It's available on Mac as well… BUT I made a stupid-ass n00b error and downloaded it from a fully convincing looking fake website with a convincing URL that came up way too high in Google results. Apparently it was a malware distribution site, so ended by doing a full wipe both for my MBP and iPhone, plus full round of password resets – and possibly quite a bit of personal files leaked to Russia 😬 Case in point: don't assume, verify, esp. with apps that require bypassing the Apple security layer upon installing (I assumed it was necessary anyway to distribute an app that can read data off the iPhone).
But back to the camera identification: my rear camera seems to be of the DN8 variant as well. Not sure if that information was worth the 1/2 workday lost plus the invasion of personal data privacy… 😅
