SpeakerClock

Big red LED digits allow you to see the timer even at great distance so you are free to move while you give the talk of your life. SpeakerClock emulates the famous countdown clock that all speakers at TED conferences need to adhere to.
Start the clock and place it within your view when giving a public talk to see at a glance how much speaking time you have remaining. The "traffic light" gives you visual feedback when it's time to wrap up or make your closing remarks.
Use it for actual public speeches or train with it for the fateful day when you too get the call to speak on important issues.
"Personally I use SpeakerClock when timing the recording of YouTube videos. This way I never run over the maximum 10 minutes there and the "traffic light" helps me nail my closing arguments every time!"
