Methodology
- Rank. Position in Apple’s public “Top Free Apps” chart for the United States (top 100, iPhone), from Apple’s marketing-tools RSS feed, taken once a day. “Not in top 100” means the app was below rank 100; the feed does not show lower positions.
- Ratings. Number of ratings and average rating in the US App Store, from the iTunes lookup API. Counts include all versions of an app. Robinhood and Crypto.com are broad trading apps, and DraftKings, FanDuel, Fanatics and Underdog have separate apps for other products; only the listed app is measured.
- Limits. Chart rank reflects recent download volume across all app categories and moves daily. It is not a measure of trading volume or revenue. Apps and names are those listed on the App Store on the snapshot date. App icons and Apple artwork are not used on this page; Apple and App Store are trademarks of Apple Inc.
