Not to concerned with the Chinese app, but I would change if there is and alternative.
Got mine a few days ago. Connected and inspecting a few rifle bores in less than 5 minutes time. With the app. it connects through WIFI, and as stated above as an answer to my previous question, it serves as it's own "router" You select it as a WIFI network. Cannot remember the name exactly, but its obvious (something scope) Mine shows connected briefly, then show's "no network connection" , but when I open the app the image from the camera displays on my ipad.
Take pics by snapping screen shots, or just move through bore to inspect.
It does have a bit of "latency/buffering" if you move to quickly.
For the price I think it's great.
