Dozens of divisions. Short games. One packed Saturday.
Flag football leagues run many divisions in quick game slots across fields split into smaller fields. MySideline fits every game into your weekend and keeps each division on the fields made for it.
Set up for the way flag football runs
MySideline's field rules, time slots, and scheduling constraints are set up around how a flag football league actually plays.
Many grade and age divisions, short game slots
Time slots sized for short flag games let you run many grade and age divisions through the same fields in a day.
Boys, girls, co-ed and adult in one league
Run every kind of division in a single league, each with its own field rules and round robin.
One big field, several small fields
Set up each small field on a large field as its own field, and MySideline schedules each one on its own.
Youngest players at the right venues
Field rules keep your youngest divisions at the venues suited to them.
High-volume weekend scheduling
No venue is opened for a single game, even on your busiest weekends.

Preview.
Referee assignment
Referees see open games and largely self-assign from a texted link, within rules you set for each ref.
HorizonWebRef integration
The schedule written straight into HorizonWebRef, so assignors stop re-entering games, with ref changes kept in sync.
Registration and payments
Player and team registration with payment collection, custom sign-up links for each season or tournament, and players placed into the right age group automatically.
Scores, standings and stats
Scores entered from a texted link at the final whistle, or by coaches and admins. Public standings pages that update as scores come in, plus team and player stats.
Text message notifications
Texts to opted-in coaches and families when a game changes, and reminders ahead of games.
Crossover games between divisions
Games between teams from different divisions, built into the schedule.
