The ASO weather report is showing turbulence in the Google Play App-Store rankings over the past 30 days.
The higher the value, the more Google Play rankings have changed.
ASO weather is based on the top 100 ranking changes of ~600 most popular google play keywords in English language.
The Google Play ranking data is fetched from a German server.
The ranking report will be generated every day and is available for free.
The chart is always scaled by a dynamic scale factor to normalize the values between 0 and 100. So the day with
the most changes in the Google Play App-Store rankings over the past 30 days will always be shown as 100 even if
there is only on minor change in the ASO rankings.
