This app gives you a snapshot of the US economy (and snapshots for each state as well). It works great on Android phones as well as tablets.
The iPhone version of this app was featured in Wiley Publishing's book on Incredible iPhone apps and (for weeks) the app was ranked #1 on Apple's top charts for the Finance category.
The app gives you the latest values of key economic indicators (Unemployment, GDP, Housing, Inflation, M2 Money Stock, S&P 500 etc). Its graphs track USA economic data across Democratic and Republican presidencies, across recessions and across many different time ranges.
