Where ESPN Fantasy Sports follows professional leagues on a screen, Dart Checker works at the dartboard in your own room. It is a free, ad-free scoreboard for physical dart matches, version 0.9.1, built for Android 5.0 and up. The APK is 4.7 MB and the project is open source under GPL-3.0-only.
Mental arithmetic at the oche
Dart scoring means subtracting three throws from a running total, round after round, often after a drink or two. Dart Checker takes that job over. You enter what you hit, either dart by dart or as the total of all three darts, and the app keeps the score.
The developer says it replaces manual calculation entirely. It works for solo practice as well as for matches with friends, and it supports 1 to 8 players. The one exception is SET/LEG mode, which does not use that player range.
Game modes from 301 to Around the Clock
The game list is broad for an app this small. Single X01 covers 301 and 501, and SET/LEG mode follows the format used in professional play. A free training mode accepts variable scores.
Other modes include Cricket with its Crazy and Cut Throat variants, Halve It in Random or Crazy form, and Around the Clock. Elimination is also offered.
The developer adds options for master, double and single in and out. It provides checkout suggestions for every reasonably possible finish, and unlimited undo for a run of wrong inputs. Random game selection and random player order are included too.
Statistics, languages and the offline promise
Statistics cover about as many matches and players as you like, and they can be exported and imported. That helps if you move to a new phone or want a backup. The app offers a dark theme described as power saving, plus a light one, and four languages: German, English, Spanish and French.
The developer says no internet connection is needed or used beyond the download itself. The app is free and shows no ads.
The package ID is com.DartChecker, and the source is hosted on GitLab.
