Chalkline: Bridge Scorepad

Rubber bridge, scored clearly. Chalkline turns your iPhone or iPad into a precise, private scorepad for a complete rubber bridge night. Seat four players, enter each result in bridge language, and let Chalkline keep the game line, vulnerability, premiums, totals, and final margin straight. SCORE THE WHOLE RUBBER • Record contracts from one club through seven notrump • Handle doubles, redoubles, overtricks, undertricks, honours, and passed-out deals • Track game progress and vulnerability automatically • Score small slams, grand slams, rubber premiums, and unfinished-rubber credits • Tap a figure to see what it means and why it was awarded FIX MISTAKES WITH CONFIDENCE Preview the full effect of a correction before saving it. Chalkline shows how the change moves the game line, vulnerability, later deals, and settlement instead of silently changing the total. KEEP THE NIGHT TOGETHER Follow every player across rubbers, rotate partnerships, review the night, and seal agreed figures. Portable JSON backups can be saved, shared, and restored when you choose. LEARN AT YOUR OWN PACE New to rubber bridge? Play through an interactive practice rubber covering the auction, following suit, above- and below-line scoring, vulnerability, doubles, penalties, honours, and slams. A complete rules reference, tables, common mistakes, and worked examples stay beside the scorepad. PRIVATE BY DESIGN Chalkline works without an internet connection. It has no account, ads, analytics, tracking, or cloud service. Player names and score history stay on your device unless you explicitly export a backup and choose where to send it.
