NORA smart sock is not an FDA approved service or medical service. This APP does NOT claim or imply to provide any service for "diagnosing or treating". This product is only intended to assist you in tracking your baby’s general well-being and is NOT intended to replace you as a caregiver. Do NOT use the Smart Sock as a diagnostic tool. Do NOT use the Smart Sock if your doctor recommends otherwise. The temperature sensor built-in the product is NOT a body thermometer or FDA approved clinical thermometer. The position of the temperature sensor (on feet) does NOT allow it to measure the body’s core temperature or indicate any illness. The temperature sensor mainly detects the effect of ambient (room) temperature change for the general comfort purpose.
