TappedOut.net MTG Companion is a free Android app developed by Stephen Yeago for Magic: The Gathering (MTG) players. This app provides a range of features that can help users manage their decks, stay up-to-date with MTG discussions, and even recognize their collection through an experimental camera app.

One of the app's most significant features is push notifications that keep users updated on discussions happening on the TappedOut.net site. The app also allows users to cycle their decks to the home page of the site, making it easier to access and edit their decks. Additionally, the experimental camera app can recognize users' collections and add them to the site.

It is essential to note that TappedOut.net MTG Companion is not meant to replace the website. Users should carefully read the features before installing the app, as it may not meet their expectations. However, if users decide to install the app, it is essential to keep it updated, as changes come frequently. If the app crashes, users can report the crash by hitting the report button and explaining what they were doing.
