Spire Health Tag Sleep, Stress and Activity Tracker (3-Pack)

Spire Health Tags, along with a companion app on your iPhone, help you easily track and improve your health. Attach Health Tags to the clothing you wear most often (underwear, bras, pyjamas and more), and then forget about them. They're ultra-comfortable, never need charging, are waterproof and are washer/dryer safe.

Built-in clinical-grade sensors track your sleep, stress, activity, heart rate and respiratory patterns, enabling the app to provide a dashboard of your progress, guided exercises and personalised recommendations to help you sleep better, reduce stress and be more active.
