How to set App Store prices per country

Apple prices a subscription or in-app purchase from a fixed table of 800 price points per currency, and computes a comparable price for all 175 App Store countries and regions from whichever base price you set, adjusting for local taxes and exchange rates. Whatever number you type gets rounded to the nearest of those 800 points, not converted at a live exchange rate, so the price a shopper actually sees is whichever fixed point sits closest to your input in that currency. Google Play works from the same idea with different mechanics: it converts your price to each local currency, adds tax where required, and applies what its own documentation calls locally relevant pricing patterns together with the exchange rate that was valid on the date you set the price, rather than recalculating it continuously; you have to manually refresh a price to pick up a new rate. On both stores, the number you originally typed and the number a shopper ends up seeing can diverge once tax, rounding, and the store's own pricing pattern for that currency are applied, and neither store keeps a territory's price in sync with exchange rates on its own. What a price change does to an existing subscriber is a separate question from how the price itself is computed, and the two stores handle it differently. A price decrease on the App Store always reaches every current subscriber automatically, with no option to keep them at the old, higher price. A price increase offers a choice: keep existing subscribers at their current price and let them resubscribe at that price within 60 days if it lapses, or apply the new price to everyone currently paying the displayed price, with Apple handling the email, push, and in-app notifications either way, and for the second option, continuing to request each subscriber's consent until they accept or their subscription expires. Google Play works differently again: changing a subscription's price only affects new purchases by default, and every existing subscriber lands in a legacy price cohort and keeps renewing at their original price until you separately choose to move them, either through an opt-in increase that requires their explicit acceptance or, where eligible, an opt-out increase they're notified about in advance and can decline by cancelling or switching plans.
