here is a lap timer (freeware)
There isn't a lot else out there specifically for RC. I use SpreadCE (Excel Clone - http://www.byedesign.freeserve.co.uk/
) to create my own RC utilities such as Roll-out Calc, set-up sheets, etc. It is an excellent spreadsheet with lots of functions. Much better then Pocket Excel. Also - the demo doesn't expire or loose functionality, you just get an "unregistered" pop-up when starting and loading sheets.
