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. No network. Open it courtside and tap.

PICKLEBALL SCOREKEEPER, RULES-CORRECT
Side-out scoring with proper 0-0-2 server calls, server tracking, and side switches. Rally scoring too: the 2026 rulebook version and the provisional 2025 variant. The pickleball scoreboard reads like a referee, and the call string is always right on every rally. Play games to 11, 15, or 21, win by one or win by two. Ends switch on the correct point so nobody has to do the math mid-game. Big tap targets and a big score you can read from across the court. This is the pickleball scorekeeper you reach for when the game is already on and your hands are full of a paddle.

DARTS SCOREBOARD: X01 AND CRICKET
x01 darts (301 and 501) with double-out, bust handling, and checkout suggestions from 170 down. Cricket with standard and cut-throat scoring, marks and spills handled correctly. The darts scoreboard keeps up with the board: tap the numbers and it tracks whose turn it is and what each player needs to close. Three darts a visit, running totals, no scrap paper on the oche. Undo a misread throw in one tap. Grind out a 501 leg or score cricket down to the last mark, and the darts scoreboard does the arithmetic while you throw.

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. It is the golf scorecard for a walking foursome: open it on the first tee, tap strokes as they happen, and the running over/under is always current when you shake hands on eighteen.

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. Whether you need a table tennis scoreboard for the office table, a badminton scoreboard for the gym, or a volleyball scoreboard for the sand, the rules are already loaded and the score is one tap.

A COUNTER FOR ANY GAME
The universal counter scores anything you can count. Card nights. Board games. Backyard horseshoes. Laps at the track. Configurable buttons, round entry, and target or open-ended play — with ready-made presets for popular card and dice games like Uno, Yahtzee, Cornhole, Rummy, Skyjo and Farkle. It is a tally counter that actually remembers, so you are not thumbing a metal clicker and hoping you got the number.

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. Close the app in the middle of a game and resume exactly where you left off. Nothing gets lost because your phone rang or the battery died.

RUN A ROUND-ROBIN NIGHT (ORGANIZER)
A four-step wizard builds fair round-robin schedules for 4 to 24 players: balanced partners, balanced sit-outs, and honest fairness readouts you can show the group. Score courts live as each round finishes. Drop a player who has to leave early without wrecking the rounds already played. Share the final standings when the last point lands. It is a round-robin generator and a live scorekeeper in one app, so the organizer is not juggling a spreadsheet and a scoreboard.

SHARE WITHOUT A NETWORK
Results cards, schedule PDFs, and a QR code with the night's schedule, all generated on the device. Hand someone the QR code and they have the whole bracket. Works in a gym basement.

Everything works offline. Your data stays on your phone, and you can back it up to a plain JSON file you control. Free to use with ads. A one-time purchase removes them. No subscriptions.
