As the name implies this is a bilirubin tool. A calculator which intelligibly computes the risks at a given bilirubin level and baby age. Not only that but it also stratifies the risks into low, medium, and high with explanations, this is certainly useful and obviates the need for looking at NICU board mounted nomograms!
Honestly, though, I was using the freely available AAP risk nomogram (have a look here), I just downloaded the jpg picture to my PDA and opened it whenever I need (see picture below). However Bilitool clearly replaced the trick and is much more useful and easier to use.
