What's better than PowerPoint or Google Slides for a TV menu?

PowerPoint and Google Slides are cheap but weren't built for always-on displays. They usually need a computer connected to the TV, manual casting, and someone to re-cast after a reboot.

A signage app like Dispry installs right on the TV device, runs on its own, relaunches after a power cut, and updates remotely from your phone. You get instant updates, portrait support, video and slideshows without a PC babysitting the screen.
