Is Halo Lytt a medical device?

No. Halo Lytt's metrics are for wellbeing awareness. They are not clinically validated, and the device should not be used to diagnose, treat or monitor any medical condition.

This distinction matters. Consumer wearables estimate physiological signals from optical sensors and movement. They are useful for spotting patterns over weeks, and they are not diagnostic instruments. A regulated medical device goes through a different approval process entirely.

If you have a specific concern about your child's health, sleep or breathing, speak to a doctor rather than relying on wearable data. The American Academy of Pediatrics publishes parent-facing guidance worth reading alongside any tracker.
