Rating – Stars
It works like this:
For each item, a rating of (usually 5) stars is displayed. This rating is the average of all ratings given to the item.
In a detailed view for the item, the possibility for rating is shown. From left to right the rating is shown by highlighted stars. Notice how the rating doesn’t have to show completely highlighted stars, but also half highlighted stars to add more nuance to all ratings. When the user taps the stars…
…a dialog appears for rating the item. The user can assign a number of stars by tapping them, and save the rating.
Ratings can be used when you want the quality of content to be judged by its users. The amount of stars given by other users matters when the user has to make a choice for downloading or opening an item. A high rating (a lot of stars) will persuade the user more likely to make the download. Usually, 5 stars are used to give a big enough rating range. As explained above, the displayed rating can also show half highlighted stars. Don't forget to add the number of ratings somewhere to make the rating actually valuable. An other way to let users give their opinion on items is by liking or disliking or commenting.
- It's a quick way for users to add a rating
- Adds value to your app's content, because the user gets involved in giving his opinion.
