Simple Android app for logging your energy level throughout the day.
After installing (and restarting the phone), a screen will come up every hour asking what your energy level is.
You can then view a graph of your daily energy level or of your average energy level per hour.
There a bunch of me-specific hacks in the code you might want to remove like the fact that I discard data between 1am - 8am (I'm rarely awake then so the data is mostly noise).
Project is set up to be built with IntelliJ.
Uses jjoe64's GraphView library for graphing.
