旅行记账能手

????你可以在这款应用中输入自己的旅行预算限额（或通关时的免税额度）。购物的时候则可以输入购物金额的外币价格，它会自动转化成你的本国货币，然后还会提醒你离预算限额还差多少。你还可以给购物发票拍照片，然后把整个购物清单用电子邮件发给自己。功能虽然不丰富，但的确很有用。

价格：1.99美元

Simply Declare

????Put in your spending limit for a trip (i.e. the duty limit you're facing at customs). As you make purchases, enter them in the foreign currency; it converts them to your home currency and keeps a running tab of where you stand against the limit. You can also include pictures of your receipts, then e-mail yourself a document with the whole list. Pared-down, but effective.
