Does anyone know what this app is? Here's a picture: https://drive.google.com/file/d/0B3IdETDqOKVtVzNXWnVubXpmY1E/view?usp=sharing

Because here's what I know:

1) I'm a US citizen who was detained by customs for not having a work visa to enter Canada for meetings with a client.

2) They told me they had "blah blah" every right to search my shit, then took my iPhone and went into a backroom.

3) On the plane, before landing, I went through my Apps > Storage and deleted a bunch of apps I was no longer using. I mention this because this list was fresh in my mind.

4) When my phone was returned to me, while waiting, I checked my apps list and found the mysterious app (linked to above) installed in my list!!! What the hell, it wasn't there before. Never seen it before. And it has no name? Nor does it show up anywhere in my home screen.

5) I took this picture and then deleted the app.

6) Woah, wait a second, checked my list again. THE APP IS STILL THERE. I delete it again. And again it won't delete!!!

7) Before I leave (without my passport), I ask the agent what is this app she installed on my phone?? She denies anything, saying she couldn't install anything without my iCloud passport (weirdly specific).

So what the hell? I'm at my friends place, and I've completely wiped my iPhone (it's gone). I'm writing this up wondering what the hell this app was, and more importantly, if Apple has given governments a backdoor ability to instal apps?

Or maybe it's nothing? Any thoughts are appreciated.
