Bowling league software for team seasons that run themselves

The full bowling season — fixtures, scorecards, handicaps, standings — without the league secretary's binder. Captains submit cards from their phones, the other team confirms, and Contender OS keeps the season.

What it is

Bowling leagues run on rhythm: same night, same teams, every week. Contender OS books the whole season up front — teams, rosters, and round-robin fixtures — then keeps it week to week. Captains submit the full scorecard from a phone, the opposing team confirms it, handicaps roll off current averages, and game and series points post to the standings automatically.

How the night runs

STEPThe season books itselfTeams, rosters, entering averages, and every weekly fixture are set up in one pass — including bye weeks for odd fields.

STEPCaptains submit the cardAfter the match, a captain or rostered bowler submits the team's full card from a phone, with a photo of the scoresheet as proof.

STEPThe other team confirmsThe opposing team checks the card. Two agreeing cards lock; a photo-backed card stands on its own under the published rules.

STEPStandings keep themselvesGame and series points, handicaps off rolling averages, and the season table update as cards confirm.

What's built in

Whole-season setup — round-robin fixtures for every week, position rounds, and split seasons in one booking.
Phone scorecards — per-bowler, per-game lines submitted by any rostered member, with absent and vacancy fills handled at submit.
Two-team confirmation — cards lock when both sides agree; disputes follow published automatic rules, never a phone call to the secretary.
Handicaps off rolling averages — averages and handicaps stay current as the season bowls.
Public season view — standings, fixtures, and every team's card state, plus a my-team view with each bowler's lines and average trend.
Weekly media kits — the week's results packaged for the center's socials.

Who it's for

Built for bowling centers running house leagues and for league operators who keep seasons across centers — anywhere the standings currently live in a binder, a Facebook photo of a scoresheet, or one volunteer's laptop.
