No one likes waiting on hold, but there’s an app to do that for you. LucyPhone can be used as a middleman between your phone and the company you’re calling, and will automatically call you back when a live agent appears on the line. The free app first patches you through to the company after you provide it with your phone number. You then simply press the * key twice to disconnect when on hold. LucyPhone will stay on the line and wait while you continue with your day.
