UCSF Eureka Research vs Macro Trainer

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 fitness 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. Sleep and energy entries help you reflect on recovery. Every week you get a report card: what worked, what slipped, and what to do next. COACHING THAT ADAPTS • Separate coach conversations with saved history and draft recovery • A weekly report card with nutrition and workout scores • Automatic plateau detection with one-tap macro adjustments • Optional deload proposals for you to review before applying • GLP-1 companion mode with protein-first targets, a dose diary, and appetite-aware coaching • Six coach personalities — from warm and nurturing to zero-excuses — or build your own. Chat runs privately, right on your device. LOGGING IN SECONDS • Snap a photo of your plate: your coach names each food and estimates the portions, you confirm, and it's logged as real servings • Or just say what you ate, typed or dictated — "two eggs, sourdough toast with butter, black coffee" — and your coach splits it into foods and sizes each one for you to check before it's logged • Over a million foods stored on the device — search is instant, even with no signal at the gym or the grocery store • Barcode and nutrition-label scanning • Smart recents and planned meals for one-tap repeat logging PROGRESS YOU CAN READ • A weight trend with 7-day smoothing, goal projection, and body-composition breakdowns • Recovery estimates and recorded biometrics, with explanations and sources for HRV, heart rate, sleep, blood pressure and ketones • Adherence trends that connect what you did to what happened TRAINING BUILT IN • Progressive workout programs with targets that follow your plan • Set logging designed for the gym floor: big controls, rest timers, volume tracking • Missed a session? Pick it up where the plan left off. EVERYWHERE YOU ARE Native on iPhone and iPad. Your data syncs with Apple Health. SPEAKS YOUR LANGUAGE Macro Trainer is at home in 34 languages — the interface, your weekly report card, and the coach itself. It follows your phone's language, or whichever one you pick.
