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, 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. ChallengeFlag is an independent app and is not affiliated with, endorsed by or sponsored by any league, conference, team or school. Team and school names are used only to identify the games being described. Data from Sportradar, live during games and refreshed through the week. ## Key features - Pro and college football game companion - Pre-game analysis and predictions - Live win probability and play-by-play - Officiating penalty profiles - Team and player transaction tracking - Post-game recaps and call ratings ## Is ChallengeFlag safe?

Finally! *2026-10-01* This app has everything I could possibly need to know about everything NFL. I keep discovering new stats that give me an edge on understanding the game and win probabilities. Unfortunately my team isn’t looking good-but I can’t blame the app for that. It’s all on Mike McDaniel! **Developer response:** Bolt Up. Watching one game live and keeping two more running in the app is exactly the setup it was built for, and "perfect companion at game time" is the phrase I will keep. Thank you for the review. If a game ever lags or an update looks off, tell me and I will check it. Matt, ChallengeFlag ### 5/5 — I leave it open during the game now *2026-09-30* I used to flip between the score app and Twitter. This one stays on. Before the game I can see who’s hurt and who’s working the game. During it, every play shows up with the score and that little chart that moves when something big happens. When they throw a flag it tells you if it actually wrecked the drive or just felt like it. After the game I finally understand why we lost instead of just staring at 24–20. ### 5/5 — Finally shows which play actually ended it *2026-09-29* Sometimes it’s a pick. Sometimes it’s a missed kick. Sometimes it’s a flag. This app points at that play instead of making you scroll the whole box score. I sent my dad the screen after the Chargers game and he got it immediately. That’s rare for a football app. ### 5/5 — It’s all here *2026-09-27* Only App with all the stats and ability to understand the referee impact on a game. **Developer response:** I'm glad you like all the data. We work hard to provide meaningful analysis! - Challenge Flag, Matt Mason ### 5/5 — Cool app! *2026-09-27* All the information you need in one place! **Developer response:** I'm glad you like all the data. We work hard to provide meaningful analysis! - Challenge Flag, Matt Mason ## Frequently asked questions about ChallengeFlag ### What is ChallengeFlag?

Expected points added (EPA) tells you who is playing better. Every pro game page now has an EPA chart beside the win probability graph: each offense's EPA added up play by play, in its team's colors. Drag across it to see each play and what it was worth; tap to jump the play-by-play there. The info button explains how a team can be ahead on one chart and behind on the other. EPA shows up across the app. Every play in the play-by-play carries its EPA under the win probability swing. Every penalty card shows what the flag cost in EPA. The recap's "What the calls cost" adds an EPA column. The starters card shows each quarterback's season EPA per dropback and completion percentage over expected (CPOE). QUARTERBACK BOARD Standings has a new QB EPA tab: every quarterback ranked by EPA per dropback, with CPOE beside it. Quarterbacks with enough dropbacks rank; the rest list below. Tap a row for the player report, or the team for its page. TEAM PAGES AND PLAYER REPORTS Team pages get an EPA card: offense and defense EPA per play, for the season and the last four games, each with its league rank, plus the team's quarterbacks. Player reports add an efficiency section with EPA per dropback, CPOE and weekly sparklines, show each player's real experience, and list this season's coaches. THE FANS' VERDICT AT A GLANCE Every penalty in the list now shows what fans thought of the call as a face, from a perfect whistle to a blown call, with how many rated it. Your own rating shows your face and the call's name. COLLEGE Search the college schedule by school: type KEN and Kentucky's game comes up. Abbreviations work too. Overtime scores land in the OT column of the box score instead of the first quarter, and the total is always the game's own. WHO SHOULD WIN The matchup card now shows how ChallengeFlag's picks have done this season, once there are enough games to count. The pick also takes the line into account. FIXES An injury alert names the quarterback. Opening a team page from an alert waits for sign-in instead of saying the team was not found, and offers a retry. The college schedule waits for the full week before saying no games match. ### 2.1.8 — 2026-10-09 COLLEGE FOOTBALL Everything ChallengeFlag does for a pro game, it now does for FBS college games. Tap the