Title: utimer 0.4

Via the Launchpad page:

µTimer ("utimer", pronounced "micro-timer") is a multifunction timer (command-line only). It provides a timer (e.g. count from 0 to 4 minutes), a countdown (e.g. count from 10 minutes to 0), and a stopwatch.

I find it mainly useful for the stopwatch feature.
