iPhone Giveaway of the Day - TrendLine

TrendLine is a tool to easily enter, manage, display and analyse just about any data in (x,y) pairs. This app does automatically calculate the best-fitted line (a trendline) and displays that line amongst the data. The equation of that line and the statistics of your data are available as well. TrendLine can be used easily by both students and professionals. It is particularly useful for a quick analysis of various types of data. It does support linear regression.

Data can be entered directly via the keyboard into the built-in database, and the data can be plotted and analysed instantly. Plotting is really easy, the axes are autoscaled! And while you are entering the data, a TrendLine is being calculated automatically without any configuration required. Try it for yourself and see how easy data analysis can be!
