boAt is an Indian consumer electronics brand known for affordable audio products and wearables. Its range includes smartwatches, fitness bands and a smart ring worn on the wrist or finger. The devices combine notifications and calling features with everyday activity, sleep and health tracking.

How it works
Lights beneath the device measure changes in blood flow to estimate heart rate and blood oxygen. Motion sensors track steps, movement and sleep, while software groups activity into workouts and broader wellness measures. Depending on the model, results appear in the boAt Wearables or Crest app as readings, trends, exercise records and reminders.

Key considerations
The range is broad, and sensors, apps and metrics differ between models. A feature shown on one boAt watch may be missing from another.
