Use when someone asks whether an Apple Ads or subscription metric is unusual, what CPA/CPT/TTR/CR was published for a country, App Store genre, or niche, how Apple Ads subscriber economics compare with other paid channels, or what uplift the 2026 report measured for Custom Product Pages and keyword-matched paywalls. Also use when someone says CPI: this report publishes CPA per download, so the denominator must be clarified before comparison. Reads local CSV files and needs no account, CLI, network access, or subscription.
