What does my heart score mean? 

Your heart score gives a broad indication of your heart health relative to other individuals of the same age and sex, with a higher score indicating better heart health.  

How is my heart score calculated?

Various inputs, including the biometric data gathered from your profile and the heart rate data collected via your device, are used to project a range of clinically-relevant aspects of your heart’s performance. When measures from a wide enough range of states (such as exercise, sleep, and day-to-day activities) are available, these heart health aspects are combined to give a single heart score. You need to collect and upload at least seven (not necessarily consecutive) days’ worth of valid heart rate data before you can see your heart score. 

I don’t see my heart score, even though my other scores (activity, fitness, and sleep) are available

Your heart score requires significantly more data than the other scores to be calculated. Therefore, it is possible for the amount of data you have gathered and uploaded to be insufficient for a heart score to be made available. We recommend wearing your device as frequently as possible—especially during sleep—and uploading data as frequently as possible. 

My heart score is lower than I thought it would be 

It is important to remember your heart score is a relative, and not an absolute, measure of your overall heart health. Your heart score is a stable, longterm, view of your heart health and continues to be more accurate with the more data that is collected. Please refer to the Interpretation of LifeQ Scores section of this document for further information on how the scores are distributed. 

How can I improve my heart score?

Your heart score can be improved gradually by exercising regularly, getting enough sleep, and making sure your profile is kept up to date. It’s important to always consult your physician when planning drastic fitness and health interventions.

My minimum and maximum heart rate values are not displayed in the app 

Our filters will discard data that is deemed as low quality. Loss of data during the day can impact daily values, like the minimum and maximum heart rates. Furthermore, resetting your device may lead to the loss of data. To avoid this happening, ensure your device is worn throughout the day, and is also worn correctly—not so loose that it moves around on your wrist too much and not so tight that it restricts blood flow. 

What is my resting heart rate and how does it differ from my minimum heart rate?

Your resting heart rate is calculated using a range of data points, spanning a range of different times and circumstances during a day, with the intention of indicating your heart rate under resting but wakeful conditions. In contrast, your minimum heart rate is just a once-off measurement of your lowest heart rate, intended—together with your maximum and resting heart rate—to indicate the total range of your heart rate over a given time period.  

Why does my resting heart rate vary so much from day to day?

Various factors can affect your daily heart rate, such as fatigue, stress, activity levels, nutrition, drinking alcohol or acute illness. Your resting heart rate is a reflection of your heart rate under resting but wakeful conditions for a day, which could differ significantly from day to day. 

Why can’t I see my resting heart rate? 

While other values, like your min and max heart rates, are visible in the app directly after uploading your data, your resting heart rate is a single value based on data collected throughout the day, including making use of sufficient data during wake hours. For this reason, the resting heart rate value is only shown a day after your daily heart rate values have been uploaded and analysed. 

The real-time heart rate on my device is incorrect

Please ensure your device is worn correctly. Ideally, it should be placed two fingerbreadths above your wrist bone and fit snugly but not so tight that it restricts blood flow. Please also ensure that there is no interference, such as excessive moisture, ambient light or clothing, between the green light of your device and your skin.   

Can the heart information displayed in the app tell me if I have a cardiovascular disorder?

The app cannot be used to diagnose cardiovascular disorders or to classify individuals as ill. We recommend that you seek professional advice if you are concerned about your heart health.


User reports missing heart score 


  • Does a profile exist for the user?

  • Is the user’s device connected to their profile?

  • Was the user’s profile created less than a week ago?

    • If the user’s profile was created less than a week ago, they won’t have enough data to compile a score with yet, and will have to keep wearing their device until at least seven days’ worth of data has been collected. Due to this requirement, users should expect to see a score on the eighth day of data collection.

        • PLEASE NOTE: Do not share this seven-day cut-off with external users. Due to the intricacies involved in calculating the heart score, a result is not guaranteed, even after seven days’ data has been collected.

      • Does the user have enough data collected? 

        • The user needs to collect and upload at least seven days’ worth of data before they can see their heart score. Advise them to keep wearing their device and upload data regularly.

    • User reports missing or perceived inaccurate minimum/maximum heart rate 


      • Were the readings the user suspects were the true minimum/maximum heart rate output for longer than 15 minutes?

        • To ensure the values are accurate and a true reflection of the user’s minimum/maximum heart rate, only values that are logged for 15 minutes are considered. 

      • Did the user reset their device?

        • If the device was reset within the 15-minute period before the minimum/maximum heart rate in question was observed, the data won’t be displayed in the app.

    • User queries whether they might have a cardiovascular disorder, based on their heart data

      • The app cannot be used to diagnose cardiovascular disorders or to classify users as ill. Advise the user to seek professional advice if they are concerned about their heart health.
