nanDECK

nanDECK is a straightforward and simple application that makes it as easy as possible for you to design and print a deck of cards.

Well-organized and portable application

Since this utility is portable, you can carry it around with you at all times on a small portable device, but you can also run it on any computer without the need to install it. This said, you can easily open the app and start working on your card decks in a couple of seconds.
The first thing that stands out is the fact that nanDECK's main window does not come with a standard toolbar-based interface. Instead, all its functions are organized into two panels found on each side of the main window.

Simple menus, but somewhat complicated workflow

It soon becomes clear that nanDECK is not one of the most interactive apps out there and is mostly focused on command line and simple keywords. This said, maybe this is not such a bad thing, as the app can easily modify an already completed deck.
You can easily start new projects and scripts then validate them while checking the syntax. If you are happy with the results, simply press the 'Build deck' and, finally, click the 'Print deck' button.

Offers a surprising number of customization options

Besides offering you the option to save all your images from the project, nanDECK also makes it possible for you to export your deck card projects to PDF.
As far as customization options go, nanDECK enables you to change the file location, the buttons for validation, the default extension for the deck files. In addition, you can use in-line comments and enable the batch directive.

Creates custom scripts and multiple decks of cards

Taking all things into consideration, nanDECK is a handy and streamlined application that provides you with a pragmatic environment for building deck cards.
While not the most user-friendly application out there and mostly based on command line actions, nanDECK has a lot to offer, assuming you have the patience to discover that and do some reading about its commands beforehand.
