Computer for lawyers, not an app.

Here is a neat website that allows you to calculate a deadline and due dates.  Not an application, so there’s nothing to install on your computer or iPhone or BB – and for the overhead conscious it’s free.

WolframAlpha.

There’s a free download which will allow you to have a widget in your Vista sidebar, or you can add to your Explorer or Firefox

For those absolutely needing an iPhone app here is an alternate – Law on My Phone.
