AppPriceData
Observed local App Store prices with one dated reference-currency comparison.
Across 5 observed Apple App Store storefronts, Computer Science Calculations is free to download in every stored observation. Each country row keeps its own storefront and observation date.
Local storefront prices remain the source records. USD values are informational reference conversions from one dated exchange-rate snapshot and can differ from taxes, card settlement, or final checkout pricing.
Rows are sorted by the USD reference conversion when a supported exchange rate is available. The local price and currency remain the original source values.
