три

tri is a screenless band and an app that turn body data into decisions you can act on. The band captures dozens of signals around the clock; the app distills them into three numbers — sleep, recovery, strain — and tells you what to do with them: when to go to bed, when to train, and when to back off. The band has no screen, so it never interrupts you or asks for attention. All your data lives in the app. Up to 15 days on a charge and up to 30 days of onboard memory without your phone. How it works Longevity. Your body's biological age and your pace of aging — how fast you're aging compared to the calendar. You can see which habits are keeping you young and which are adding years: sleep, steps, heart rate zones, strength training, VO₂max, resting heart rate. Sleep. Every morning you get a sleep score from 0 to 100 and the whole night broken down by stage: deep, light, REM, awake. The app works out how much sleep you actually need today and shows the debt you've built up. The alarm on the band wakes you with a gentle vibration. Recovery. From the moment you wake up, you know what your body is up for today. The score is built from overnight heart rate variability, resting heart rate, sleep and respiratory rate — and it's always measured against your own baseline, never against a population average. Strain. More than step counting: the app measures what your heart and muscles actually took on, on a scale from 0 to 21. Every day you get a strain target based on how well you recovered. Over 100 activity types and our own calorie model. Stress. See how the day went in terms of load: where the spikes were, how much time your body spent at rest, and what led up to it. Behaviors. Log what's going on in your life — alcohol, late caffeine, a workout, screens before bed. The app tests each link statistically and tells you straight: "alcohol in the evening — recovery down 12%, confirmed," or "we see a link, but it may be a coincidence." Nutrition. Take a photo of your plate and the assistant will recognize the dish and count the calories and macros. Your targets are based on your real energy expenditure. Assistant. Ask about your sleep, recovery and training — the answers come from your own data, not from generic advice. And it doesn't just answer: it sets an alarm on your band, creates a reminder, logs a meal. Six personalities to talk to, from a calm doctor to brutally blunt. It remembers the things that stay true about you and takes them into account later. What else is in the app – Details. Heart rate zones, VO₂max, skin temperature, respiratory rate and steps — with history and trends. – Communities. Join a group of friends or colleagues, follow the shared leaderboard, and talk results in the chat. – Progress. Levels, streaks, achievements and coins simply for living your life and wearing the band. MEDICAL DISCLAIMER AND JURISDICTION.
