The CNN article talks a bit more about privacy issues. This bit caught my eye:

It’s only available on iOS because Aaron says the app would have to collect information that could ultimately put users at risk to provide the same experience on Android.

I would like to see some details about this. Perhaps there’s a way to work around that problem, even if it meant publishing on F-Droid instead of Google Play.
