Dexcoms Stelo glucose biosensor is promoted as a continuous monitor that helps track glucose in the body.

Dexcom is well-known among diabetics for its CGM.

But how well does Stelo actually work once I put it to the test?

This is not a product meant for those taking insulin.

However, thats not the only jot down of insulin that exists.

Dont worry, the process is shockingly painless, not even a pinch.

you’re able to also purchase more patches through the Stelo site or through retailers likeAmazon.

you might connect the Stelo app toAppleHealth orGoogleHealth so that connect your activity and sleep data.

Theres also a companion app that your healthcare provider can download to view the sensors results.

How did my session go?

Theres an Events tab that you’ve got the option to use to log events throughout the day.

I monitored the glucose recorded through the biosensor versus my blood glucose test to see the difference.

There were, however, some very odd variances at a few points.

Eventually had to remove it on day 11 once the needle itself loosened.

The lack of Android 15 support is also a massive oversight, as it excludes a lot of users.

Luckily, I have an older model, theSamsungGalaxy S10, so I used it just fine.

But to omit such a large audience from such a useful health tool due to OS compatibility issues.
