Ear infections are a common ailment among children and historically have required a trip to the pediatrician, causing stress and inconvenience for families. SmartCheck™ is a simple device and companion app that turns almost any smartphone into an otoscope, enabling parents to record a video of the eardrum and share it with a healthcare provider for at-home diagnosis. The mobile app features step-by-step instructions and a patented Eardrum Finder with audio instructions to assist parents in safely finding and capturing a visual of the eardrum and to review past ear recordings with their doctor.
