Angel Sensor™ is a light and unobtrusive wristband that can be worn 24/7. It tracks the body's vital signs and physical activity, and continuously communicates this information to smart phones and other digital devices.
Angel Sensor is designed to make health tracking hardware as accessible as USB drives. We offer a high-quality sensor as a building block for new digital health products by both enterprises and startups.
Angel uses proprietary sensor technology to continuously monitor heart rate, skin temperature, and blood oxygen saturation, while also tracking physical activities such as walking, running, or sleeping. Angel ships with open-source SDK and a sample app to help expedite development.
