About
Small company, built around the game.
Vexcom LLC designs and builds apps for people who play together: a dart league on a Tuesday night, a foursome on a Saturday morning. We make the scorekeeping disappear so the game is the only thing anyone has to think about.
How we build
Tested where it's played
Dart Keeper runs a real league's nights at the board every week, and Battle Tees is played on the course by real golf groups. Fixes come from what happens there.
Works without signal
Bars and golf courses have bad reception. Both apps keep score with no connection and catch everyone up when the signal comes back.
Your data stays yours
We don't sell, rent or trade personal information. Each app has a plain-English privacy policy and a page for deleting your data.
