1. The cat page#
The cat in read mode. Weight stands among the fields with its latest value and a small course under it.
2. Turn on editing#
The pen in the bar turns on editing; every field gets a pen of its own.
3. Enter the weight#
The editor takes the number in the unit your device prefers, the date it counts from, and the private mark. Save.
4. The graph#
The clock on the field opens its history; a number's history is a graph: the measured points, the smoothed line, the trend, over the range you pick.
