#10 Greta & Starks. This app is hugely popular in Europe and they're coming to the United States soon. Deaf or hard of hearing people can simply enjoy films in theaters and/or in their own homes with Starks displaying captions and subtitles on your smart device (this is a German company, thus their website is in Germany, however, on the the top right corner just click English to read more). In Europe, most of the captions are actually placed on "data glasses". The app is super easy to use. Simply use your own smart phone, tablet, iPhone, iPad or iPod touch and you don't need a internet connection. (You can use it at home or on while you're on a flight to another country!) Greta & Starks is diligently working on data glasses to display the subtitles much more comfortably to enhance your movie theater experience.
