ChallengeFlag: NFL Companion

Every game, explained. See why it was won, which unit swung it, the plays that decided it, and how our calls held up. Tap any stat for who did what.

Every NFL game has a third team on the field. Challenge Flag Ratings covers that one.

REFEREE CREW INTELLIGENCE See who is officiating your game before kickoff and what that crew tends to call. Home and away bias, penalties and EPA per game for the referee and the full crew, each official's top calls against the league average, and how this crew has flagged each of the two teams.

LIVE GAMES Score, clock and quarter for your favorite teams' games, on the lock screen and in the notification shade. On Android 16 it shows as a live chip in the status bar.

EVERY FLAG, RATED Play-by-play with every penalty in context. Watch the clip, rate the call, and see how the community rated it. High-leverage flags and coach's challenges come to you as alerts.

WIN PROBABILITY A live win probability graph for every game, plus pregame projections, over/under and the line.

YOUR TEAMS Pick your favorites and the schedule puts their games first, with projections at a glance. Team pages, standings, injuries and props for every matchup.

ALERTS YOU CHOOSE Kickoff, score changes, halftime, challenge flags, high-leverage penalties and crew announcements, each one on its own switch.

Built for fans who want to know what the officiating means for their team, before the game and during it.
