Apple Health Step Data Sources
Yesterday I spent some time looking through Apple Health Data Sources. I see that there are plenty of data sources. These are the Apple watch, the iphone, Alltrails, move, connect, stepsapp, pacer, Suunto, Ingress and three more that are marked as inactive.
Move is the app that gets data from some Casio watches. Connect is Garmin connect and gets step data from Garmin devices. If I take steps and they are logged with a casio or a garmin device they do not count in iOS apps but if I take steps with Garmin and Casio devices without also wearing the Apple watch the same steps are not counted.
