Why is the icon a bear paw?

Sarah is a bear who was rescued by Camille, the app's developer. She gave her name to Saracroche, and her paw gave the logo.

The joke that goes with the name: you ask "Do you know Sarah?", the other person answers "Sarah who?", and you reply "Sarah Croche!", which sounds exactly like "it hangs up" — what the app does to every unwanted call.

Thank you, Sarah.
