Do you have a low resting heart rate (RHR) that has been given an amber or red rating? Are you still waiting for your VO2 max score? Or maybe you previously had a rating displayed and now it's gone into hiding? We can understand if you're starting to wonder if something has gone slightly amiss, but let us assure you that we have your best interests at heart (pardon the pun!)  


For the cardio-enthusiasts amongst us, a low RHR often reflects highly efficient heart functioning. For example, athletes often have a healthy lower-than-average resting heart rate (it’s been reported that Roger Federer has a RHR of 35bpm).

 Conversely, for inactive individuals, the same low RHR could be indicative of the heart condition bradycardia and may require medical attention.

Our team of data scientists are hard at work to develop an analysis model that can identify when a low RHR is due to athleticism and alternatively when it could be indicative of bradycardia.

 We aim to have this feature available in the app as soon as possible.  In the meantime, we believe it’s best to err on the side of caution: we'll issue you an amber or red RHR rating and hold off from generating your VO2 max.

If you’re concerned about your low RHR we recommend a visit to your doctor to learn more about what this means for you. 


 If you have an average RHR above 57bpm displayed within the app but don't have your VO2 max rating yet, please send a screenshot of your Heart dashboard to our support team
 and we'll look into it for you.  

Note: Scientists avoid calculating Vo2 max for anyone over 65 years of age! Our analysis models are based on current scientific practice, which is why if you're 65 years or older, we won't generate a Vo2 max rating for you either!

 Eventually, we hope to develop an algorithm that caters for all age groups, but in the meantime we simply have to err on the side of caution and hold off from rating your Vo2.
