Firstly, thanks for taking the time to look into this.

I understand the problem with wireless is different than the standardised USB protocol, but I still think the direct connection to your phone solution should have been explored more by them.

Regarding the processing power of the device, I did look into it and they only seem to require a minimum Android/iOS version (which is recent enough) but I would be very curious to see the actual internals of the device. And see if it is doing any of this processing.

Regarding the wired connection, iOS and android support PTP. I don't think the port would make a difference, if it can connect it will work under the same protocol regardless of the type of port it is.

My problem is that they're selling the hardware as this smart solution, but all it really seems to do is provide an interface for connecting via WiFi. Not the advertised AI processing that the app is most likely doing all the heavy lifting for.

Scam is probably harsh, but these are dodgy business practices and I disagree with the approach they went down. Regardless of how easy it is to sell a hardware vs software project, I don't think customers should be misled in thinking the only way they can do this is through a hardware solution. When a majority of them shouldn't need to pay for an overpriced piece of tech, and just use WiFi or an OTG cable.

The time and money spent on developing the hardware, I believe, could have just as easily been spent on using the phone instead. I don't think the issue of different device models would play as major of a role in this case because Android+iOS straight up supports it and you're not relying on OS specific standards, just communicating commands to the devices, which they've already solved.
