Why Country Matters for App Rankings

The same app can have wildly different ratings across markets. A banking app that works flawlessly in the US may struggle with local payment integrations in Japan. A streaming app may have a rich content library in one country and a thin one in another. Country-specific rankings surface what users in Japan actually experience, not what marketing pages claim works globally.

Our methodology divides negative reviews by total ratings on a per-country basis. An app with 100,000 ratings in Japan and only 200 negative reviews (0.2% complaint rate) is genuinely loved here. The same app may rank differently in another market depending on local pricing, language support, and feature availability.
