The Route widget allows you to do basic route tracking; it provides an exmaple of how WRT widgets can access phone services, in this case the GPS. The widget displays location, distance, speed and time information. Route will only work on S60 5th Edition devices (those that support platform services).
The AccuWidget is a basic weather widget (current conditions and forecast). It uses publicly available RSS feeds and is a good example of how a WRT widget can create a rich client experience for a basic web service. AccuWidget will run on all S60 devices that support WRT.
Both widgets also demonstrate how to implement 'dynamic scaling to different resolutions and orientations by modifying the CSS styles on the fly, and showing transition effects when switching between views'.
In miniview Route shows the distance travelled and current speed in miniview, while AccuWidget shows a summary of the current weather.
