Photodex has released its video slideshow app for the Apple iPad and iPhone, ProShow Web. The app lets users easily mix photos, videos, text and music together into professional-quality video slideshows. It integrates with popular photo sharing platforms so users can create videos by importing their photos from their Camera Roll, Instagram, Facebook, Flickr, 500px and SmugMug. The app is free to use for a 15-photo video. Unlimited, full-length videos start at $4.99/ month and plans can be purchased in-app. Photodex Proshow Web for iOS is available now on iTunes
