There are these physical chess e-boards called DGT (). You connect by bluetooth to your computer, and they can send your moves to live chess games on e.g. lichess.org. I wrote a hacky iOS companion app for this, so that I don't have to look at my computer while playing online games. The way it works is: - you turn on your dgt chess board - you log into your laptop, connect it to the board, and start a game - you start the mobile app and can ignore the laptop, and the mobile app shows a game clock and alerts you to moves by your opponent DGT board <—>laptop<—-><—->mobile app The idea is that this feels more like an in-person game with a chess clock than having to look at the computer. I wrote this in swift and am not
