PhoneScorer works with SnapScorer, an IOS based app for scoring Contract Bridge duplicate sessions. Each round one player running PhonScorer on their iPhone collects the score from each board played in that round. The scores are transmitted to SnapScorer wirelessly so that players can review scores from previous times the board was played and at the end of the session, see the overall results from the duplicate session. Say good bye to computer entry of travellers or manual hand scoring of duplicate sessions.
