The app to gauge how much someone wants you to fuck off.
Who said that anger couldn't be fun?
Fuckumeter lets you see how annoyed someone is with you and adjust how annoyed you are with them, right from a widget on your home screen. It is thought for couples, throuples, besties, friend groups, families—any combination of humans with smartphones. It requires no registration, works by invitation, and supports multiple devices, relationships (and groups!).
It's like a social weather map.
Currently in development for Android, but who knows what the future holds.
