I ordered September 25 When nothing happened, I contact support. And they write: “ Unfortunately, there was a problem with the shipment process. We will contact our storehouse about this issue so that this kind of incident won't happen again in the future. We will send you a new Vivoo package on Monday (31st October).” They really shipped and confirmed November 04, a full eight days later. Why?? And when it arrived finally 6 weeks after my order was placed: I do not receive an apology or anything at all and only half my order, one pack instead of the two ordered. This company is pure incompetence and cluelessness. Stay clear off these amateurs!!

Update 2022-10-13: Beware! You can't unsubcribe from their emails, as they keep on sending them, even though I have unsubscribed 3 times already. Could be frauds. Exercise caution! Original review 2022-10-06: This could be a good idea, but before this can be credible it would need calibration and real units of measurement. It does matter a lot in what lighting conditions you scan the test. Just think of day or night, shade or sun. Also it is not enough to calibrate it using white only, as white and white can be very different and usually it is very hard to get/produce true white especially on camera. Also heuristic and/or arbitrary units are not a good idea, as usually they are either meaningless scientifically or they cannot be compared to medical results for example. This is why I would not subscribe or order. But these can be improved and adjusted hopefully, so maybe later. =)
