MyBefia is a great little site to compare Apple iPhone applications based on their rankings in the App Store. Add up to three applications (the only annoying thing is you have to look up its iTunes Store URL) and see how rank has changed over time. It also shows estimated market share, review rankings over time and popularity. The widgets are embeddable via Gigya.
