Today Fitbit announced a set of new sleep assessment features for premium users. Launched through the Fitbit app on Wednesday, Sleep Profile is the latest subscription-only insight 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 roughly 60,000 Fitbit users, the company studied 1,000 unique sleep attributes, eventually chopping them up and compiling them into 10 metrics. Five already existed within the Fitbit app, including sleep stages and duration. But the five new categories assess bedtime consistency, number of napping days, time before deep sleep, interrupted sleep, and “stability,” which averages the number of brief and usually inconspicuous awakenings during the night. . With these assessments, 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 will also be assigned sleep timelines based on their data. Each of the six types is named after an animal with similar sleep patterns: giraffe, bear, dolphin, hedgehog, parrot, and turtle. According to Fitbit, in addition to being fun, these sleep pattern trackers are meant to help people remember and reflect how their patterns change over time. Animal-based sleep types are not a new concept to sleep science or even to wearable devices; Samsung introduced a similar feature on the Galaxy Watch 4 this year.
Sleep Profile requires users to use 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 assessments. As mentioned, the feature is exclusive to Fitbit Premium subscribers who pay $10 per month to access insights and a moderately sized library of fitness and mindfulness content, among other paid perks.
