An energy score from 0 to 100%, from Apple Health.
An energy score is one number that estimates how much you have left today. Lumi Moods works it out from what you share from Apple Health, such as recent sleep, HRV and resting heart rate, and compares that with your own usual levels.
Lumi Moods is not released yet. It is coming soon to the App Store, so nothing on this page can be tried today.
How Lumi Moods works out your score
Lumi Moods blends recent sleep, HRV and resting heart rate against your own baseline, not against other people. Your HRV trend can move the score up or down by up to 10 points. It needs about a week of data before the score means much, and the method is explained in plain words in the app.
What it is not
It is an estimate. It has not been clinically validated, and it does not diagnose, treat or prevent anything. Lumi Moods is a wellness app, not a medical device.
What you need
An iPhone, ideally with an Apple Watch recording sleep and heart data. Lumi Moods is not planned for Android or iPad at launch.
