Heartrate tracking techniques

A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed by one or more processors of a wearable computing device, cause the wearable computing device to perform operations comprising:

• detecting, by the wearable computing device, a first user input to open an application of the wearable computing device;
• detecting, by the wearable computing device, a beginning of an activity within the application session of an application of the wearable computing device;
• configuring, by the wearable computing device, a heartrate sensor of the wearable computing device to operate in a first operating mode based at least in part on the application;
• collecting, by the wearable computing device, first heartrate metrics using the heartrate sensor in the first operating mode;
• detecting, by the wearable computing device, a conclusion of the activity within the application session of the application;
• and
• in accordance with detecting the conclusion of the activity within the application session:
• presenting, by the wearable computing device and via a user interface, heartrate information corresponding to the first heartrate metrics;
• and
• collecting, by the wearable computing device, second heartrate metrics using the heartrate sensor in a second operating mode.

A wearable device, comprising:

• one or more non-transitory memories configured to store computer-executable instructions;
• a heartrate sensor configured to sense biometric data of a user;
• and
• one or more processors in communication with the one or more non-transitory memories and the heartrate sensor, the one or more processors configured to execute the computer-executable instructions to at least:
• detect a first user input to open an application of the wearable device;
• detect a beginning of an activity within an application session of the application of the wearable device;
• configure the heartrate sensor to operate in a first operating mode based at least in part on the application;
• collect first heartrate metrics using the heartrate sensor in the first operating mode;
• detect a conclusion of the activity within the application session of the application;
• and
• in accordance with detecting the conclusion of the activity within the application session:
• present, via a user interface, heartrate information corresponding to the first heartrate metrics;
• and
• collect second heartrate metrics using the heartrate sensor in a second operating mode.
