As more technology firms produce wearables, apps and connected medical devices that claim to help people live better or treat diseases, we need to draw a line between digital wellness and digital medicine. The entire health care industry needs to implement rigorous standards that can help differentiate between truly therapeutic products and the digital equivalent of snake oil.

Researchers believe they have developed an app that can tell if you are depressed simply by monitoring how you type and interact with the screen. Companies are pushing home versions of medical devices for detecting respiratory diseases in children, spotting chronic obstructive pulmonary disease, and testing urine that all claim to deliver clinical data.
