FitYou is the private-by-default biometric tracker built for adults who want real health insights — without surrendering their most personal data to big tech.
The apps you trust with your most sensitive data are built on business models that depend on sharing it.
Big tech turns your weight, heart rate, and sleep into advertising intelligence. You track your health; they track you.
Streaks, badges, and leaderboards are engagement mechanics — not health tools. Adults need data and context, not dopamine.
Research-backed guidance is an afterthought in most apps. You deserve to know the why behind everything we write about.
Three principles that shape every decision we make.
Your data lives on our servers and nowhere else. No third-party sharing. No advertising. Full CSV export whenever you want it.
Data ownershipWeight, waist, BMI, resting heart rate, blood pressure. Comprehensive biometrics with trend analysis, goals, and period comparisons.
Comprehensive metricsEvery recommendation is grounded in peer-reviewed science — with seasonal recipes and meal plans tied to your own biometric data.
Evidence-basedYour dashboard gives you a clear, private picture of where you are, where you've been, and where you're heading.
Set a weight, waist, or resting heart rate target with a deadline. FitYou tracks how close you are — and celebrates when you get there.
Weight goes up after a big weekend? Note it. Hit a goal early? Note it. Every biometric entry, goal, and profile in FitYou can carry its own notes — so the numbers never lose their context.
Works with"Felt bloated after the weekend — waiting a day before logging again."
No backstory, no lifestyle photography, no waffle (unless Belgian). Just ingredients, method, and the occasional tip — tied to your own biometric data.
Clear quantities — no vague "a handful of" nonsense.
Step-by-step instructions. Numbered. Unambiguous.
Only the tips that actually matter — swaps, pitfalls, shortcuts.
Some of the best health and nutrition science rarely makes the headlines, and when it does it usually arrives stripped of its nuance. We will cut through that, drawing on peer-reviewed journals, systematic reviews and the primary literature.
Topics will span metabolism, fasting, longevity, sleep and exercise, even neuroscience and psychology — always with an eye on what's practically useful for someone working towards a healthier weight and a longer healthspan.
