Use the patent pending Bye Bye Button to quickly and gracefully exit awkward situations. Bad date? Long winded coworker? Annoying Neighbor? BYE BYE!!!The Bye Bye Button Application wirelessly interacts with the Bye Bye Button device to help you quickly and discreetly generate a fake (yet REAL!) phone call to get you out of undesirable situations. Simply setup the application once, let it run in the background, and when you press the button, you'll get a "real" phone call from anyone you choose in your contact list (We briefly link the real incoming call to your chosen contact, then erase the trace after your getaway). Because we generate real phone calls, you don't have to have the application unlocked, and you don't have to plan ahead. PLEASE NOTE: because we generate real phone calls and text messages that cost money, we will end up adding some kind of paid service in the future. The paid service will likely be along the lines of a monthly service fee, a per use service fee, or possibly some combination therein. Because we generate real calls and texts, you might incur additional costs from your carrier when using these features of this application. Use of this application is subject to our terms and conditions. Say "Hello" to the Bye Bye Button and "BYE BYE" to awkward social situations!
