Calculated by Tech Dev Notes
These numbers are derived from our own tracking data — sparklines, deltas, peer comparisons, and cadence are computed by us, not provided by Apple. Raw store data lives on the app detail page.
ChatGPT holds steady at #2 US, rating climbed 0.04★ this week, gained 148.6K reviews, and charts in 169 countries (best: Antigua and Barbuda #1).
Methodology: Tech Dev Notes snapshots App Store data every 4 hours. Sparklines reflect the last 30 days of recorded snapshots. 7-day deltas compare the latest snapshot to the snapshot closest to 7 days prior. Release cadence is the average gap between consecutive versions in our log. Peer-group comparisons use other apps in the same primary category that we track. None of these numbers come from Apple — they are computed from our tracking data.
