Some conversations end naturally. Others require intervention. The patent-pending Bye Bye Button™ gives you a fast, graceful escape from bad dates, long-winded coworkers, surprise neighbor encounters, and anyone who says, “One more thing…” for the fourth time. Press the button and your phone rings. That’s it. The Bye Bye Button app connects wirelessly to your Bye Bye Button device and generates a real incoming phone call when you need an excuse to escape. No fumbling with your phone. No unlocking the app. No setting a timer. No planning your social emergency in advance. Someone cornered you at Costco? BYE BYE. Bad date entering hour three? BYE BYE. Coworker beginning a story that clearly has a prequel? BYE BYE. Because the system generates real phone calls, it works even when your phone is locked and the app isn’t open. Press the button, get the call, and leave through the front door like an adult. Please note: Bye Bye Button uses real phone calls and text messages. Depending on your mobile plan, carrier charges may apply. Use of the app is subject to our Terms and Conditions. Say HELLO to the Bye Bye Button™. And BYE BYE to conversations that should have ended 20 minutes ago.
