Hello @Ericf, thanks for joining us, it's great to have you on board. 
Are you able to see your heart rate on your tracker? How often do you sync it? Keep in mind that the heart rate shown on the app is not a representation of your actual heart rate, the one showed on the tile is your average heart rate and it's displayed after you sync.
Additionally, please remember taht your tracker should usually rest a finger’s width below your wrist bone and lay flat. If you're exercising, please try moving it up one or two inches and remember not to wear it to tight around your wrist, this can also cause the tracker to not meaure your heart rate correctly. If this doesn't do the trick please restart your tracker.
I hope this can be helpful, in case you need anything else, feel free to reply!
