Lichess works quite well with mobile devices including tablets and phones. One way it could be improved is to increase the size of the buttons used in controlling game reviews. On a physical keyboard, going through your games is easy, but on a tablet, pressing the correct navigation button slows things down.
Perhaps the size and distance between the buttons could be increased. If desireable, lichess could detect the OS and do this only when it thinks a device is mobile.
