Apple has been granted a patent (number 10,104,219) for tracking activity data between a wearable device (the Apple Watch) or two (another Apple Watch) paired with a companion device (the iPhone). Hey, the company really wants you to own multiple smartwatches of its making.
An Apple Watch can gather health data through one or more sensors, and then transmit this health data to iPhone or, per the patent, an iPad or even a Mac. This health data can provide information that relates to a streak of a physical activity such as a streak of several consecutive days in which a user, who has worn the accessory, has moved (e.g. walked) more than a predetermined distance (e.g. over one mile) each day.
The accessory can keep track of such a streak while the user wears the accessory over a period of time. However, Apple wants to make it easy for this set-up to work with multiple smartwatches.
Here’s the summary of the invention: “A set of wearable devices, each paired with a companion device, are configured to cumulatively maintain data about physical activities even though a user may switch between wearing them over a period of time. For example, a streak of workouts over many days can be maintained while the user switches between two watches over that period of time.”
