Good app for legendary FICS! No adds. On good way to be first choice for playing on FICS via android. But 4 stars due to few improvements required: pgn file folder is not acessible with android 13, so how to transfer game played to other analysis tool? please provide 'copy pgn' of played game to clipboard, at least. Not user friendly to type 'accept' in console in case of manual accept, need improvement.
