Corkboard Connections: Fun Countdown Timers for the Classroom. Not an app, but online timers that may be used on a Smartboard.
I love these! Animated timers that you can put on the projector. Gives students a visual for the time they have remaining. Plus a fun surprise (noise cue) when time is up! :)
