HBYear

Plot yearly activity - get a quick and simple overview

HBYear plots data collected via classical "horchboxen" in a simple to read graph. The app was developed together with Büro Echolot to plot such data for analysis and reports. The graph is based on CSV files containing timestamped activity data. HBYear runs on OS X10.7 or newer.
