Calling friends is hard.

It feels like rejection
What if you can just call a friend when you press a key?
The app would go through a queue that you set up and call each friend in order. Whether the friend answers or not, they're placed into the end of the queue. When you call them their phone does not ring. It just shows a notification for a while. Maybe a minute or 5, and then silently disappears without leaving a record that you called them.
This way you press a key, and just wait for a friend to pick up.
