We've taken the very popular Pathway Central and turned it into an iPhone/iPod Touch web app that you can use on the go.  It features all 100 pathways on the site, along with the complete descriptions and related products.

Since this is a web app, not a native iPhone app, it's free and 3 simple steps to bookmark the web app:.

1. Go to www.sabiosciences.com with your iPhone or iPod Touch.
2.  Tap the red header that appears on top
3.  Tap "+" at the bottom to add icon and bookmark for easy access.
