I wrote this app back back where there was a single Android phone (as in one, and only one, the G1, like 2008). I might have updated something for the N1, but otherwise I don't think it's been updated since. I recommend against installing this app; it has likely decayed to the point of unusable.
EvenTrend is for tracking events or data over time, such as weight, gas used, hours worked - you define the categories and values. Great for bio-trending, life-trending, or the Hacker's Diet. Built-in graphing, exportable data. v1.0.16: more forgiving swipe, file import buttons
