The breakdown of an app's reviews across the 1-5 star scale, expressed as counts or percentages. A 4.8★ average can come from many shapes — 95% 5★ + 5% 1★ (polarized), 75% 5★ + 20% 4★ + 5% other (consensus), or a long tail of 3-4★ reviews (lukewarm).
Also known as: star rating breakdown, review star distribution, rating histogram, rating breakdown, star rating spread
The distribution shape matters more than the headline average for long-term trust; a polarized listing usually has a feature gap or a setup friction that triggers occasional 1-star outliers, which compound over time into a steeper churn curve. AppRanks displays the distribution as a horizontal bar chart on the ratings & reviews section of every app page, and the audit page surfaces it under "Rating health". Compare the same shape across competitors: an app with the same average rating but cleaner distribution is usually the safer choice for new merchants — fewer angry-review surprises after install.
The headline rating compresses too much information — a 4.8★ average from a polarized base (95% 5★ + 5% 1★) implies a different install risk profile than the same average from a consensus base (75% 5★ + 20% 4★ + 5% other). For new merchants, a polarized distribution typically signals a feature gap or onboarding friction that triggers occasional 1-star outliers and is worth investigating before install. For developers, the distribution shape over time tracks whether product fixes are reducing the long-tail negative-review pattern.
