THE PRODUCT IDEA
Your body does not reset at midnight.
Neither should the way you read it.
A single number can tell you what happened. Ring Pro is designed to show how today relates to the days before it—and which change deserves your attention.
It begins with signals captured continuously from the finger. AIVELA then compares those signals with your recent patterns, looking for the difference between ordinary fluctuation and a shift that may be meaningful for you.
Three sensing systems.
One continuous picture.
Each sensor answers a different part of the same question: what is changing in your body, and what context makes that change useful?
HEART AND OXYGEN
Multi-wavelength PPG
Green, red, and infrared light follow changes in blood flow from the finger.
Signals supported
Heart rate, HRV, and blood oxygen insights.
Why it matters
Heart patterns become more useful when read beside sleep, stress, and recovery.
BODY TEMPERATURE
Digital temperature sensor
Tracks subtle shifts in skin temperature from the finger across day and night.
Signals supported
Nightly temperature trends and deviation from your recent range.
Why it matters
Temperature shifts can reveal recovery changes before you feel them.
MOVEMENT
6-axis IMU
Captures movement, orientation, and activity from the ring throughout the day.
Signals supported
Steps, activity intensity, and sleep movement.
Why it matters
Motion context helps separate rest from exertion and adds meaning to other signals.
TOUCH AND CONTROL
20 × 20 OFN Touch
The optical touch surface reads precise finger movements, recognizing taps, presses, and directional swipes.
Gestures supported
Taps, presses, and swipes in multiple directions.
Why it matters
Control music, take photos, scroll through short videos, and turn pages—without reaching for your phone.
YOUR PERSONAL BASELINE
The reference point is not everyone else.
It is you.
AIVELA learns the range your recent patterns tend to follow. Today is then viewed against that range, so a familiar number and an unusual change are not treated as the same thing.
01 Establish your usual
Recent nights and days form an evolving personal reference.
02 Place today beside it
Current signals are compared with what has been typical for you.
03 Surface what changed
The app highlights the shifts that deserve context—not every fluctuation.
A DAY WITH AIVELA
The insight changes
as your day changes.
Move through the day to see how the same personal baseline can support different decisions.
AIVELA SUGGESTS
Your recovery is close to your usual range. Keep today balanced and check in again if stress begins to rise.
START WITH CONTEXT
See how last night shaped today.
Sleep duration, timing, resting heart rate, and HRV are viewed together before the day begins.
See how last night shaped today.
Sleep duration, timing, resting heart rate, and HRV are viewed together before the day begins.
Keep movement in context.
See how current movement relates to your usual range before deciding what to do next.
Notice the shift, not every fluctuation.
Compare your afternoon signals with your personal baseline and make space for what changed.
Close the day with context.
Bring the day together and see which patterns are worth carrying into tomorrow.
