realexchangerate
A simple hybrid application built with Ionic Framework and Open Exchange Rates API to get Real Time Exchange Rate with historical exchange rate support.
Only the necessery files are included [index.html, app.js, money.js], please replace them after creating the blank application using Ionic Framework. money.js is maintained by Open Exchange Rates http://josscrowcroft.github.io/money.js/
If you are interested to check how to setup the environment for Ionic Framework or how to created the blank application you can check my blog post http://blog.shiefuzzaman.com.
For real time exchange rate I have used the api from https://openexchangerates.org/. Besides their paid plan they are also offering a forever free plan with 1000 Request/Month.
