A Smartphone App And A Paper Funnel Could Help Parents Diagnose Kids’ Ear Infections

Researchers are developing a smartphone app that, with the help of a simple paper funnel, might help parents detect fluid buildup in a child’s ear — one symptom of an ear infection.

The app is still experimental and would require clearance by the Food and Drug Administration before it could hit the market. But early data, published Wednesday in Science Translational Medicine, suggest that the smartphone can perform as well as an expensive test in a doctor’s office.
