旅遊匯率計算小幫手（匯率計算機） 1.07.02

Reminder: The newly added custom exchange rate feature allows you to set the "Custom Exchange Rate Name" and "Custom Exchange Rate Value" by clicking on the custom exchange rate name in the settings screen. The exchange rate value is calculated based on the New Taiwan Dollar benchmark.

Introduction:

The operation of the app is designed to be fast and simple, whether it's addition, subtraction, multiplication, division, adding or subtracting taxes from product prices, currency switching, or even displaying three to four country exchange rates together. Users can customize the displayed decimal places on a single screen without the need for multiple inputs or switching back and forth.

The interface is simple and clean, without a logo screen to delay startup time or annoying ads taking up screen space.

Travel made simple.

Features:

1. Supports exchange rate information for twenty countries provided by Taiwan Bank.
2. Through the value-added tax button, users can quickly display the amount after tax deduction or addition on the screen, and customize the tax rate for each currency.
3. Exchange rate calculations use Taiwan Bank's "cash selling" rate; if a country doesn't have a cash selling rate, the "spot selling" rate will be used (e.g., South African Rand).
