Hi, "surtitles" are subtitles shown in theatre shows and opera. Its key goal is to increase accessibility of performances, mainly for foreign speakers and visitors with reduced hearing. This app not only resolves the pain of creating and translating surtitles, but also allows screen subtitles (also) into mobile devices. Screening to projection can be adjusted in multiple different ways (colors, fonts, positions, ...).
Main competitive solution now is PowerPoint.
I'd be glad for your suggestions and recommendations. Thanks! ;]
