Wearable device apps provide SimplyMe with a ‘snapshot’ of your activity. Some details are provided, others are not – and we can only work with what we’ve got.


Additionally, the methods we use to analyse your data might be different from the ones your device app uses to calculate your exercise intensity. We take into consideration a number of factors such as your age, gender, body mass index and heart age to identify when your heart is pounding versus when it’s at rest.


This means that, from time to time, your exercise minutes will show up differently in your two apps. The main thing to remember is: as long as you keep moving, you’ll be well on your way to that green rating.
