Securely and privately manage Bitcoin, altcoins, and fiat currencies on your personal computer with our software.

Privacy is highly valued in this application, and no data whatsoever is sent out from your computer except for the necessary signal to fetch the latest rates securely from the servers. Moreover, it works offline through the use of the last loaded rates.
The polished and sleek interface comes with the right amount of natural features, making it easy to use for anyone. The powerful underlying math engine supports various non-monetary units, allowing for all sorts of useful conversions in the same manner, such as '1 cup to dl.'
It's worth noting that this application will never send your private calculations to a third party, ensuring maximum privacy. And, best of all, the application is now free of charge!
Version 2: This version (2) is the first free version. Version 1 used to be sold. There are numerous small improvements, and a text 'ad' (currently just asking for donations, and will never link to anything fishy/evil) was added.
