Question 1

What are App Store charts?

Accepted Answer

App Store charts rank apps by their relative position in Apple's App Store and Google Play across categories like Top Free, Top Paid, and Top Grossing. We mirror the public chart RSS feeds from both stores every 4 hours.

Question 2

How often are charts updated?

Accepted Answer

Chart positions are refreshed every 4 hours from Apple's iTunes RSS API and Google Play's category endpoints. Each snapshot is persisted so you can look back at historical rank movement on any tracked app's history page.

Question 3

Which countries are covered?

Accepted Answer

We mirror App Store charts for 150+ countries supported by Apple, and Google Play charts for 100+ countries. Use the country selector to switch the view.

Question 4

Why does the ranking differ between Apple and Google?

Accepted Answer

Apple uses different chart algorithms than Google. Apple ranks by recent download velocity within a country and category, while Google blends downloads, retention, and engagement. The same app can rank #1 on App Store and outside the top 100 on Google Play in the same country.
