Questions, answered plainly.

LINE is a sports prediction and betting intelligence app. Its engine, CMOS, calculates win probabilities and projected scores for NFL and college games. LINE sets them beside the odds, shows you the edge, and grades every official pick on the LINE Report Card.

CMOS (Computational Modeling & Outcome Simulation) is LINE’s proprietary prediction engine. It analyzes historical results, team and player performance, matchup tendencies, behavioral tendencies and situational factors like home field and rest to calculate the probability of each outcome.

No. LINE doesn’t take bets, hold money, pay out winnings or link you to a sportsbook. The bet tracker just records bets you place elsewhere.

LINE gives you better information, not promised results: no plan guarantees winning bets or profit. In LINE’s 2020–2025 backtest, the sportsbook favorite picked winners more often than LINE did. Use LINE to inform your bets, never as a reason to bet more.

Anyone 21 or older. LINE is for information and entertainment; check the laws where you live before you bet anywhere.

One of the day’s biggest edges: a market where LINE’s probability beats the probability the odds imply by the most. Every game day, the app ranks them across the sports in your plan.

For negative American odds, divide the odds by the odds plus 100 (−110 → 110 ÷ 210 = 52.4%). For positive odds, divide 100 by the odds plus 100 (+150 → 100 ÷ 250 = 40.0%). That’s the win rate the price needs to break even, including the sportsbook’s margin.

Edge is the gap between LINE’s probability and the implied probability, in percentage points (55.0% − 52.4% = +2.6 points). Expected value is the average return per dollar staked if LINE’s probability is right, using the actual payout of the price (at −110, 0.550 × 0.909 − 0.450 = +5.0%).

Not every time. A positive expected value is about the long run, not one game, and any forecast can miss. LINE’s models haven’t yet proven a long-run edge over sportsbooks, and no plan guarantees winning bets or profit.

LINE’s graded record of official picks: how many winners it called, out of how many games, and over what dates. Only picks locked before kickoff count, every final game is included, and backtests are kept separate.

Each official NFL pick is saved at least 30 minutes before kickoff with a server timestamp and a SHA-256 fingerprint. Changing a saved pick would change its fingerprint. Misses stay on the Report Card.

Official NFL picks come from frozen CMOS models with locked pregame logs, and they’re the only picks on the Report Card. College forecasts are research: saved before each game and graded, but newer and labeled research.

Backtests re-run the frozen models on past games using only what was known before each kickoff. They help judge a model, but they never count on the Report Card.

NFL: live; College Football: beta; NBA: in development; College Basketball: beta; MLB: planned; College Baseball: planned; NHL: in development; Soccer: planned; Tennis: planned; Golf: planned; MMA & Boxing: planned; Horse Racing: in development; High School Football: planned; Greyhound Racing: planned. Live sports have official predictions; beta sports have research forecasts; sports in development or planned have no games, odds or picks until LINE has a licensed data source.

No. Previews on this website and the demo use fictional teams, unnamed example sportsbooks and example numbers, all labeled. Real games, prices and LINE’s numbers are in the app.

Ask Ace is LINE’s AI sports assistant. It’s in development and not yet in the app. Ask about matchups, prices and your teams in plain English; Ace answers from LINE’s data and tells you when it doesn’t have something.

Not yet. An NFL rushing-yards model is being tested, and prop prices aren’t connected. Player projections go live once both are in place.

Monthly: $5.99 for your first sport, $1.99 for each additional sport, or $14.99 for All Sports, renewing each month until you cancel. Yearly, as a Founding Member, paid once for 12 months: $71.88 for your first sport ($5.99 a month equivalent), $23.88 for each additional sport ($1.99 a month), or $179.88 for All Sports ($14.99 a month). A set of sports never costs more than All Sports. The introductory price applies to your first year.

Monthly plans renew each month until you cancel. The Founding Member year doesn’t renew automatically: regular yearly pricing hasn’t been set, and LINE will ask before any future charge. Your sports and your renewal date are under Account › Subscription.

Yes. Adding a sport during your year costs the difference for the time left until your renewal date, and you see the amount before you pay. Moving up to All Sports works the same way.

Not on its own. Only sports with licensed data can be chosen one by one. All Sports includes each new sport as it launches during your year.

Schedules, scores, live scores (up to 5 games in progress per sport), the full official and research record, and, with a free account, LINE’s pick for 3 games a day.

Cancel a monthly plan under Account › Subscription before your next billing date. The Founding Member year is paid up front and doesn’t renew automatically, so there’s nothing to cancel to avoid a future charge. Your sports stay open until your renewal date. For billing questions, see Account › Subscription or contact support.

Sign in at app.lineresults.com with your email; LINE sends a one-time code, no password. Your plan, billing and cancellation are under Account › Subscription.

LINE is invitation-only during the beta. Email [email protected] to ask for an invitation. Subscriptions run in Stripe test mode during the beta, so no real payments are taken.
