If they call them novelty devices in print. Or say they are accurate less than x% of the time. They are absolved of guilt. A good reason to read the fine print mentioned.

This is accurate less than 17% of the time when used for general health accessment. Probably almost never accurate for blood glucose measurement.

I tried it this morning. It said my skin age is 35. My BMI is 22.1, my pulse 69, BP 109/65

I am 73, my BMI is 28, my pulse 44, my BP 124/80.

It determines this by a face scan.

I didn't ask for anything else. I refused to pay. And deleted the app.

Not accurate at all.

My youngest son is terrified of needles. He wants to buy a device that goes on the end of your finger like an oximeter, that is supposed to test bs. I told him if he bought something like that I would bust it as they aren't accurate.

Why are these companies allowed to sell devices that could cause death and why aren't there stricter regulations in place?

It is a piece of crap. It isn't even close most of the time.

It is pseudo-science at best.

It can only tell general health from pictures It takes of your face.

You will die if you use it for treatment decisions. Especially If you are on insulin or sulfonureas.

Do not believe anything it tells you.

The Calmia app isn't something that comes up in available resources, so it's hard to speak to its accuracy specifically. However, this is a great question worth exploring carefully, especially when it comes to blood sugar tracking.

Here's what's important to know about apps and devices that claim to measure blood sugar without a finger prick or CGM sensor:

- The FDA has warned against using devices that claim to measure blood sugar without piercing the skin
- Studies on non-invasive blood sugar tracking show wildly inconsistent accuracy — some devices are only accurate about 19% of the time
- Inaccurate readings can be genuinely dangerous, potentially leading to too much or too little insulin

A DiabetesTeam member put it well: "They are not accurate, and it is just an easy way to get yourself in trouble. Stick with the blood sticks. Remember, if it sounds easy or too good to be true, it should be a hard pass when the device is supposed to help you make life decisions." If the Calmia app works alongside a CGM or glucometer rather than replacing one, it may be more reliable. It's always worth checking with your healthcare provider before trusting any new app with decisions about your diabetes management.
