Your throw. Your score. Zero arithmetic. DoubleTop tracks everything so you don't have to. Tap the board where each dart landed and your remaining score updates on the spot. No adding up. No subtracting in your head. No arguing over who's on what. When you're within checkout range, the app tells you exactly what to aim for — three darts, two darts, or one. It knows the routes. Set up a game in seconds: pick 501 or 301, name your players, and throw. DoubleTop handles the double-out rules, catches busts before you can miscalculate them, and tracks legs, sets, and full matches automatically. Playing in teams? Add up to four players per side with proper rotation — it keeps track of whose turn it is so you don't have to shout across the pub. At the end of a match, the stats tell the story: three-dart average, 180s, ton-plus finishes, highest checkout, checkout percentage. The whole thing runs on your device. No account to create, no internet needed, no ads to sit through. Just darts.
