Use streams and properties to configure the tracking you want.
Start by creating a Stream and giving it a name. This will collect the different entries you make over time.
Next begin adding properties to the stream by selecting from the list and configuring the related options. Start with a simple number and then related text or a money value.
Select from date, time, numbers, money and text to configure the stream that works best.
Select from additional options to make entering data easier, like using a start and stop value to prevent having to calculate the difference yourself.
Also choose from ongoing math helpers like a running total, overall total or calculate the difference between the previous entry.
Example use cases include counting trips to the gym, tracking hours on a boat or seeing just how often you go out for dinner.
