The Spire Health Tag is the newest product from Spire. Based on extensive research and customer feedback we have created the world’s smallest consumer device that discreetly adheres to the clothes you wear most and uses advanced algorithms and deep learning to provide personalized, real-time health guidance for sleep, stress, and daily activity through continuously analyzing breath and heart rate inflection points.
The Spire Health Tag app is currently only available on iPhones (iPhone 6 and above, iOS 10 or higher). We plan to provide Health Tag compatibility for Android devices in the near future!
Yes! Health Tags are waterproof and are designed to be able to go through the washer and dryer. When you first apply Health Tags, we recommend waiting 24-hours before washing your clothes to allow the adhesive time to set.
Health Tags are intended to be purchased in packs and attached to the clothes you wear most often such as underwear, pajamas, or activewear. This allows the Tags to track your daily activity including sleep, exercise and stress levels. We’ve found that many people own around 8 pairs of underwear, briefs, or bras that are part of their regular “rotation,” so an 8-pack is a great way to get started. Our smaller 3-pack can be a starting point for people who only want to track a specific type of activity, like sleep (by putting them on pajamas) or exercise (running shorts, swimsuit, etc).
Health Tags are designed to work together as an integrated system. Each pack is associated with an individual user so it’s not possible to split a pack of Health Tags among multiple people.
Health Tags are meant to remain on a dedicated article of clothing. They’re waterproof so they can safely go through the washer and dryer, making it easy to just leave them in place and wear day-after-day. Occasionally you may want to move Health Tags to a new piece of clothing, so each Health Tag pack comes with additional adhesive strips to help you attach the Health Tag to your new clothes.
Yes, Health Tags never need to be recharged but their batteries will eventually run out. When you join Spire+, we’ll replace your Health Tags for free so you never need to be concerned about battery life or maintenance. We try to do our part to be eco-conscious by recycling components from every Health Tag we receive back from you.
