Test meter

Excellent tool that could be better.
The readings should be viewable as a graph, each parameter assigned a different color.
Have it so the main data is “moved” to a category and then not on the main screen. As it is now all the data stays there and is also in a category. If you clear the main screen your category data gets deleted.
