What it sees.
Five signals, one wrist, no needle and no cuff.
Signal 1 of 5
Blood sugar
Where you sit in your range, and how the day moved you.
What LifeLeaf shows you
72%In range
of the last 7 days
Watch a meal move it. Watch a walk move it back.
What it can’t tell you
- It shows blood sugar trends, not diagnostic readings.
- It can't tell you whether you have a condition.
- When the signal isn't confident, LifeLeaf says so.
Signal 2 of 5
Blood pressure
An hourly average through the day, and where it's heading.
What LifeLeaf shows you
141/85mmHg
Systolic trending above baseline · watch
A cuffless reading varies more than a cuff does. So, we display the hourly average.
What it can’t tell you
- Not a cuff, and not a spot clinical reading.
- It can't tell you whether you have a condition.
- If your clinician asked you to measure using a cuff, keep measuring that way.
Ambulatory Cardiovascular Profile will be available in early 2027.
Signal 3 of 5
Heart rate, rhythm & HRV
Your resting heart rate and HRV are the important ones.
What LifeLeaf shows you
- Your resting rate, and how it drifts across days.
- Variability, against a typical range for your age.
- Variability drops before you feel it.
What it can’t tell you
- It isn't an ECG and doesn't look for irregular rhythms.
- It isn't an alert system, and it won't warn you.
- If something feels wrong, that's a question for a clinician.
Signal 4 of 5
Respiration rate
Quietly useful. It shifts before anything else does.
What LifeLeaf shows you
- Your breathing rate, through the day and overnight.
- A steady night looks steady here first.
- It moves when something's changing, often before you notice.
What it can’t tell you
- It isn't a test, and it isn't an alarm.
- It doesn't tell you why the number moved.
- If you feel unwell, don't wait for a wrist device.
Signal 5 of 5
Oxygen saturation
A steady overnight reading is one less thing to wonder about.
What LifeLeaf shows you
- Overnight oxygen saturation, read from your wrist.
- Where last night sat against your own usual range.
- Shown as a night, not as a moment.
What it can’t tell you
- It isn't a medical oximeter. A wrist isn't a fingertip.
- Cold hands, movement and fit all move this number.
- If you feel unwell, that's a question for a clinician.
