If you notice that your moderate or intense exercise minutes are not being registered by the VitaBuddy app, the most likely cause is that you are not turning on ‘exercise mode’ on your Delta. This is definitely something you need to do to ensure your ratings are accurate!
To turn on the exercise mode please follow instructions here. Please remember to turn on exercise mode every time you exercise so that VitaBuddy can access every single one of your sweaty minutes!
