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 terms you can act on. The next panel joins the same record, so you watch an individual marker move across months and find out whether the change you made worked, which is the part a printed result has never been able to tell you.
One Luna, many devices;
You take the ring, the band, or both, and your history stays in one piece regardless. Whichever one you have on reports into the same record, and the header shows its battery level and the time it last synced, so you are never left guessing whether today counted. Training Load is measured by the band. Luna also connects to Health Connect, which brings the workouts and vitals other apps captured alongside everything Luna recorded, and spares you entering anything twice.
I have been using Luna Ring since October 2023 and till September 2024, I have had many issues with the ring. However, the support from the team at Noise and Luna Ring has been amazing. They have constantly stayed in touch and listened to me. I haven’t faced any issues either with the ring or the app for many months now. Why I am stating this, about the people behind the Luna Ring, is mainly that their contributions often gets overlooked by the product they make and support. The ring may not be perfect but they are constantly improving. The app is simple and easy to understand and also upgrading. The UI/UX is easy to understand and navigate. I couldn’t be more thankful and grateful for the ring and the app and the support team. Thanks you!
Life changing but needs improvements

This ring is life changing. I love my watch collection so needed this as I hate wearing anything else on my wrist. This has significantly improved my perception of my health. I sleep better and feel better as previously I did not know I was not getting proper and timely sleep. I workout so it is cool to keep track and improve your heart zones while workout. Previously I did not know I was exerting too much sometimes. Go for it and never look back. App experience is great the support is responsive.
Loved the accuracy

Issue with pairing since last update
ShubhashishPaul
I am not able to pair my Luna ring with my iPhone 15 plus since today morning. The device is visible but when am trying to pair it with iPhone by putting it on the charging pod, it shows pairing unsuccessful again and again. Since today morning I am facing issue with the pairing of the device. First it was not able to sync my data of activity in the morning. I started recording of my badminton activity of 3 hrs but it was not showing any data of the activity. Then I tried to delete the app and reinstall, since then am not able to pair my Luna ring through the app. It’s just 1-2 weeks I bought this device. Please resolve this issue of software glitch or bug whatsoever.
Developer Response
Hey Shubhashish, My sincerest apologies firsthand. Any bad experience is not what we would want for our users. The sync is something that is an identified issue and being worked upon by the team, we will solve this in the next Firmware update. Please bear with us meantime. If you ever, reface this issue till it is solved - please freely reach out on our whats'app support - and we will help you on a case to case basis meantime. For the 'record a workout' feature, it is recommended to wait till the countdown closes before starting the activity.
AI chat attachments: You can now send photos and PDFs to the LifeOS chat.
Notifications: Get your day's Guidance as reminders, and get alerts when your device battery is low.
Performance improvements: Faster, lighter syncing, a more accurate Find Device location, and fixes for app freezes, crashes and meal editing.
