Yes, SmartGo Kifu is designed specifically for the iPad, while SmartGo Pro is for the iPhone and iPod touch. They share much of the same code, but SmartGo Kifu has more pro games (33000 vs 22000), the ability to set up positions and mark points, and much better book view.
When I originally created SmartGo Kifu, I expected Kifu and Pro to diverge more than they have so far. It's possible that I might be able to turn SmartGo Kifu into a universal app at some point.
