You can set custom zones from the web page - https://www.fitbit.com/settings/profile under personal info > heart rate zones
Best Answer@InspireUser_ Fitbit gives you the ability to set custom heart rate zones, but it doesn't notify you when you cross your zones. I looked at your public profile and saw that you gave feedback using the Product Feedback forum. This is the way to give feedback asking for a feature.
@MercyP You can still get to that page, but you can't make changes from it since Fitbit deactivated the web dashboard. If you want to turn custom heart rate zones on/off or change them, you must do it in the mobile app. Tap on your profile picture/gear icon > Heart rate and make changes there.
