You could do it manually, just open Notepad and write something like:
5:00 - 2000 exp
6:00 - 5235 exp
7:00 - 8420 exp

Granted, that's not an automated program, but it would give you a general idea.

of course u can do it without a tool. So u can do math without a calculator. But its less time consuming and more accurate using the correct tool.

Its also a bad choice to grind 1h just to notice u are way slower, then somewhere else.

I also noticed that people like high values, without ever thinking about the risk of dying or that faster kills with lower exp may result in more exp.

But until i don't see much interest is the exp-o-meter, but it looks like u guys love to whine about the exp in flyff. And i cant understand it, after all the grind in flyff is easier then in fiesta, if u use the correct strategy.
