These are the same CGM technologies (Dexcom = Stelo and Lingo = Libre), just aimed at the over the counter "health and fitness" market.

This is not verified info, but I would assume these are either A) the exact same device, just with different marketing B) "binned" production runs that did not meet the accuracy threshold for clinical/prescribed use, but are otherwise "good enough" for someone looking to healthmaxx.

I think they are the same with some software differences. I believe that the sampling rates and tolerances are different. For example, dexcom displays 5 minute samples while the stelo shows 15 minute averages (it internally gets a new sample every 5 minutes like the dexcom). I think the official accuracy is a bit lower for the Stelo as well, although in practice it's probably close to the dexcom.

I can all but guarantee you they are the same device. IDK if they are even binned differently. The software is the main difference.

The "real" device gives you what it measures as your real highs and lows while the OTC devices won't report high highs or low lows.

I have a Stelo (I was curious and diabetes runs in my family) while my wife has the Dexcom.

You can read the Stelo out into XDrip with some settings adjustments, last I checked, so it is just some “light” software tweaks between sensors.

I t Looked into the OTC ones and it does seem they’re binned versions. The failure rate appears to be higher too, which is more acceptable in a non life threatening device.

It also probably gives the companies really valuable data.
