GWENT: The Witcher Card Game will be released on smartphones later this year. This release will bring all of the intense card flipping action to your fingertips when the game arrives on both iOS and Android devices at some unspecified date later in 2019.

I should note here that it seems as though the iOS version will be out first. I'm reading that "details regarding an Android release will be announced at a later date." Of course.

“We’ve been preparing long and hard to adapt GWENT to smartphones,” said Jason Slama, Game Director of GWENT: The Witcher Card Game, CD PROJEKT RED. “Beautiful visuals aside, we’ve tailored much of our technology, including GOG Galaxy which powers GWENT’s multiplayer, to support mobile devices. I think our vision for bringing GWENT to smartphones combines the best we have to offer both in terms of graphics and gameplay. I can’t wait to share more details on the subject with you later this year.”
Also, don't forget that the Crimson Curse expansion is out tomorrow, March 28.
