Rate
App Rate/ App Rating - a star point from 1 to 5 that a user gives to an app to indicate what they think of the app. It's very helpful for other users who are considering downloading the app and is therefore an influential factor for how well your app is ranked overall on the app store.
The more positive rates an app gets on the store the better it ranks in categories and keyword ranks. As a result higher rank increases organic installs and affects the effectiveness of the promotion.
