource built by researchers at the University of California, San Francisco with support from the National Institutes of Health.

Most diet apps are ledgers. You log, they watch, nothing changes. Macro Trainer is a coach. You log, it thinks, and your plan adapts. Set a goal — cut, bulk, or recomp — and Macro Trainer builds your calorie and macro targets, programs your training, then pays attention. Stall for two weeks? It notices, explains why, and proposes the adjustment. Fatigue piling up? It suggests the deload before your joints do. Every week you get a report card: what worked, what slipped, and what to do next.
