I've developed some poker web based tools that I'm giving for free to anyone who wants to add them to their website.

It's an all-in equity calculator and an ICM equity calculator, you can try them here: Holy Grail of Poker - Tools

Here is a screenshot of the all-in equity calculator:


To add them to your website simply add these three lines of code:
Code:
<iframe src="http://holygrailofpoker.appspot.com/iframe.html" width="100%" height="650px">
<a href="http://www.holygrailofpoker.com/">Holy Grail of Poker</a>
</iframe>
If you don't want both, you can hide one or the other by adding "?hide=icm" or "?hide=equity" after iframe.html
