What trust issues did you have with installing it on your new device?
Like all apps, wanted a number of rights cleared for them on my device, and I didn't think something in the testing phase should have gotten privileged access to any area of my phone. At least that's what I remember it was the problem.
Yeah, that was wine shady demands. I think for me, I didn't really see it like an app I wanted to use, so I didn't even bother to check and see if I wanted to mine or not.
