Furthermore they sympathetically state: "Lichess mobile is developed and translated to 80 languages by volunteers. Just like the website, it's 100% free forever, and there will never be advertisements. This is humanist software, made open source for the love of chess and user freedom."
But there are two things on my wishlist 1) make the website work off-line 2) new variant to change the chess rules to accommodate a smaller board 5x6, 4x5 or 6x6 for even shorter games.
