Another raaza app in the wild. This one is US Flu Fighter, which is basically a mashup of various different CDC feeds with Facebook and Twitter in an iOS native app. It’s another one with a Ruby on Rails web services back end, which I’m finding increasingly handy for quickly building such back ends. I used the CorePlot framework to draw the graphs, which was a pleasure to use once i got familiar with it. US Flu Fighter has been submitted to the CDC’s Flu App Challenge so please go ahead and give it a vote.
