UltraBI is the simpliest BI app available for iPhone/iPad devices. UltraBI displays two types of data, KPI (Key Performance Indicator) data and graphical data. Graphical data can be either line graphs, bar plots, or pie charts. Unlike most mobile BI apps, UltraBI doesn't use expensive proprietary back-end software to provide data for the app. As long as you can create XML data files in the required format and place those files on a web server accessable via the internet you can provide data to the UltraBI app.
