About
GameQuant records the App Store top charts every day in 170+ countries and keeps every snapshot. That turns a ranking, which normally shows only today's position, into a continuous record you can look back through.
An app page gives you its rank over the last 7, 30 or 90 days, how its ratings count and average moved, the full star distribution, and where it sits in every tracked country on the same day. Monthly download and revenue estimates for the US are included, published as an 80% and a 50% band instead of a single figure, because they come from a model rather than from Apple.
There are also comparison pages for putting several apps on one chart, and apps grouped under the listed company that owns them.
Every page is public. No signup, no paywall, and the data runs to the previous day. Charts can be embedded or reused anywhere as long as you keep the source line and link back, and the chart image refreshes itself daily.
Coverage today is 210,000+ apps across 170+ countries on iOS. Google Play, Steam and the console stores are being collected and will appear on the public pages over time.
