Luna Band and Ring: LifeOS: iPhone vs Android

Luna is a comprehensive health tracking ecosystem that comes with a smart ring, a fitness band, and an always-on intelligence layer called LifeOS. Instead of passively displaying data in dashboards, Luna understands your biomarkers and your health goals, and turns them into a personalized plan for your day.

A calendar for your body;
You wake to a day that has already been shaped around the state you are in. Breakfast has a time, your workout planned based on your preferred slot and goals, and a nutrition plan based on your calorie targets and macro consumption. The plan also takes into account what you actually did in the past days and weeks, and learns from your preferences and available resources.


Sleep tracking and continuous vitals;
Understand how well or poorly you slept, with an analysis to meet a single chart. Sleep tracking separates the night into stages, and blood oxygen, or SpO2, along with resting heart rate, HRV and skin temperature are all measured while you sleep, then weighed against your own normal instead of a population average. A figure that looks unremarkable on somebody else's chart gets flagged when it is unusual for you, and every value on the page says whether it was measured, worked out by a stated formula, or estimated.

Manage your health goals;
You describe what you are working towards in your own words, such as running twenty kilometres in a week, and what comes back is a plan with check-ins rather than an empty tracker to fill in yourself. Progress stays honest on the weeks that go badly. The goal also changes what each morning asks of you, so the thing you want and the day in front of you stop being separate conversations.

Track your health 24/7;
Your sleep and stress recorded throughout the day, and your HR recorded every second. Training Load tells you whether recent effort is building you up or wearing you down, VO2 Max estimates aerobic capacity after any outdoor run, walk or ride of fifteen minutes or more, and strain reads as Relaxed, Focused or Stressed as the hours pass. Anything in that history can be asked about out loud, in English, and the reply comes from your own record rather than general advice.

Luna Apps;
You carry only the parts of Luna you use. Cycle Tracker, Calorie Tracker and Circadian switch on when they matter and stay out of sight when they do not, so somebody tracking a menstrual cycle and somebody managing their weight are not looking at the same crowded screen. Calorie tracking holds what you ate and what remains against a target, and explains where that target came from and when recovery moved it. Cycle tracking shows the days to your next period and where the fertile window falls, and the phase you are in shapes the guidance you get that morning.

Track your biomarkers;
Blood work stops being a PDF you cannot read and forget in your inbox. Upload a lab report or blood test result and every marker on it is pulled out, sorted into optimal, in range and out of range, and explained in
