Measurement
Record a number each time, compare it with a target, and watch the trend.
Turn on the section
Turn on Measurement in Sections of a task or template. Steps don't have it.
Set up items
Add items with + on the section header and set Name, Unit, Target and Reached when. You can have several — say, weight (kg) and body fat (%). Set them on a template, and every task and routine run made from it starts with the same items.
Enter values
In a task's Measurement section, tap an item to open it. Enter the Current there, and change its name and target if you need to. Templates have no current value.
When you first reach the target
The first time a value you enter on a task reaches its target, a card pops up and it counts once toward an achievement. Only items with Reached when set count. Tasks made from the same template share it — reaching the target again on a later run doesn't pop up again. Change the target or Reached when and it counts as a new target. On a project template, once one person reaches it, it counts as reached for everyone.
View the trend
Open an item and tap the line-chart button at the top center to see its trend — the last 10 tasks made from the same template that have a value (finished or not), filling ten slots from the left, earliest created first. It works on templates and on tasks made from a template. Items join up by matching name and unit, so changing either starts a new line.
Send changes back to the template
If you added or removed an item on a task, or changed its name, unit, target or Reached when, you can apply that change to the template in Template Improvement. The current value belongs to that task, so it is not carried over.
