About

GlycanAge

Features

GlycanAge measures your biological age from a simple finger-prick sample. This app is where you follow the whole journey — from ordering a kit to understanding what your result means. YOUR RESULT • Your biological age, shown next to your chronological age • Your glycan indexes, and how they compare with people of your age and sex • The full report, cached on your device so you can read it without a signal • Your history, so a repeat test shows a trend rather than a single number ASK ABOUT YOUR OWN RESULT The built-in assistant answers questions about your result in plain language: what an index means, what tends to move it, what to raise with a clinician. It is an educational tool. It does not diagnose, and it does not give medical advice. YOUR KIT, END TO END • Scan the code on your kit to register it • Follow it from dispatch to the lab and on to your result • Get a notification when your report is ready ORDER AND BOOK Choose the plan that fits how closely you want to track your aging and we'll ship it straight to your door. Register and use the simple finger-prick kit, then post it back in the prepaid envelope. You can also book a consultation with a specialist who will talk you through your result. THE SCIENCE BEHIND THE NUMBER Articles and podcasts on glycans, inflammation and healthy aging from the team and the researchers behind the test. YOUR DATA Your results are health data and are handled as such. Sign-in supports an SMS second factor, the app can be locked with Face ID or Touch ID, and you can delete your account and your data from inside the app. IMPORTANT GlycanAge is a wellness and educational product. It is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. Always speak to a qualified healthcare professional about your health. A GlycanAge test kit is required to produce a result. Kits and consultations are purchased in the app and fulfilled as physical goods and services.
