xChangr is an app which allows you to easily track how much you're spending based on your initial purchase price of any currency. You can add multiple currencies and view the rates easily from the home screen or calculate how much a meal or taxi, for example, is going to cost you in a currency you're more familiar with! By purchasing xChangr, you will avoid bad purchases due to miscalculations of the worth of an item, and in the long run it all adds up. Additionally, as xChangr uses the rate you purchased currency at, you won't require internet access to use it, which may be hard to come by in more exotic travel locations. Take a little stress out of your life, and travel with xChangr!
