Stuck on a bogey number? See exactly what to throw to leave your favourite double for the next visit.
Drill all 162 checkouts. Filter doubles, 51–100 or 101+, build custom decks — misses come back around until they stick.
Your preferred outs ranked first, five themes, a home-screen widget — and all of it 100% offline. No account, no ads.
The whole calculator on your wrist — routes, leave planner, flash cards and a game tracker. It works on its own, phone in your bag.
Tap the mic and say it — “forty seven”, “one seventy”, “double top”. The checkout appears. On iPhone and Apple Watch.
Start at 501, tap each dart on a proper scorer keypad, and it tracks the leg. SHOW ME gives the route for the darts you have left — not a finish you can’t throw.
Large Numbers fills the screen. Read out loud speaks every checkout — “fifty seven. Treble seventeen, double three.” Free for everyone.
Every score from 2 to 170, instant. Trebles, doubles, singles — the optimal dart-by-dart path is one tap away.

The full calculator, on the watch: routes, the leave planner, flash cards and a game tracker. Tap the mic and say your score, or roll the crown to dial it in. Flip on Large Numbers and Read out loud in the menu and it fills the screen and calls the route back to you — free for everyone.
