The Bitcoin Widget is one of the most popular information-monitoring mobile applications available today, and its simplicity and accuracy have earned it high marks from users on the major cryptocurrency forums. In mobile tech parlance, a “widget” is a small and simple app that displays an icon on the home screen of a smartphone or tablet computer—and that's just what the Bitcoin Widget does. The icon it displays shows at a glance what the current value is of either Bitcoins or Litecoins, according to the user's favorite digital currency exchange (if they wish to monitor more than one exchange, the widget can be downloaded again, and the new version can be set to that exchange; both icons will show up on the home screen). The icon is color-coded: red if the value has dropped, green if it has risen, and yellow if it has remained steady. Tapping the widget icon will show the user a 24-hour graph for that currency's market activity. The Bitcoin Widget automatically updates every half hour, so traders will always have up-to-date information. It's a simple and straightforward way for digital currency investors to keep tabs on its value.
The Bitcoin Widget was developed by XBT Apps, which is headquartered in London, England (XBT is the European abbreviation for Bitcoin). The widget was released late in 2012.
