There is really only one thing you need to start registering your Life Curve and that is a pocket planner or any other kind of notebook. Of course you can use the calendar in your PC or in your mobile as well. But still I find the  simple pocket planner the best choice.

In the  figure to the right you see what typical registrations may look like. As mentioned before, the variations from one day to the next are in most cases not that big. Here we can see registrations made during the summer with a slightly raising trend in the yellow zone.
