Tallymark: Pickleball & Darts

Keep score. Keep every score.

Tallymark is a fast, fully offline scorekeeper for pickleball, golf, darts, table tennis, badminton, volleyball and any game you can count. No account. No sign-up. Open it courtside and tap.

PICKLEBALL, RULES-CORRECT
Side-out scoring with proper 0-0-2 calls, server tracking and side switches. Rally scoring is included: both the 2026 rulebook version and the provisional 2025 variant. The scoreboard reads like a referee: the call string is always right.

DARTS
x01 (301/501) with double-out, bust handling and checkout suggestions from 170 down. Cricket with standard and cut-throat scoring, marks and spills handled correctly.

GOLF SCORECARD — OFFLINE, NO GPS, NO SUBSCRIPTION
Strokes, Stableford points and a running over/under for 1–4 players, 9 or 18 holes. No course database, no account, no GPS draining your battery — the phone lasts the round.

TABLE TENNIS, BADMINTON, VOLLEYBALL
A rules-correct scoreboard for each: the table tennis scoreboard swaps serve every two points and handles deuce; the badminton scoreboard plays rally point to 21; the volleyball scoreboard tracks sets and side switches. Serve rotation and end changes are the engine's job, not yours.

ANY GAME
The universal scorer counts anything — card nights, board games, backyard contests. Configurable buttons, round entry, target or open-ended play — with ready-made presets for popular card and dice games like Uno, Yahtzee, Cornhole, Rummy, Skyjo and Farkle.

EVERY GAME IS REVIEWABLE
Tallymark keeps the full round-by-round story of every game. Made a mistake five rallies ago? Edit it. Everything downstream recomputes. Kill the app mid-game; resume exactly where you were.

RUN A ROUND-ROBIN NIGHT (Organizer)
A four-step wizard builds fair schedules for 4–24 players: balanced partners, balanced sit-outs, honest fairness readouts. Score courts live, drop players mid-session without losing finished rounds, share final standings.

SHARE WITHOUT A NETWORK
Results cards, schedule PDFs, and a QR code with the night's schedule — all generated on the device. Works in a gym basement.

Everything works offline. Your data stays on your phone; back it up to a plain JSON file you control.
