Vacaville, California
App designing for competitive games with friends.
Vexcom LLC is a small California software company. We build the apps that run the game night and the golf round: one for bar dart leagues, one for golf groups. Both keep score on everyone's device at once and keep working when the signal drops.
Dart Keeper
Free on the web · iPhone and Android apps comingA scorekeeper built for the board at the bar. Set it on a tablet, tap the scores, and Dart Keeper does the math, the checkouts and the league paperwork.
- 301 with double-in and double-out, 501, Cricket, Fat 6 and more
- League nights with teams, standings and a report e-mailed after every night
- A league can schedule its weekly night, and every board turns on and off by itself
- Player stats built from each player's own turns: averages, highs and 100+ turns
- Works with no signal at the board and catches up when it's back
