no. zochess is real-time only, so there are no daily or correspondence games.
each player has 60 seconds of total offline time per game. reconnecting does not refill it, and if it runs out your opponent wins by abandonment. when you reconnect you are back in the same game.
yes. in online games you can offer a draw or ask for a takeback, and your opponent decides. you can also abort a game before the second move.
yes. you can play stockfish at five levels. those games are private, unrated and untimed, and they save so you can pick them up later.
yes. add friends, message them and challenge them to a game.
yes. you can follow live games with a short delay.
yes. puzzles from the lichess database adapt to your puzzle rating, and your progress is tracked.
after a game, open the analysis to see the evaluation and the best moves. stockfish runs on our servers, so nothing heavy runs on your phone.
yes. sign in with the same account on your phone and in the other zochess apps.
