Hopefully, @DrFraser, who has a dog in this fight 
will chime in, since he is promoting it with both a blog post and a YouTube video.

Why the brain, and why now? Temple is developing a wearable designed to sit on the side of the head, near the wearer’s temple. Its aim is to continuously track cerebral blood flow – essentially, how much blood is reaching different parts of the brain over time. That may sound clinical, but the underlying idea is surprisingly intuitive.
If the heart is the engine of the body, the brain is the command center. And just like any high-performance engine, it depends on fuel. In this case, that fuel is oxygen-rich blood. When blood flow shifts, cognitive performance can shift with it – affecting focus, reaction time and decision-making under pressure.In a January podcast conversation, Goyal described Temple’s ambition as building “the ultimate wearable for elite performance athletes,” capable of measuring metrics that current devices cannot. Unlike wrist-worn trackers or smart rings, which primarily monitor heart rate, sleep cycles and activity, Temple is aiming higher up the body [2].
Most wearables today use the heart as a proxy for performance. Temple wants to look at the brain directly. It is a bold claim in a market where companies like Oura, Whoop and Garmin have spent years refining hardware and building trust with athletes. Those devices already offer increasingly sophisticated data on recovery and strain.
Temple’s wager is that the next frontier is not just how hard your heart is working, but what your brain is doing while it happens.
Tracking cerebral blood flow has traditionally required bulky machines in controlled environments. Temple’s challenge is to shrink that into something wearable, comfortable and reliable.
Introducing Brain Flow™
Blood flow to the brain is a proven signal of health and aging. Until now, it’s been hard to measure. Temple tracks Brain Flow, a proxy metric based on this very blood flow to the brain.
All of you, in one place
Track heart rate, HRV, sleep patterns, periods, activity levels, VO2 Max, and more to get an all-round view of your health.
Built for your temple
At the temple, skin is thin and rich with capillaries allowing for better readings. Worn using our gentle medical-grade tapes, Temple is comfortable, easy to wear, and non-invasive.

I am recommending all of my patients go over to this device as it is a technological advancement on the limited approach using brachial blood pressures. I have a lot of patients with abnormal values, and making small interventions, or trialing one class of medication vs. another gives an N=1 approach on exactly what works for your vascular health. As much as we can make logical choices as physicians on what we think is the best choice to optimize a given individual’s numbers, actually getting this detailed feedback on all these parameters gives a better picture. Also interventions like increasing potassium to 3:1 ratio to sodium with sodium being limited to 1500-2000 mg and optimizing Nitrous Oxide all have interesting beneficial effects. However, this detailed data gives us better feedback on interventions than simply a brachial pressure.
@RapAdmin I wonder how much Temple adds simply to knowing central blood pressure and central pulse pressure, along with knowing that your vertebrals and carotids are wide open with no disease on MRA head/neck?

Sadly they are not selling it to the UK as yet.
Looks like it is in development and not on sale anywhere. Nice concept if it works.
It’s a marketing scam. Nothing more than other trackers like Oura, whoops, etc.
They start by a true assertion:
Then they tell you what they really do (Note that Brain Flow is not the Blood Flow they mention above):
Basically they measure the peripheral blood at the temple.
Then they give you the measurements they take in which nothing relates to the blood flow to the brain.
Note that Oura, Whoops and the like already do all that + other things too.
Sadly they don’t do any of that. I’ve put above what they measure and pressure is not in them.
The CONNEQT Pulse discussed above in the thread is based on real science but not this.
Congratulation for them to raise 54M for basically taping an Oura ring to the temple!
A perfect fit for the current pseudo-science environment.
That said there are ways to measure the oxygen saturation in the brain with Functional near-infrared spectroscopy (NIRS) but that’s not the case here.
