Thea

THEA is a soft fabric wristband for people with allergies. It has no screen: light glowing through the fabric and gentle vibrations show how close you are to an allergic reaction, and how fast you’re getting there, so you can act in time. Tap it to check your status, or hold it to flag a trigger like a dog in the room. If a reaction is near, a calm voice guides you step by step. A phone app logs events and patterns to share with your doctor. Everything is processed on the device, so your data stays private. It’s designed to feel like a bracelet, not a medical device.
