A weight management app helps consumers to systematically collect weight information, food consumption information and exercise information. Weight can be entered manually, or a consumer can link a wireless scale to the app so that weight is automatically collected when using the scale. Food consumption is entered manually, and the tool estimates calories consumed based on the consumer’s input. Exercise information may be entered manually or collected automatically through integration with a smart watch. A walking app collects data based on how far someone walks, using GPS technology. A consumer can view a history of walks taken and summary statistics related to distance walked and estimated calories burned. App developer is not a HIPAA-covered (see reference below) entity (CE) such as a healthcare provider, nor is the app sponsored by a CE (such as a hospital or physician).
