So today I've pushed out several changes to androidstats.com that support this way of looking for popular apps and the results are looking good. The front page now contains the top 5 applications and top 5 games that are moving the fastest up the charts. We also show the top 5 apps and games that are dropping down the charts. The end result is a much better look at movement within the Android market place.
We've made several other changes including displaying the app's description, category and movement (from last week and the previous day). The movements are updated daily, so come back and check often.
