GREAT app. In case you do decide to put more of your time into it, a suggestion based on the comments above - record the configuration automatically:
- which radios are on (CDMA, GPS, WIFI)
- reception power and type (# bars, 3G/EVDO)
- number and/or which apps running
That's a lot of info, but I believe it could be incorporated easily in the graph. For the radios, you could use different colored blocks piled vertically behind the graph's line. Same for the reception - perhaps use a red block instead of a pink one if on 3G, and just put the number of bars in the block. Number 3 above might be fun for statistics-freaks, but perhaps the hardest to implement and represent?
