Activity
Daily movement, steps, active minutes, and workout frequency.
Everything that defines a user, in one profile
A user profile combines demographics with seven days of wearable data in five domains, each with a 0–100 score, a level, and a trend, delivered to your backend via webhook.
How it works
A complete user profile in three steps
Instead of working with dozens of disconnected metrics, teams receive a profile organized into five health domains. They understand who each user is and can design experiences that respond to their reality.
Your app requests a profile
The application requests a user's profile whenever it needs one.
ROOK analyzes seven days
ROOK reviews the synced data from the last seven days and builds the profile.
Your backend receives it
The complete profile reaches the backend via webhook, ready to use.
Five domains, one complete view
Five health domains, each with a score and a trend
Each domain includes aggregated metrics, a 0–100 score, a health level, and a trend. Together they form an overall score that summarizes the user's status.
Sleep
Sleep duration, efficiency, and consistency.
Cardio
Heart rate and heart rate variability (HRV).
Recovery
Recovery, readiness, and sleep debt.
Body
Body measurements and composition.
More than metrics
Levels, trends, and observations per profile
Each profile turns scores into five readable levels, compares every domain with the previous profile, and shows how complete the data behind it is.
Easy-to-read levels
Every score is classified into five levels, from Optimal to Critical, so any team can understand a user's status without interpreting numbers.
Trends over time
Each profile shows whether a domain is improving, stable, or declining compared with the previous one.
Personalized observations
The profile detects positive patterns, trends, and relationships between domains, and turns them into concrete observations.
Honest data
Missing data is never treated as a poor result. Each profile shows how complete the information behind every score is.

Programs that adapt to who each user is
Digital health, fitness, insurance, and engagement teams use each profile to onboard, plan, segment, and message their users.
01Digital Health
Onboarding and follow-up with context from the first interaction.
02Fitness & Wellness
Plans that adapt to where each user has the most room to improve.
03Insurance
Wellness programs segmented by each policyholder's profile.
04Personalized engagement
Messages that follow each profile's trends, not a fixed calendar.

Frequently asked questions about User Profiles
What a user profile contains, how it is generated, and how missing data is handled.
What is ROOK Scores User Profiles?
User Profiles transforms wearable data already synchronized with ROOK into a structured user profile. It summarizes recent information to provide a consolidated view of activity, sleep, cardio, recovery, and body health.
What information does a user profile include?
Depending on available data, a user profile may include aggregated metrics, scores from 0 to 100, health levels, trends, coverage or confidence indicators, personalized observations, an overall score, and available demographic data.
How is a user profile different from daily health data?
Daily data shows events and summaries for a specific date. A user profile primarily analyzes the previous seven days and organizes information across five areas. Some recovery calculations may use up to 14 days of sleep data.
How do I know when a profile has changed?
User Profiles do not update automatically. When new data is synchronized, your application must request a new profile and compare the result with the previous version.
What happens when data is missing?
A missing metric is not treated as a negative result. ROOK uses other available data when possible and reflects reduced coverage through confidence indicators. If there is not enough information, some fields may be returned as null.
How is a user profile generated and delivered?
Your application requests the profile through the API, ROOK processes the synchronized data, and the result is delivered asynchronously to the configured Data Webhook.
