Tired of launching the OS X Calculator app and stepping through menu paths or launching the fullscreen OS X Dashboard just for doing a simple currency conversion? Maybe even without having to move your fingers from the keyboard? Here's the solution:

"Exchange Rates" is a small currency calculator residing in the OS X status bar – 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 launching another window-based application.

And just in case you would like to know what your paper currency is worth in sound money: Exchange Rates now also offers precious metals for conversions - each in grams and troy ounces.




World Currencies

In addition to more than 160 worldwide currencies Exchange Rates also offers the current rates of IMF Special Drawing Rights and the U.S. Dollar Index as well.


All euro predecessor currencies with their fixed exchange rates are available as well, for example the Austrian Shilling or German Mark.


Exchange Rates also shows the prices for the crypto currencies Bitcoin, Litecoin and Ethereum. You can choose from a variety of supported currency exchanges: 26 for Bitcoin, 9 for Litecoin and 3 for Ethereum (version 2.6).
Other exchanges can be added easily in the app preferences (see the FAQ section for more informations about that).

Precious Metals

You can also check what your paper currency is worth in sound money: Exchange Rates shows the prices of the 4 precious metals gold, silver, platinum and palladium in either grams or troy ounces.


You can also create notification rules for any currency pair or precious metal to be notified whenever an exchange rate ex- and/or deceeds a specific threshold.

Today Widget

Exchange Rates also includes a today widget showing a list of your favourites and offering the most important functions like currency selection and conversion (available on OS X Yosemite and newer).

2 System Services

Exchange Rates is also available from within other OS X applications - like for example Safari - by offering two OS X system services to convert any amount to either local currency or to all your favourites without the need of copying and pasting it first. Keyboard shortcuts for these system services can be configured in the OS X system preference panel "Keyboards".

Track Your Favorites

Favourite lists help you to keep track of all your favourite currencies with their most recent exchange rates with various different list types for showing direct and/or indirect quotations - both in the status bar and the OS X notification center.
There are several different list types for the favourite lists shown in the status bar panel and the today widget. You can choose from types for showing the direct and/or indirect quotations against the currently selected source, target or local currency. Here are a few examples:

Always Up-to-date

Everything is updated automatically in the background, so the most recent rates are immediately available in the OS X status bar and the notification center (on OS X Yosemite and newer).

Simple & Efficient

Exchange Rates offers lots of keyboard shortcuts, so you can control basically all features of the app without the need of a mouse and thus interrupting your current workflow for a rather basic task like converting an amount to a different currency.


The user interface is focused on the essentials to keep it simple and its usage as efficient as possible. It helps you keeping track of all those currencies which are important to you - always available and always up-to-date. 

No unnecessary data collection

No user tracking or any additional data acquisition of any kind (e.g. via Google Analytics, Flurry etc.) is done by this app. The only network comunication done is for updating the exchange rates from the respective servers, these requests may be tracked by the respective server owner. The update frequency can be changed in the application's preferences, more informations about the loaded feeds can be found on the FAQ page.

  • The Today Widget requires the main statusbar app to be running
  • Only BTCe is available as bitcoin/litecoin market place
  • Custom BTC-,LTC- and ETH-feeds are not available
  • Notifications are not available
  • Launch at login setting inside the app is not available
  • Its runtime is limited to one hour per session. After that the tryout version has to be restarted
  • All application settings will be reset on application startup

To launch the tryout version immediately at login, you have to add it manually in the OS X System Settings (Users & Settings > Login Items).
If you should miss a feature or have any ideas how to make CalendarMenu even better, don't hesitate to add it to the bug tracker. Thank you!

From where do you load the exchange rates?

The exchange rates of all currencies (except the euro predecessor currencies) and the US Dollar Index are being fetched from Yahoo servers. They are updated with a delay (not realtime), please browse the feed for a complete list of all currencies and their dates.

Prices for silver, platinum and palladium are primarily fetched from Yahoo as well, but Gold and Silver prices can alternatively be fetched from Quandl, which requires you to create a free API key on their website www.quandl.com and enter it in the app preferences on the pane called "Debug" (see the screenshow below). The feeds loaded from Quandl will then contain the official LBMA fixing prices (London Bullion Market Association) which are set twice a day for gold and once a day for silver.

The euro predecessor currencies however are maintained manually, so changes (if a country should join or leave the euro zone) will require an update of the application.

Bitcoin and litecoin prices are loaded from the servers of the respective bitcoin/litecoin exchange. You can open the respective feed in your default web browser by clicking on the small arrow button next to the exchange selector.

All feeds use the same update frequency set in the application's preferences popover.

Please keep in mind that the exchange rates and prices shown by this app are only for informational purposes and are no financial advice of any kind. The availability, quality and accuracy of this data cannot be guaranteed, so please use it at your own risk.

    Although ExchangeRates is being developed with the utmost care and intensively tested before being published, I cannot guarantee the suitability of this program for any purpose not described on this website. No warranty can be assumed for the performance and flawlessness of the software for all usage conditions and cases and for the results produced when utilized by the user. ExchangeRates is provided "as is", without warranty of any kind.

    Please keep in mind that the release of new versions on the App Store takes some time to to pass the review process, so bugfixes will not be immediately available after the respective entries on the Bugtracker have been marked as "done". The current average review time of the App Store (as a rough guide value) is available on appreviewtimes.com.

    Errors happen and bugs may not always be found in time, so if you should find one in in one of my programs or if you are missing an important feature, feel free to add it to the Bugtracker.
