You know how you have a first date with someone and you just don't know how it's going to go, so you call your girlfriend and tell her to call you at exactly 7pm (right in between drinks and dinner) so you can bail if you need to? The app Excuse Me is ideal for this situation. Set the timer and a fake call will come in to "excuse you" from your situation.
Now, in the free version the voice is annoying and not in English, but you still have an excuse that was on time and free (not complaining here!). In the paid version (still only $1.99) the app allows you to designate who the fake call is coming from, so you really can make your white lie look real when you tell your date that you need to bounce because your girlfriend got locked out of her house. (Other similar apps are Fake Caller or Fake-a-Call - they all get the job done when you're in a pinch.)
I do think that phones, technology, online dating and apps are making our world just too damn complicated, but we need to jump in head first, right?
