Just 2 suggestions

This is an extremely valuable app.

I just have two suggestions...

1) For checking on family, you need more than just a phone #. It should notify any device attached to the family members (i.e., iPad, computer, etc) even if that device has no phone #. So if someones phone is lost or damaged in an emergency, they could still respond that they are safe via their iPad, etc.

This could be accomplished by linking devices through not just phone #s, but also via email addresses, iCloud, FaceTime, or even partnering with 3rd party apps like Skype, Facebook Messenger, or Twitter.

2) The alerts should have the ability to set a different radius for each type of alert, rather than all alerts for a location having the same radius.

Other than that, its very good.
