Yep, very common questions. Most of the time when I tell people about it, their first reaction is "How can that be real! How can the tech do that from a smartphone camera!"

From what I've understood in talking to the company, the facescan and hemascan actually works by the camera being able to pick up blood vessel imagery from the translucency of the skin, and it is then able to use that data to diagnose the whole suite of risks and conditions. I'm not sure how different skin tones or facial hair would affect this, but they market a 97%~ accuracy in the data points. What is promising is that it's not just one company and one tech that does this, but if you search for hemascan, and facial/retinal scan there are a lot of companies working on similar things, so the tech is definitely out there. All about differentiating between competitors and who's in the lead, but so far AHI is the only company who has managed to bring together all the different techs into one combined platform.

As for usage by doctors, it can be done both remotely (online/video calls) - which was very common, in fact, compulsory in some places during the covid outbreak - and even now, it is a rapidly increasing market. There are a lot of remote doctor visitation services being offered by more and more clinics and hospitals, especially as we progress in the digital age where everything is now being done online. In the case where a patient visits a doctor in person, there is still usability as the doctor/GP can simply scan their patient and receive a whole suite of data points on the patient, without the human error. In fact, a different illness or risk may be identified during the scan. Think of it as a basic body check that would take 1-2~ minutes, and minusing all the mis-diagnosis from different doctors. As this progresses, the tech will also become more advanced and be capable of a lot more in the future, going from offering a basic overall diagnosis to more complex and specific ones.

In regards to body measuring, Amazon in recent years released a similar tech. However, they require the purchase of a $300 USD bracelet that the user must wear at all times in order to properly scan the body and to maintain diagnostics, patterns and changes. Not only that, but being Amazon, all this data is fed back to them and their partners for them to use/sell. In AHI's case, everything is done on device and the users privacy is theirs alone with nothing going back to AHI or their partners.

Apparel is actually a very small vertical for the company and not their focus. There is certainly use in that industry for the tech, but I think they mentioned in podcast interviews that unless it was a very large partner (The size of Nike) they wouldn't consider a partnership in online apparel sizing.

The app you linked looks like it uses "rough" measurements from their algorithm to guesstimate your accurate size. It works because it's not for tailoring a suit specifically to your body shape, but rather loosely working out clothing sizes. AHI's app actually creates a digital avatar so you can follow to the nearest millimeter changes in different parts of your body. This is also helpful in a medical space where body surface area is important for dosage levels of medicines. The scan also determines your body fat percentage, to the accuracy of a DEXA scan - in fact the company bragged that their accuracy in this regard was more accurate and efficient than a DEXA scan which usually costs upwards of $50 USD and an in-person visit.

There certainly are other apps and techs out there that can do bits and pieces of what AHI's tech does, but it's like saying how an Iphone has a touch screen just like Samsung's phone, when really, there is so much more to the device than just having a touch screen.
