edit i misread your question - the app below does not show the name of the task in the timer pop-up
I'm running it under linux; there are windows and mac versions too. Definitely my favourite way to do it since I'm studying from textbooks which I have torrented, muahahahah. I'm already at my computer so I may as well use an application that keeps statistics for me.
FYI there is this application as well: http://www.pomodoroapp.com/
You can install it and use it to write down things you want to do etc. and how many pomodoro repetitions you want to do and things like that.
The one I made is windows only, but here's one for linux: http://www.pomodoroapp.com/pomodoro-timer-for-linux-ubuntu/
Enjoy! Stay disciplined. Work on only one thing for your 25 minutes - there's almost nothing that can't wait 25 minutes, and you get a break in 25 anyway. It works really well :)
Oh and write down everything you need to do on notepad, so you can easily pick a goal and cross it off. Makes is so much easier. (Wait, the linux version kind of does this for you .. I dunno, pick what works :) )
