Frequently asked questions
- Where does the ranking data come from?

- How often do rankings update?
- Each (country, category, ranking type) combination refreshes once per day. Individual app metadata refreshes when an app enters a chart, when its position changes, or when a user visits its detail page.
- Which countries and categories are covered?
- 114 storefronts, from the United States to Zimbabwe. All 22 published App Store categories. Top free charts daily; top paid and top grossing are not collected yet.
- Do you track Android apps or the Google Play Store?
- No. App Store Tracker is iOS-only. The Google Play Store uses a separate ranking methodology and is out of scope.
- Do you estimate downloads or revenue?
- Apple does not publish per-app download or revenue figures. Revenue and download figures inside the product are third-party estimates. Treat them as directional.
- How far back does ranking history go?
- Daily chart history goes back to 2025-03-09. For each app it starts on the first day the app entered a tracked chart.
- How do I report a data issue?
- Email issues to the contact address on the About page and include the app URL, country, and what looks wrong. Corrections are typically applied within 24 hours.
