The ReSound Smart D app lets you control your hearing aids directly from your mobile device. You can change programs, and make simple or more advanced sound adjustments and save them as favorites. The app helps you learn what you can do and how to do it. It can even help you find your hearing aids if you lose them. Last, but not least, you can have your hearing care professional update your hearing aid programs and send you new hearing aid software without taking a trip to the clinic.
