Workout vs. All Day Activity

The Under Armour Connected Fitness platform provides two main ways to store data about when a user is active: Workout and All Day Activity. They have some key differences, which are important to understand.


A Workout is a deliberate physical activity that the user explicitly starts and stops.

The user’s taking of explicit action with regard to recording a Workout signals that this stretch of time is important to them, so a Workout records data at a much higher time granularity and records more types of data (like heart rate, power, route, etc.).

While a user is doing a Workout, the data is stored locally on the device taking the measurements, or in your application. The data is stored to the UACF platform at the end of the session.

Example devices that you might collect data from for a Workout:

  • A GPS running watch
  • A heart rate monitor
  • A cadence sensor

All Day Activity

An All Day Activity is a continuous activity that lasts all day.

This is data that’s collected passively about the user without their explicitly starting or stopping it. Because this data is likely less important to the user, the time granularity of the data is lower and the type of data captured is more limited.

All Day Activity data is stored every 15 minutes throughout the day. A specific device is used as the source of All Day Activity.

Example devices that you might collect data from for an All Day Activity:

  • An activity tracker

What About “Time Series”?

The phrase “time series” is a bit like the word “data” in that it can easily be over-used so that it becomes almost meaningless. Strictly speaking, both Workouts and All Day Activity record time series data (at different granularity): They contain buckets of data that represent a discrete slice of time and those slices are ordered. But because of it’s generalness as a term, we try to avoid using it unless it’s the name of something and prefer some more specific term.
