The recent mHealth Summit near Washington, D.C., was an eye-opening showcase of the latest in mobile health technology. This included several companies not normally thought of in the mobile space, including Aetna (AET) and Johnson & Johnson (JNJ 0.85%).

These two giants have joined forces; Aetna will use the Care4Today Mobile Health Manager mobile app, developed by Johnson & Johnson's Janssen Healthcare Innovation group, into its CarePass Platform. Motley Fool analysts Max Macaluso and Rex Moore were at the summit, and spoke with David Tripi of J&J's Janssen Healthcare Innovation and Martha Wofford with Aetna's CarePass. In this video, Tripi and Wofford explain why their companies are deeply involved in mobile health.
