Three major companies released updated sleep tracking devices in 2026, and they work differently than older models. Oura, Whoop, and Eight Sleep all added new sensors that track more health signals while you sleep. These devices use artificial intelligence—computer software that learns patterns—to give you better information about your sleep quality.
Sleep trackers have existed for years, but they mostly just counted how long you slept. The newer versions now measure things like how much you move during the night, your body temperature, and even stress levels. Companies spent millions developing artificial intelligence systems that can understand what all these measurements mean for your health.
Regular people who want to improve their sleep are the main users of these devices. Athletes use them to track recovery after workouts, and some people with health problems use them to understand their sleep patterns better. If you wear a smartwatch or fitness tracker now, you probably already have basic sleep tracking, but these specialized devices give much more detailed information.
Over the next few months, these three companies plan to add even more features through software updates. They are also connecting their devices more closely with popular phone apps like Apple Health and Google Fit. By the end of 2026, users will be able to see all their health data in one place on their phones.
