I just released a new iPhone SEO app and Android SEO app called SEMTab SEO Pro. The basic idea is to keep a list of domains saved, and check SEO/SEM stats like Google PageRank (PR), backlinks, Alexa rank, etc. and Social share information from Twitter, Facebook, and Delicious. more

The first two pictures are of the iPhone app, and the last one is of the Android app. SEMTab SEO Pro was built with  Titanium using all native cross-platform UI controls, so it builds both the iPhone and Android app from a single codebase and a single development effort.

The nice thing about SEMTab is that it makes extensive use of Titanium’s event system to fire off simultaneous asynchronous HTTP requests to the various web services and APIs to fetch data about the current domain you are checking. This prevents the application from locking up while fetching rank or share information, and it prevents the HTTP requests from stacking up in a queue and waiting for the ones in front of it to finish. The end result is a pretty slick & simple SEO app that gets the results you want quickly, without feeling sluggish or unresponsive.

Check out SEMTab SEO Pro in the App Store or the Android Market when you get the chance — and don’t forget to leave some feedback with a rating.
