The Ratings page counts every rating your app has received, whether they contain text or not. All of the other tools in Appbot only analyze Reviews that contain a text component. More information on the difference between Ratings and Reviews can be found here.
The results that you see on the Ratings page will therefore match the numbers you see on the iOS and Google Play stores.
Ratings for iOS apps
The App Store reports ratings for each country. By default, you’ll land on the country with the highest volume of Ratings when you land on this page. View data for all countries by opening the filter pane on the right (see 2 below) and clearing the Country filter.
For iOS apps the Ratings page is divided into two sections: All Time (see 1 below) and Current Ratings.
The ‘Current Rating’ matches the App Store, and reflects the rating since September 19, 2017 or whenever you last reset your Ratings via App Store Connect.
Here is Apple’s explanation:
The ‘All Time’ figures reflect all the data Appbot has ever collected for your app’s Ratings.
You can also view the count and average stars of ratings for a specific period (see 3 below). Just open the filter pane (2 below) and adjust the date range to show the period you want.
Ratings for Google Play apps
Only global, all-time metrics are available for Google Play Apps.
What if your Ratings Over Time Chart is blank?
App stores don’t provide ratings per day, Appbot has to collect the data and calculate it for you. We fetch data for all the top charting apps, but for smaller apps we’ll only start fetching and calculating ratings over time when someone starts tracking that app in Appbot.
How long will it take to show data?
We need a minimum of 5 data points for the chart to start returning data, so please check back in 5 days.
Why doesn’t ratings have the entire history?
The App Stores don’t enable us to fetch history for ratings. We snapshot ratings once a day from when the app is first tracked in Appbot.
Why do I see decreases in the Ratings Over Time Chart?
We sample the rating count you see on the iOS and Google Play app store pages.
The app stores calculate the rating count using proprietary algorithms that we have unfortunately do not have visibility into. This can cause fluctuations in the samples.
Another less common cause of decreases is reviews and ratings being removed.
This can be done at the request of the author or the app developer. Also sometimes the app stores do this if they detect spam reviews or ratings. Again, visibility into this is limited.
