I respect any effort put towards this, seems like a decent project.

Incidentally I used to love the SelfControl mac app, but it started having leaks in its ability to function a while back and now seems unmaintained. The irony being that even though it's open source, anyone who'd be inclined to fix/maintain it would need to not know how it works or sacrifice their ability to use it. Afaik there wasn't anything as effective for mobile.
