The Envi applications are a line of topic-specific Web-image browsers for the iPhone and iPod touch. Each app in the series provides access to Web images within one category. Envi products are based on the more general iEnvision iPhone Web-image browser.

• In-app purchasing - Purchase additional related content for an Envi app, from within the app itself.
• Music - Add one or more music tracks to play during a show, on a show-by-show basis.
• Double-tap zoom - For iPhone OS 3.0 and later, double-tap an image to zoom it.
• Automatic updates - Occasionally, shows develop problems due to changes in the Web sites they're based on. An Envi app will automatically update its content with "repaired" shows, as the we-envision team makes them available.
• Message of the Day - Notification, from within an Envi app, of the latest news regarding the app.
