If the thermometer says 39 C/102 F I will want to speak with a doctor about it but that doesn't mean I want to go to the hospital every time I want my temperature checked.

I suspect it has a lot more to do with these lines:

> medical photographers taking photos of suspicious moles and lesions

I.e. it might not be ready enough or validated for an average person snapping their own photo and:

> The images are then transferred to a desktop computer for greater analysis before the tool determines the result

There is more to it than the phone app and it may not be packaged in a way that is currently worthwhile to distribute to home users.

Both of these (and other things) may change with time of course.
