TailTwin is a mobile app that connects to a microchip embedded in your pet's ear or a collar to monitor its health, mood, and behavior. The app creates a digital twin of your pet, tracking key health metrics such as temperature, movement, hydration, heart rate, and sleep patterns. The app also checks for potential signs of injuries and illnesses. With this data, the app creates an interactive model of your pet, providing insights, alerts, and care recommendations.
