Six readings.
Zero screens.
Wear it day and night. The app turns what the ring picks up into a clear picture of how you move, rest and recover.
Heart rate
Around-the-clock readings, so you can see how your heart responds to a hard day, a workout or a proper night off.
Sleep
Wake up to a summary of when you fell asleep, how long you stayed down and how restless the night was.
Stress
Estimates through the day that help you spot the busier stretches, and when to step away.
Blood oxygen
SpO2 estimates for general wellness, logged next to the rest of your data.
Skin temperature
Readings from your finger, so you notice when things drift from your usual.
Activity
Steps, distance and calories, plus sport modes for walks, runs and training sessions.
Odessa is a wellness device, not a medical device. Readings are estimates and aren't intended to diagnose, treat or monitor any medical condition.
The essentials,
without the premium.
Big-name smart rings charge for the logo, and some charge again every month to see your own data. Odessa doesn't.

Looks like jewellery.
Works like a coach.
Most trackers look like gadgets. Odessa is a smooth band that sits as easily with a suit as it does with gym kit, or next to a wedding ring. Put it on in the morning and forget it's there.
One for you.
One for them.
Match your finishes or choose your own. A considered gift for an anniversary, an engagement, or just because.
Set up in minutes.
Charge it in the case
Drop the ring into its case until it's full. The case slips into a pocket or bag.
Pair it with the app
Download the app on iPhone or Android, turn on Bluetooth and connect in a couple of taps.
Wear it, then check in
Wear it day and night. Open the app whenever you want to see your sleep, heart rate, activity and more.
Everything you need.
Nothing to add on.
The Odessa ring and its compact charging case. No extras to buy, and nothing to unlock.
Get the fit right.
Measure a ring that fits the finger you plan to wear it on, or wrap a strip of paper around the base of that finger and mark where it overlaps.
Measure the inside diameter of a ring that fits and match it to our sizes: 6 = 16.5mm · 7 = 17.4mm · 8 = 18.2mm · 9 = 19.0mm · 10 = 19.9mm · 11 = 20.7mm · 12 = 21.5mm · 13 = 22.2mm · 14 = 23.0mm.
Aim for snug but comfortable: tight enough not to spin, loose enough to slide off. Smart rings are wider than regular bands, so we recommend going up one size for the most comfortable fit.
Wear it for 30 days.
Then decide.
Sleep in it, train in it, shower with it. If it isn't for you, send it back within 30 days. Wrong size? We'll help you swap it.
Choose your ringEverything you're wondering.
Do I need a subscription?
No. The app is free, and every feature is included when you buy the ring. There's nothing to renew.
Can I shower or swim with it?
Yes. It's rated 5ATM, so showering, washing up and swimming are fine. Take it off for saunas, hot tubs and diving.
Can I wear it all day and night?
Yes. It's a smooth, light band made to be worn around the clock, including in bed, so it can track your sleep.
How long does the battery last?
Up to 8 days on a charge. Pop it in the case to top up.
Can I wear it next to my wedding ring?
Yes, though it's thicker than a typical band, so many people wear it on the other hand or on their index finger.
How long does delivery take?
Orders ship within 3–5 business days with tracking, and you'll get your tracking number by email.
What if it doesn't fit?
You have 30 days from delivery to return your ring. Wrong size? Email info@odessaring.com and we'll swap it for free.
