Came across Mybefia.com this evening, and I have to admit it is pretty cool. The site allows you to compare app rankings from within the App Store, Alexa style. You can add up to 3 apps at the top of the site, and view the app’s rank for the current week. You can also view popularity, reviews and estimated market share metrics by clicking on the ‘previous’ and ‘next’ links.
A cool tool indeed. The only part that can be a bit of the hassle is you have to first find the App in the iTunes Store, copy the iTunes Store URL and then paste it into Mybefia. No biggie though.
