1) It appears to be continuously getting GPS data. That will kill my battery. Dead battery = I'm late anyway I may need to uninstall until this is fixed.
2) I don't need to be reminded of everything on every calendar I have access to. Have it so I can select which calendar I need to bounce for.
3) Along the same lines of 2, allow me to ignore specific events. I subscribe to a couple general holiday calendars and I don't need to be told when to leave for "Memorial Day" or whatever.
Otherwise, great concept. I look forward to keeping up with your progress.
