Overview
You need at least 4 days of data to get your first score
The Stability Score is a daily snapshot of your body’s signals
It's a stability score, not a wellness score – it shows how balanced your signals are, not how well you are expected to feel
Use the Stability Score to guide your pacing
Stability not wellness
Your Stability Score is a 'Stability' score, not a 'Wellness' score. It’s a data-based snapshot, not a direct measure of how you feel.
The Stability Score reflects how stable your body's signals are:
Higher score (4–5): Your body is showing consistent, balanced signals, a likely sign of stability. This reflects your signals, not necessarily how well you'll feel.
Lower score (1–3): Your body may be under more stress or strain, with less stable patterns. This means your signals are out of balance, not that you're doing badly. When your score is low, it may help to prioritize rest where you can.
Use the Stability Score to help you listen to your body
The Stability Score is a tool to help you make informed decisions about your daily activities, pacing, and rest, not to give advice about your condition. Let your score guide your pacing, help you listen to your body, and make more confident decisions about rest and activity.
You need at least 4 days of data to get your first score
Stability works by comparing your body’s signals today with what normal looks like for you. So you’ll get your first score after 4 consistent days of Morning Check-ins. As time goes on, and Visible gets to know what average really looks like for you, your scores will become even more accurate.
Choose how to check in and get your Stability Score
Completing your Morning Check-in at a consistent time and place makes it easier for Visible to calculate what normal looks like for you and spot changes in your body's biometrics.
There are two ways to complete your Morning Check-in – using overnight data or morning readings.
Getting your Stability Score from overnight data is available for members with a Visible Band 2.0. Simply wear your band to bed. When you rate your sleep in the morning, Visible will use your overnight heart rate and heart rate variability (HRV) to calculate your Stability Score.
If you don't have a Visible Band 2.0, you will get your Stability Score by taking a short morning reading. Morning readings are available to you if you:
Have a Visible Band 2.0 but prefer not to wear your band to bed. Go to Profile → Stability in the app to switch from overnight to morning readings.
Have a Polar Verity Sense band.
Don't have a band. You'll take a morning reading using your smartphone camera.
If you forget to wear your band to bed
If you choose to get your Stability Score from overnight readings and forget to wear your band to bed, you will not receive a Stability Score that day. There is no option to take a morning reading instead.
If you're only able to wear your band on certain nights, or think you may often forget to wear it, we recommend using morning readings to get your Stability Score.
This is because your average is built on the data gathered either overnight, or in the morning. It’s not possible to accurately switch between the two.
If you miss your Evening Check-in
You will still get a Stability Score if you skipped the previous day's Evening Check-in. Your score will be calculated using the other three factors: resting heart rate, heart rate variability, and sleep quality.
