Deck Builder for Netrunner is a free lifestyle application designed for Android devices. Created by Sébastien Huneault, this open-source project provides a searchable card browser for Netrunner players. With this app, you can filter the cards that you own and set a custom card pool for each deck.

One unique feature of this app is that it allows you to view all the cards in your deck in fullscreen mode. It also caches all images for offline viewing, which is particularly useful for players who travel frequently. In addition, the app includes MWL validation and supports all Nisei formats.

Deck Builder for Netrunner also enables you to import and export OCTGN (.o8d) files, although phone compatibility varies and may require the use of a third-party file manager. You can also download card and MWL data updates from the options page.
