This app was launched in 2017 and they are still trying to sort out the technology. I would suggest they have at least another 12/24 months before they can even consider marketing it on a global scale. In the meantime they have the paying customers being used as market research for the tech development.
Not sure if I would be too impressed having purchased a product and then be told that we are now in the process of making it function correctly.
