What Is the Activity Score?
The Sahha Activity Score is a daily health score that represents how physically active a user is.
It combines movement, activity intensity, and consistency throughout the day into a single score, making it easier for apps to understand a user’s overall activity behaviour.
The Activity Score transforms raw activity data from smartphones and wearables into an actionable signal that supports personalised fitness and lifestyle experiences.
Why Is the Activity Score Important?
Regular physical activity plays a key role in supporting cardiovascular health, metabolic function, mental wellbeing, and long-term health outcomes.
The Activity Score helps surface daily activity patterns that may not be obvious from raw data alone. By summarising activity behaviour into a single score, apps can more easily identify when users are underactive, consistently active, or highly active, and respond with appropriate recommendations.
How to Interpret the Activity Score
The Activity Score is presented on a scale from 0 to 100.
Higher scores generally indicate higher levels of daily movement, activity intensity, and consistency, while lower scores suggest limited movement, long sedentary periods, or inconsistent activity.
Interpreting the score over time, rather than on a single day, helps identify activity trends and behavioural patterns.
Factors Contributing to the Activity Score
The Activity Score is influenced by multiple activity-related factors, including:
- Total daily movement, such as steps or distance
- Active hours and activity duration
- Active calories burned
- Time spent in moderate to vigorous activity
- Extended inactivity or sedentary periods
- Vertical movement, such as floors climbed, when available
These factors are combined to reflect overall daily activity behaviour rather than any single metric.
What Data Is Used From Phones and Wearables?
The Activity Score adapts based on the data available from connected devices.
Smartphones typically contribute basic movement data such as steps, movement duration, and active time. Wearable devices can provide additional signals such as activity intensity, calorie burn, and more precise movement tracking.
Sahha’s scoring model normalises these inputs to ensure consistent scoring across different devices and data sources.
How to Improve the Activity Score
The Activity Score improves when daily movement increases, sedentary time decreases, and activity intensity becomes more consistent.
Common ways to improve the Activity Score include:
- Increasing daily steps by walking more throughout the day
- Breaking up long periods of sitting with short movement breaks
- Adding moderate to vigorous activities such as brisk walking, running, cycling, or workouts
- Spreading movement across the day rather than concentrating it in a single session
- Using stairs or incorporating vertical movement when possible
Small, consistent behaviour changes often lead to meaningful improvements in the Activity Score over time.
