PulseRing™ Smart Ring for Sleep, Stress and Recovery

You slept eight hours and feel like you slept four. Your focus dies at two in the afternoon and the coffee stopped helping weeks ago. You are guessing at the cause, and you cannot fix what you cannot see. PulseRing is a smart ring that ends the guessing: it tracks your sleep stages, heart rate and blood oxygen from your finger, all day, with no subscription to see your own data.

How this smart ring works

Wear it. That is most of the job. An optical sensor in the band reads your pulse through your finger. At night it records light, deep and REM sleep. By day it logs heart rate and activity. Open the app and it syncs over Bluetooth into daily and weekly charts you can read in ten seconds. Magnetic charge in two hours, then days of battery. No nightly charging ritual.

In practice

Monday the app shows five hours of real sleep inside your “eight hours in bed.” That explains the fog, and tonight the laptop closes earlier. Wednesday your resting heart rate has climbed all week: deadline stress, made visible. On a trip it goes where a watch will not, through security and under a shirt cuff, and at 5 ATM it survives the pool and the shower. Bonus for creators: a gesture mode triggers your phone camera remotely from the ring.

Features

• See why you are tired. Automatic sleep staging: light, deep, REM (scored nightly in the app).
• Catch stress early. Continuous heart rate with resting trends (interval set by you).
• Forget you wear it. 6.8 g titanium alloy, lighter than most wedding bands.
• Wear it everywhere. 5 ATM water resistance.
• Charge and forget. Magnetic charging, 10 to 15 day standby.
• No toll booth on your data. Free app (iOS 11+, Android 6+), every feature included, no subscription ever.

Honest notes

Sleep detection is automatic, so the ring estimates when you fell asleep and occasionally misjudges the edges: weekly trends are its strength, not minute-perfect timestamps. Heart rate can drift during hard workouts; at rest and asleep, where recovery tracking happens, it is solid for this sensor class. The app is simple, not flashy. And this smart ring is a wellbeing tracker, not a medical device.

Get your size right

The one thing worth two minutes before ordering. Wrap a paper strip around your finger, mark the overlap, measure in mm, divide by 3.14, pick the closest diameter below. Measure at the end of the day.

Silver and Gold: all sizes. Pink: sizes 8, 9 and 10 only.
