We’ve updated the Stability Score to give you a more accurate daily snapshot of how your body is doing. The improved algorithm is better at detecting meaningful changes in your body’s signals, while the redesigned Stability page makes it easier to explore your recent heart rate, HRV, sleep and symptom data. Together, these updates give you more useful insights to help guide how you pace your day.

Your Stability Score gives you a daily snapshot of how your body is doing, helping you decide how to pace your day. Now, we’ve made some adjustments to make it more accurate.

We’ve improved how your score responds to smaller changes in your body’s signals, and redesigned the Stability page to give you more context at a glance.

Better insight for your day

Your Stability Score brings together your resting heart rate and heart rate variability (HRV) plus your self reported ratings for sleep and symptoms. It gives you a score from 1 to 5 showing how steady your signals are.

The updated algorithm is better at picking up meaningful changes in your body’s signals, without being disproportionately affected by smaller fluctuations. These new scores should be more accurate in terms of how recovered or resilient your body is, giving you more useful insight to guide how you pace your day.

Your score might look different at first

With this update, you may notice some differences in your scores. For example, a day that previously gave you a 4, might now give you a 3. These differences may take a little bit of time to get used to, but you should find that the score is a more accurate aid for pacing. As always, use your Stability Score alongside how you feel and what you know about your body.

Your recent signals at a glance

The redesigned Stability Score page gives you a view of how your signals have been changing recently.

Tap the resting heart rate, HRV, sleep or symptoms cards to expand them and see your data from the past seven days. These charts show your data from the past seven days, alongside your normal range.

Your normal range is based on up to 90 days of your previous data. Your score compares today’s signals with this range to calculate your score.

If you’re newer to Visible, it uses the data you have so far and gets to know what’s normal for you over time. The more you use Visible, the more accurate it becomes.
