【實用工具app】Electric Sign|最夯免費app-gigacircle

Electric Sign is a simple application that lets you use your Android device as a self-updating electronic billboard.

When started, Electric Sign will download and display a user-specified web page, then go to sleep for a specified number of (minutes/hours/days). It will then wake up, re-download and refresh the web page, and go back to sleep again. This cycle will repeat indefinitely.

Electric Sign will work on any Android device, but it's especially well-suited for devices with electronic-paper displays (such as the Nook Simple Touch), because these devices require no power to display a static image. This allows them to run Electric Sign for weeks or months at a time on a single battery charge.

Note for Nook Simple Touch users: Be sure to choose "Electric Sign" as your screensaver preference in the Nook Screen settings (that option will appear there after the first time you run Electric Sign). That way your web page will remain visible even after the Nook has gone to sleep.
