# Stay younger, longer. Your Apple Watch already tracks your body. Now turn that data into a clearer picture of how you’re aging—and what you can do to help stay younger for longer. The app connects with **Apple Health and Apple Watch** to bring together your sleep, nutrition, workouts, heart trends, body composition, cycle, recovery and more. At the center is your **Health Age**: an estimate based on your calculated **Aging Speed** and more than **50 health metrics**. Your Aging Speed model is informed by insights from **50+ longevity and health research papers**, helping translate everyday health data into one simple question: **Are your current habits helping you stay younger—or aging you faster?** ## Your Health Age See an estimated age for your current health and track how it changes over time. Your Health Age is influenced by areas including: * Sleep and recovery * Nutrition * Strength and fitness * Heart health * Activity * Body composition * Metabolic health * Lifestyle trends Instead of obsessing over individual scores, see how everything works together. ## Your Apple Watch, Reimagined Your Apple Watch collects an incredible amount of information about your body. The app turns that data into meaningful trends so you can understand how your sleep, heart, movement, workouts and recovery may be connected to how well you’re aging. See what’s improving, what needs attention and which habits may make the biggest difference. ## Food Logging in Seconds Eating well shouldn’t require spending your life logging meals. Our ultra-fast food logging workflow lets you record food in just a few seconds. The app analyzes your nutritional patterns and recommends **healthy-aging recipes based on what your diet may currently be missing**, making it easier to decide what to eat next. Track nutrients, spot gaps and build a diet designed around helping you feel and look your best for longer. ## Get Stronger With Age Automatically import supported workouts from Apple Watch or track your gym sessions directly. Log exercises, weights and reps to follow: * Strength progression * Training volume * Workout consistency * Personal gym trends Because staying young isn’t only about how you look—it’s about staying strong, capable and energetic. ## More Than One Health Score Your tracked metrics are also mapped to research-informed insights across: **Heart Health** Follow cardiovascular and fitness trends. **Muscle Health** See how your strength, activity and training are progressing. **Cognitive Health** Understand lifestyle factors associated with maintaining brain health. **Mental Health** Explore how sleep, movement, recovery and nutrition relate to wellbeing. **Hormonal Health** Track lifestyle patterns associated with hormonal health. **Skin & Hair Health** See nutritional and lifestyle factors associated with healthy skin and hair. ## Sleep, Body & Cycle Track supported sleep and recovery data from Apple Watch, follow body metrics and body composition over time, and keep your menstrual cycle alongside the rest of your health data. See your body as one connected system—not dozens of disconnected apps and charts. ## Make Aging Visible You can’t stop time. But you can understand what your body is doing with it. **Track your Health Age. Understand your Aging Speed. Build habits that help you stay younger for longer.** Apple Health and Apple Watch integrations require compatible devices and permissions. Health Age, Aging Speed and related insights are research-informed estimates intended for general wellness and informational purposes. They are not medical diagnoses or substitutes for professional medical advice. And they DO NOT treat, cure or diagnose any diseases.

Understand your body. Shorten the path to answers. The average time from first symptom to an endometriosis diagnosis is six to ten years. Recognising your symptom pattern early — and having it written down — is one of the few parts of that timeline you can actually influence. Endó is a symptom-matching and tracking app for people who suspect endometriosis, or who already have a diagnosis and want to understand what makes their symptoms better or worse. SEE HOW YOUR SYMPTOMS COMPARE Answer a 56-symptom questionnaire drawn straight from published research. Endó shows you which of your symptoms are the ones most strongly associated with endometriosis in that study — and which are not. LOG IT DAY BY DAY Pain, symptoms, mood and flow, with your cycle day and phase alongside them. A minute a day builds a record that's hard to reconstruct from memory. A PLAN, NOT GENERIC ADVICE Your answers about remedies, diet, sleep and daily impact turn into concrete things to try and track next cycle. WALK IN PREPARED Months of structured symptom history in one place: symptom timeline, cycle history, pain patterns, and what you've already tried. ASK ABOUT FOOD AND HABITS Is coffee bad for endo? Should I avoid gluten? Endó's advisor answers everyday questions about food and lifestyle, with sources shown alongside. THE RESEARCH BEHIND IT Endó's symptom matching is drawn from one specific peer-reviewed, open-access study: Goldstein, A. & Cohen, S. (2023). Self-report symptom-based endometriosis prediction using machine learning. Scientific Reports, 13, 5499. The authors surveyed 886 women — 474 with a diagnosis of endometriosis and 412 without — recording which of 56 symptoms each had experienced in the past month. Those published per-symptom frequencies are what the questionnaire is built on. The study was approved by the ethics committee of Ariel University. Its limitations are worth knowing, and we don't hide them: participants were recruited through Facebook groups rather than clinics, and some women in the undiagnosed group may have undiagnosed endometriosis. You can read the full paper yourself. IMPORTANT Endó is an educational symptom-matching and tracking tool. It is not a medical device, not a diagnosis, and not a substitute for professional care. A symptom match is not a result, a risk score, or a prediction. Only a qualified clinician can diagnose endometriosis. Always talk to a healthcare professional about your symptoms.
