What does it do
Shows you the impact of your daily effort, sooner.
Most signals available today tell you what happened only after the moment has passed, making it difficult to reinforce helpful habits or discourage unhelpful ones. LifeLeaf closes that feedback gap by showing the impact of your choices immediately—and sooner than lagging measures such as the scale.
A meal moves your blood sugar. A walk moves it back. You see it the same evening.
Cause and effect — now
The same dinner, two ways.
The green curve shows a 10-minute walk beginning at 9:15 PM, reducing the post-meal peak and returning glucose to the steady band around 10:30 PM. Without the walk, the amber curve stays elevated until after midnight.
Cause and effect — over time
The scale is the last thing to move in a GLP‑1 journey.
The steadier days show up in your daily scores weeks before the number on the scale moves during GLP‑1 therapy. This therapy initiation phase is where most people quit — and it's the part only LifeLeaf can show you from your wrist.
How does it work
One device. Nothing pierces the skin.
- Capture
An optical sensor array on the underside send several wavelengths of light into the wrist and capture what comes back, continuously. No cuff to strap on. No needle discomfort. No sensor to replace.
- Clean
The hard part isn’t capture — it’s separating the real signal from the noise of everyday life like movement and daylight. That’s the work our scientists focused on over the past 10 years, with eleven patents granted.
- Decode
AI models trained on real-world data, not lab conditions, turn the cleaned signals into numbers and scores you can act on.
Nothing to calibrate. No readings to enter. Put it on — that’s the setup.
Optical sensor array
LifeLeaf just needs your wrist.
Oura needs an arm sensor.
WHOOP can’t see blood sugar.

Is it accurate
Demonstrated in published clinical research.
- Mayo Clinic
- Cleveland Clinic
- AMCR Institute
70,000+ paired readings across seven clinical sites — every one of them taken side by side with the reference devices clinicians already use, including a glucose monitor and an arterial line in an operating room.

And what it isn’t
The app says so. It tells you when the signal isn’t clear instead of inventing a number. Honesty is a feature.
Is it for me
Four journeys. One wrist.
The same device, reading for four different reasons.
Pursuing Longevity
Guess less about your own body. Two signals, continuous, between lab visits.

Insights. Actions. Progress.
Three screens, in the order you meet them.
Insights
Daily scores and the vitals behind them — blood sugar, blood pressure, heart rhythm (HRV) — today and over the months.
Actions
One thing to try today, why it likely helps, and the habits worth building on.
Progress
Proof it's landing inside a week, not a quarter — and your age trend as the habits hold.
What is the cost
A quarter of the price people pay today.
To see blood sugar and blood pressure together.
- $15–25 a month. One device — LifeLeaf.*
- Or a CGM sensor, paired with an Oura ring or a WHOOP band.
- That’s about $89 a month for the CGM, forever — plus the device.†
You keep more than $2,100 over two years.
More than $4,200 over four.†
| Over | LifeLeaf* | Oura Ring 5 + CGM† | WHOOP Life + CGM† |
