Convert prices in the country youre currently in to your home currency. The currency to convert from is automatically chosen based on which country you are currently in—without needing a Wi-Fi or data connection (which you often dont have when traveling). Your home currency is based on your Phones region setting. If you are in your home country, you can manually choose a currency to convert from which is great when youre planning a holiday.
