The full story

Everything to know about Bye Bye Button

Give yourself a cue to leave

Bye Bye Button starts with a familiar social problem: you want to end a conversation, but finding the moment feels uncomfortable. Pressing the accessory triggers a call or text on your paired phone, giving you an interruption you can use to step away.

You choose the displayed caller name in the app. The product supplies the interruption; you decide how to respond and what to say.

Your phone is part of the setup

The keyfob needs its paired phone and app to produce the interruption. The company also offers an app-only product, so check which one you are ordering. The physical accessory gives you a separate button to press without first opening the app.

The company says the button works with the app closed and the phone locked. Try your own pairing, notification settings and chosen call or text before taking it to an event. You can see how the interruption appears on your phone while there is still time to adjust the setup.

An interruption, rather than emergency assistance

The button is a social convenience accessory. It does not dispatch help and should not be relied on as an emergency-response or personal-safety device. Its job is to create a reason to leave an awkward conversation.
