Transparent Glass Clock Widget for Android devices, Fidelity Market Monitor Widget for Mac OS X computers and Launcher for iOS devices are three examples of free widgets. A widget is an interface element that displays certain information or provides additional functionality.
The Transparent Glass Clock Widget displays weather a forecast on the homepage of Android devices. It can load weather data from multiple sources, update every 15 minutes and detect the user's location automatically. The widget is highly customizable, as it lets the user change the font of the time indicator, the theme and the weather icons, as well as set weather update intervals.
Fidelity Market Monitor allows users to view the current prices of stocks and changes in stock prices. The widget displays each change in price both as a nominal amount and as a percentage. It can monitor 25 different stocks at the same time, display price data as a chart and gather recent news about a stock.
Launcher allows the user to open applications and perform various tasks directly from the Notification Center. Users can search for nearby places, get directions, quickly access their favorite websites, see weather forecasts and play music. Moreover, the widget can call and send text messages to frequently contacted friends and use social media functions. While there is a Pro version that adds more rows to the Launcher, all functionality is free to use.
