Darts scoreboard for iPhone

The darts scoreboard
that folds.

Ninefold scores 501 and Cricket, calls your checkout and keeps every stat. On the iPhone Duo it stands up on the table: scores facing the board, keypad under your thumb.

Coming soon to theApp Store

For iPhone Duo and every iPhone on iOS 26 or later.

Ninefold oche mode: Alex on 141 and Sam on 216, checkout T20 T19 D12, with the keypad below the fold.
Oche mode: the top half faces the board, the keypad lies flat.

Made for the iPhone Duo

Fold it, stand it, open it.
The game follows.

The live game rearranges itself for however the phone is held. Ninefold reads the space it's given and where the fold sits, so it adapts as you fold, unfold or turn the phone mid-game. Score rings and keypad glide to their new places, and nothing is lost.

Ninefold in oche mode on the iPhone Duo: score rings for Alex (141) and Sam (216) and the checkout T20 T19 D12 on the top half, the keypad on the bottom half.

The scoreboard stands up on the top half, facing the oche. The keypad lies flat on the bottom half. Nothing is drawn on the fold.

Stand & Portrait

Turn the folded Duo, or any iPhone, on its side for scoreboard left, keypad right. Hold it upright for one column: scores above, keypad below.

Celebrations face the board

In oche mode a 180 lights up above the fold, on the half everyone at the oche can see.

Wide everywhere else

Home, stats, trophies, profiles and match summaries switch to a two-column layout on the unfolded screen.

Every iPhone

From the SE to the Pro Max.

No Duo? Ninefold runs on any iPhone. Sizes scale smoothly from the iPhone SE to the Pro Max, and every screen is checked on the SE, the iPhone 18 Pro and the folded Duo.

501 on the iPhone SE: score rings, checkout T20 T19 D12 and the keypad.
501 on the iPhone 18 Pro: Alex on 141, Sam on 216, with the full keypad.

Games

501 and Cricket, scored properly.

501 & X01

Pick the starting score (501, 301 and others) and whether you finish on a double. Busts are handled for you: the turn ends and the score goes back.

Checkout · 141T20 T19 D12

Routes favour the fewest darts, then common setups and the doubles players prefer: D20, D16, D8. Each player shows their 3-dart average, first-9 average, last score and a scored-and-left history for the leg.

Cricket

Close 15–20 and the bull. Singles, doubles and trebles count 1, 2 and 3 marks; outer bull 1, bullseye 2. Extra marks on a number you've closed score while your opponent still has it open.

  • 1 mark
  • 2 marks
  • Closed

The grid shows who's scoring on what. Each side shows points, numbers closed (2 of 7) and marks per round.

Cricket in oche mode on the iPhone Duo: Alex on 40 points and Sam on 18, with the marks grid for 20 to bull and the keypad below.

Singles, doubles, guests

Two players free, up to four in 501 with Pro. Play 2 v 2 doubles with partners taking turns (A1, B1, A2, B2). Guests can jump in without being saved.

Legs and sets

Play first to 3, or whatever you like, with sets supported.

Undo anything

Take back the last dart, even across turns, after a bust or after the winning dart.

Pick up where you left off

The match saves after every dart. Close the app mid-leg and resume from the home screen. The screen stays awake while you play.

Celebrations, sounds & haptics

One hundred and eightyyy.

A 180, a checkout, a nine-darter, a nine-mark turn, a leg, set or match: big moments get an animation, a sound and a haptic. They never slow the game down. Scoring carries on underneath, and a tap skips one.

  • A light tap for each dart, a heavy thud for 180
  • Sounds respect the silent switch and mix with your music
  • VoiceOver announces big moments; Reduce Motion shows a still frame
  • Each one can be switched off in Settings