league pill on the schedule to switch between Pro and College. The app reopens on whichever league you left it on. The college schedule works like the pro one: the week header, your teams on top, day pills between the cards. Standings by conference, plus the AP Top 25. Open any college game and get the same five phases. Before kickoff, who should win and why, and what each team brings in. At kickoff, the starters built from the season's stat lines. Live, win probability that moves play by play, the play-by-play with the swing on every snap, and every flag with what it cost. After, a recap and the Milestones: each player's projected line against what he actually did, filled in from the plays as they land. College lines are ChallengeFlag projections, labeled as such, and never a betting line. College officiating is assigned by conference, so each game carries the assigning conference's penalty profile against the FBS average on the Refs tab and in Game Intel. Every college school has a team page: schedule with results, roster by position with each player's card and game-log charts, coaches and ratings. Tap a school's name anywhere to open it. Pick college favorites by conference in your profile. College kickoff reminders, score, halftime and flag alerts have their own switches under a College tab, next to Pro. PRO GAME DAY A turnover bar under the box score. A red zone chip while the offense is inside the 20, with that team's touchdown rate. The coin toss slot becomes a message board once the game starts. At a quarter break, a line when tonight's quarter breaks the season's pattern. MILESTONES Milestones ride the right edge of a live or finished game as a pull-out, for both leagues, and group every line under its team. Each line fills from the plays as they land. ALERTS Score alerts fold into the live card while you are on that game and post as notifications otherwise. Injury alerts open the team page on its Injuries tab. SIGN-IN Sign-in checks your email and password before it sends anything and tells you plainly what is missing. ### 2.1.6 — 2026-09-30 This release makes ChallengeFlag a companion for the whole life of a game, not just the three hours it is on. THE WEEK BEFORE A new card on every upcoming game's Intel tab tells you 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 in: record and streak, where its offense and defense rank in the league, scoring form, short weeks and byes, 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 the week changes. KICKOFF Team records in the game header and box score. Standings show the team code. LIVE Notifications arrive once, not twice. AFTER THE GAME Recaps now read the way a friend would tell you about the game: what decided it, what the calls cost, and what to take from it. BETWEEN GAMES Turn on Matchup Updates in your profile for one alert when a starting quarterback is ruled out, a quarterback move lands, or a player goes on injured reserve before a game your team plays. ALSO A password checklist while you register. Logout is labeled and asks first. Tab labels no longer truncate. A new app icon. ### 2.1.5 — 2026-09-19 Game recaps, rebuilt. • "How it went": a one-line headline on why the game was won, a side-by-side stat table, and the key factors behind the result. • Offense, defense and special teams cards with two-team sparklines. Tap a unit to see who did what. • A glossary for every stat abbreviation, pulled out from the right edge of the Recap tab. • "Plays that decided it" now measures each play's true swing in win probability. • Renamed the prediction review to "How our predictions panned out". • Fixed roster cutdown moves showing under Regular Season on the Moves tab. ### 2.1.4 — 2026-09-16 • Live game score on your lock screen for your favorite teams • Referee crew intelligence on every game with an assigned crew • Favorites show the projection and line for each game • Team names in score and halftime alerts • Fixes: notification taps open the right game, sharing right after launch, sign-in on a new phone ## Apps similar to ChallengeFlag | App | Rating | Price | Category | | --- | --- | --- | --- | | [StreamCaddy](https://appshunter.io/ios/app/streamcaddy/id6792604444) | 5.0 (2) | Free | Sports | | [Paddle Up: Pickleball AI Coach](https://appshunter.io/ios/app/paddle-up-pickleball-ai-coach/id6809176237) | 4.8 (5) | Free | Sports | | [Stanford Card4Life](https://appshunter.io/ios/app/stanford-card4life/id1560274278) | 4.3 (4) | Free | Sports | | [Arena: Paper Trade Sports](https://appshunter.io/ios/app/arena-paper-trade-sports/id6767367078) | 5.0 (34) | Free | Sports | | [StatSide Sports](https://appshunter.io/ios/app/statside-sports/id6793266645) | 5.0 (3) | Free | Sports | | [Briarwood Golf Club - MT](https://appshunter.io/ios/app/briarwood-golf-club-mt/id1592566673) | 4.7 (3) | Free | Sports | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
