Tired of launching the macOS Calculator app and stepping through menu paths just for doing a simple currency conversion? Missing cryptocurrencies in Spotlight's currency conversion feature? Annoyed by the limited curreny selection of both of these system features? Here's the solution:
"Exchange Rates" is a small currency calculator residing in the macOS status bar and/or in your notification center – always available and always up to date. Nothing more, nothing less.
Everything can be done using keyboard shortcuts, so you can easily convert an amount between two currencies without interrupting your current workflow by using the mouse or even launching another window-based application. It also provides two system services to make currency conversions even more convenient.
All exchange rates are being updated continuously in the background, so you don't have to do anything about it. In addition, the fixed exchange rates of all euro predecessor currencies are available, such as the Austrian Shilling or German Mark. And just in case you would like to know what your paper currency is worth in sound money: Exchange Rates also offers four precious metals for conversions - each in grams and troy ounces.
Exchange Rates can also notify you automatically with a notification when a predefined threshold of a currency pair is de- or exceeded. This feature is available for all supported currencies (including various cryptocurrencies) and the 4 precious metals (either in grams or troy ounces).
The most important features at a glance:
• All important world currencies
• All euro-predecessor currencies
• Precious metals (gold, silver, platinum, palladium)
• Various cryptocurrencies with builtin support for Bitcoin, Bitcoin Cash, Litecoin, Ethereum, Ethereum Classic, Monero and Ripple
• Several different exchanges for each cryptocurrency
• Allows you to add other, missing cryptocurrencies as well as custom feed definitions for price feeds from other exchanges (JSON via http or https)
• Today widget for your notifiction center showing a list of your favorite exchange rates as a list view (see note below)
• Exchange rate notifications
And there is even more:
• everything can be done using keyboard shortcuts to avoid interrupting your workflow.
• official LBMA fixing prices for gold and silver loaded via quandl.com (this requires a freely available Quandl API key)
• precious metals can be shown either in grams or troy ounces
• two system services (convert to local currency or to all currencies in your favorite exchange rates)
• a command line interface for currency conversions
• data minimization: no unnecessary data collection (e.g. user tracking)
• uses encrypted https connections for all built-in data sources
A note regarding the Today Widgets: Due to the profound technical changes in macOS, the two other widgets which were previously included in this app - the currency calculator and the favorites widget in a tiled view - are only available on macOS Catalina and the previous versions. These changes also don't allow for any interactions in today widgets, so it unfortunately is not possible to implement a replacement.
Please note: Exchange Rates is a research tool, it cannot trade foreign exchanges on your behalf. It is however a fantastic tool to keep an eye on the market, so all exchange rates and precious metal prices are provided for informational purposes only, and do not constitute financial advice of any kind
