Platform Choose the store model to use. Current rating count Auto-filled from the store. Google Play math uses the effective base below. Current exact average The real average used for the math, not the rounded store display.

Google Play weighting estimate

Google Play does not use a simple lifetime average. We estimate the active rating base from recent rating pace. Edit this only if you know your recent ratings per day.

Recent ratings per day Use your real recent daily rating pace if available. Recent rating sensitivity Higher sensitivity means recent ratings affect Google Play faster. Effective rating base Decay-adjusted active rating base used instead of lifetime ratings.
