How the estimate works

A planning model, not a store prediction

The calculator solves for the number of new ratings required to move a simple weighted average from the current score to the target score. It assumes the existing average and rating count are accurate and that future ratings arrive at the average you entered.

needed = current count × (target − current rating) ÷ (new-rating average − target)

Why the public store rating can differ

  • Apple App Store: the product page shows an overview rating by country or region, and developers can reset the overview rating with a new version. Written reviews are not removed by that reset.
  • Google Play: the public rating is weighted toward more recent ratings. Google also delays the public effect of new ratings while it checks for suspicious activity.
  • Both stores: displayed rounding, regional views, removed ratings, and user rating updates can make the visible result differ from a lifetime-average model.

App rating calculator questions

Are ratings and written reviews the same?

No. A customer can submit a star rating without writing a review. Use the total rating count shown by the store when estimating an average-rating change.

Does the calculator predict my exact App Store rating?

No. Apple displays overview ratings by country or region and allows the overview rating to be reset with a new app version. This tool models a simple average for planning.

Why can Google Play show a different result?

Google says the public Play rating is weighted toward more recent ratings, while the lifetime average is a separate metric. The weighting formula is not reproduced by this calculator.

What if my new ratings average is below the target?

A stream of ratings averaging at or below the target cannot pull the total average above that target. Choose a lower goal or improve the expected rating average.
