Looking for a “rising number” widget

I’m trying to find a widget that will display a rising number amount.

I need to start at a specific number and then have that number ticking over by XX amount each day.

For example: Garbage dumped to date: 270,300 tons
And every day it goes up by 1200 tons
I want the widget to display a constantly increasing number – increasing by 1200 every days

But I’ve had ni luck – perhaps because all the likely search terms come up with something else: countdown, timer, maths, number, count etc

Does anyone know of such a widget ?

thanks
