## ChallengeFlag Description
ChallengeFlag is the companion app for NFL fans. It sits next to the broadcast, your team's app and your fantasy app, and tells you what is going on and why, in plain language, through all five phases of a game.

1. THE WEEK BEFORE
Open any upcoming game and read who should win and why: the model's win probability and the line side by side, the two best reasons, and the case for the other side. Under it, what each team brings into the game. Record and streak, where its offense and defense rank in the league, scoring form, short weeks and byes, long road trips, the injury report, roster moves from the last week, and the recent history between the two teams. It refreshes three times a day as injury reports, lines and rosters change, so the card you read Wednesday is not the card you read Saturday.

2. KICKOFF
Starters and the depth chart, the injury report as it firms up, weather at the stadium, the projected score and total, and a kickoff reminder for the teams you follow.

3. LIVE
Win probability that moves play by play. Play-by-play with the swing on every snap. Every flag as it is thrown, with what it cost. Score and halftime alerts, so the second screen keeps up with the first.

4. AFTER THE GAME
A recap that reads the way a friend would tell you about the game: what decided it, the key moments and milestones, and what the calls actually cost each side. Rate the calls yourself and see how other fans rated them.

5. BETWEEN GAMES
Your teams all season: roster and depth chart, the transaction wire as moves happen, injuries, coaching staff, schedule, standings and each team's tendencies. Tap any player for a report on role and usage, contract, injury history and performance trend. Pick your favorites and they sit at the top of your schedule.

ALERTS YOU CHOOSE
Kickoff reminders, scores, halftime, challenge flags, high leverage penalties, officiating assignments, and matchup updates when a starting quarterback is ruled out or goes on injured reserve before your game. Each one is a switch in your profile.

ChallengeFlag does not replace the apps you already use. It sits beside them and fills in the why.

Data from Sportradar, live during games and refreshed through the week.
