This small gem does it all. Set speaking time, tap, go. Nicest feature: changing speaking times by swiping.
I usually like to use an old analog pocket watch when I give a talk, but I loved this app from the start. The LED/TED-display is bright and crisp and the numbers easily.

Nice tool for teaching/training session, and also in the home. Only disadavantage I can see: Like all timers it may keep you standing next to where you put it.

But then there is so much more to giving a great talk than getting the time right :)
