LifeLeaf vs Dexcom Stelo

Stelo is a cleared glucose sensor for your arm — LifeLeaf reads blood sugar and blood pressure together from your wrist, with nothing to replace.

The honest verdict

Want the most accurate glucose number you can buy without a prescription?

Buy Stelo. It is a cleared continuous glucose monitor and we are not one, and we won’t pretend otherwise.

Want to see blood sugar and blood pressure together, continuously, from one wrist, with nothing to stick on and nothing to replace every fifteen days?

Stelo doesn’t read blood pressure at all. That’s what LifeLeaf is for.

US list prices, checked 9 September 2026. LifeLeaf four-year: $349 + ($99 × 4) = $745. Stelo four-year: $89 × 48 = $4,272, glucose only — it does not read blood pressure at any price. See the working →

Where Dexcom shines

Where Stelo is the right answer

It is a cleared medical device. If you need a glucose number you can act on — because a clinician asked you to watch something, because you are managing a diagnosed condition, or because you simply want the most accurate reading available over the counter — that is what Stelo is built for and what it has been cleared to do.

It reads interstitial glucose directly, from a filament under the skin. That is a different and more direct measurement than anything read optically from a wrist, and no amount of engineering on our side changes that.

If your clinician gave you a monitor, keep using it.

What only LifeLeaf adds

What the arm sensor can’t see

Stelo does one thing very well. It is glucose, and only glucose — there is no blood pressure, no heart rhythm (HRV), no breathing, no sleep. To see your blood pressure alongside it you are buying a second device and reading two apps that don’t share a clock.

LifeLeaf reads both from one wrist, at the same time, continuously. That shared clock is the point: it is what lets you see that the hour your pressure didn’t settle was the hour your blood sugar didn’t either, which is not a thing you can assemble from two separate products.

And there is nothing to replace. No sensor every fifteen days, no reorder, no gap between one running out and the next arriving.

FAQ

Before you compare.

Is LifeLeaf as accurate as Stelo?

No, and we don’t claim to be. Stelo is a cleared continuous glucose monitor that measures glucose directly under the skin. LifeLeaf estimates a blood sugar trend optically from your wrist. Ours is a wellness trend for spotting patterns in your own body over time; Stelo’s is a measurement. If you need a number you can act on, that is what Stelo is for.

Can LifeLeaf replace my CGM?

No. If a clinician prescribed or recommended a glucose monitor, keep using it. LifeLeaf is a general wellness device and is not a substitute for a cleared monitor. Plenty of people wear both — the patch for the number, LifeLeaf for the blood pressure, the heart signals and the sleep that sit around it.

Why is LifeLeaf so much cheaper over four years?

Because there is nothing to replace. Stelo’s cost is a sensor every fifteen days, forever — $89 a month at current list. LifeLeaf is a device you buy once and a subscription: $349 plus $99 a year, which is $745 over four years against $4,272. That is a value and convenience comparison, not an accuracy one. You are not buying the same measurement more cheaply; you are buying a different thing.

The honest question

“Isn’t this less accurate than a CGM?”

What a cleared device is for

Dosing insulin. Diagnosing high blood pressure. Adjusting medication. Those decisions turn on a single number being exactly right, and they need a cleared device. LifeLeaf is not one, does not claim to be, and should not be used for any of them.

What this actually needs

Direction, timing and repeatability — did this breakfast move me more than that one, did the walk flatten the curve, did last night’s dinner cost me the night. Those are comparisons of you against yourself, on the same sensor.

Why that is more useful, not less

A sensor with no needle and no cuff is one you actually wear — all day, every day, with nothing to replace and no expiry. Continuous coverage of two signals beats a slightly tighter number on one signal you stop collecting. And no ring or band reads either signal at all.

Where we are honest about the limit

Absolute values carry more uncertainty than a cleared device. Cuffless blood-pressure error averages near zero but varies more than a cuff, and gets less reliable at high readings. When the signal is thin, we say so rather than showing you a flattering number. That is the product working, not a caveat.

“We are not trying to replace a CGM or a cuff — we are trying to answer a question neither of them answers, which is what your own choices are doing to you, continuously, without a needle.”
