Today Fitbit announced a new set of sleep scoring features for premium users. The Sleep Profile, which launches Wednesday through the Fitbit app, is the latest subscription data that Fitbit Premium members can use to better understand their unique sleep type and identify their strengths and weaknesses.
Using a month’s worth of sleep data from about 60,000 Fitbit users, the company examined 1,000 unique sleep attributes and eventually truncated and compiled them into 10 metrics. Five were already present in the Fitbit app, including sleep stages and duration. But the five new categories assess bedtime consistency, number of days with naps, time before sound sleep, disrupted sleep, and “stability,” which averages the number of brief, usually unnoticeable, awakenings during the night. With these ratings, users can see daily, weekly, and monthly trends in each category and see where they are (and should be) within the data range of other users of the same age and gender.
Each month, users are also assigned sleep chronotypes based on their data. Each of the six species is named after an animal with similar sleeping patterns: giraffe, bear, dolphin, hedgehog, parrot and turtle. According to Fitbit, besides being fun, these sleep pattern identifiers aim to help people remember and reflect how their patterns change over time. Animal-based sleep types aren’t a new concept to sleep science, or even wearables; Samsung introduced a similar feature in the Galaxy Watch 4 this year.
The sleep profile requires users to wear a compatible Fitbit device (Sense, Versa 2 or 3, Charge 5, Luxe, Inspire 2) for at least 14 days in a calendar month to receive ratings. As mentioned, the feature is exclusive to Fitbit Premium subscribers, who pay $10 a month for access to Insights and a mid-range library of fitness and mindfulness content, among other paywall perks.
