Field notes
The homepage says overlapping Apple report files are deduplicated, recent data is marked provisional, and privacy-thresholded counts are flagged. It also describes reconciling Apple, RevenueCat, and backend figures, with mismatches surfaced rather than hidden. A sample app with 90 days of data is available to explore without API keys; connecting a user's own apps requires credentials.
