What is the main difference between Widgets and Apps?
Although widgets can be seen as part of an application (and are actually mini apps), they are not the same. The main difference between them is that widgets can be run automatically from the Home Screen without manually calling them.

Sample of an Android Weather Widget
When and Why to use Widgets
Using Android Widgets you could save:
- Time
- Money
- Battery Life
- Memory Space
Let’s see an example: If you need to check the weather you would probably open the browser, then you would search for a weather website and finally you would check the weather in your city. It would probably take you 5 minutes, but if you had an Android widget it would have only taken you a one-touch action.
By using an Android Widget in the example above you would have saved:
Time: The Android Widget takes less than a minute to check the weather.
Money: If you have a limited data plan you will save considerable amount of downloaded data.
Battery Life: As stated before, with a Widget this action takes less than a minute, against the five minutes it takes doing it the longer App way.
Memory Space: As Widgets are smaller than Apps you are saving device’s memory space.
Another key point to remark is that you would be using a widget for a particular and useful action (for checking the weather).
It’s very important to Give the Proper use to Android Widgets.

Thank goodness! An explanation that’s succinct and to the point! Thank you!
Finally, an answer I can understand instead of all that techie drivel which makes no sense.
