I have seen chess apps that work as a chess clock. Are there chess apps that allow users to record moves and do not include a chess engine? The idea is to use the app during a chess tournament as a experiment. There are no economic prizes, so we consider the chance of cheating very small. Also, we are trying to educate people more than create world chess champions.
