ChallengeFlag: Pro & College

ChallengeFlag is the companion app for football fans, pro and college. 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.

PRO AND COLLEGE
One switch on the schedule. Every pro game and every FBS college game gets the same companion: the same five phases, the same alerts, the same favorites, each league with its own schedule, standings and profile tab.

1. THE WEEK BEFORE
Open any upcoming game and read who should win and why, with how ChallengeFlag's picks have done this season: 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, 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, and on pro games an expected points chart beside it that shows which team is playing better, not just who is winning. Play-by-play with the swing and the expected points on every snap. Every flag as it is thrown, with what it cost and, at a glance, what fans thought of the call. A turnover bar and a red zone chip on the Game tab. Score and halftime alerts, and a live score chip in the status bar on Android, 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 what the calls actually cost each side. Milestones, grouped by team: every pre-game line against what the player actually did. 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. A quarterback board ranks every passer by expected points added per dropback, with completion percentage over expected beside it, and each team page carries its offense and defense EPA with league ranks. Search the college schedule by school. Pick your favorites, pro and college, and they sit at the top of your schedule.

OFFICIATING
Every pro officiating crew's penalty profile. In college, crews are assigned by conference, so each game carries the assigning conference's profile against the FBS average.

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, for each league.

College lines are ChallengeFlag projections, labeled as such. ChallengeFlag does not take or place bets.

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

Data live during games and refreshed through the week.
