Annet uses it to track when she starts feeding her baby and stuff. But you can us it for tracking all kinds of events, the buttons (including their color) are configurable.
The log shows a list of events and their times.
Adding a note, changing the time and deleting is possible.
How to edit an event?: Do a long click (press and hold it) on an event in the list to change or delete an event.
I hope you find it usefull, let me know what you think!
