DoubleVision - Sync Screen with Computer & other iPhones in Realtime 17+

I stumbled across this app and it was described as exactly what I want, an app that would mirror my iPhones screen onto my iPad. Sadly it didn't. I should have known when I opened the app and it immediately asked for full control of my Facebook account. This is NOT GOOD I think to myself, but cautiously proceed anyway. The landing page is a bunch of app bookmarks, some I rarely use and others I don't even have on my iPhone! There are no instructions on how to add an app I DO use and would actually share, only a URL and it's unclear how to save it as one of "my bookmarks"(?). Plus I can only sync my screen to FB friends who have the app!?!? Why would I need this when I could just FB message them with a link? It will play in their newsfeed with no additional app required. It should have been called Facebook screen sharing, it would have saved me 15 minutes.

Before I even tried it, I went to the website mentioned in the description. It was for a different app with no link to this one. Tried it anyway and it launches straight to desktop. No errors, just immediately to desktop. If that's how is supposed to work and only responds to the computer app calling to it, well, can't find the website mentioned to even try to troubleshoot it myself, much less download a copy for my computer. So a big thumbs down, sorry.

Omg I'm so in love with this app! Everything is linked between my computer and iPhone so I don't waste my time trying to remember the website from my computer...this app even sends push alerts so whatever I was doing on the computer is right in front so I don't have to scroll thru all the apps on my phone!
