Your week as a range, not a guess

- Your likely scoresWhere your lineup lands most weeks, from a bust week to a boom week.
- Your opponent'sTheir lineup, scored the same way with the same lines.
- Where it's decidedWhere the curves cross. The more of yours sits to the right of theirs, the better your odds.

- Your win chanceHow often you come out ahead across all 4,000 games.
Built for the whole season
Maxing out this week matters. A roster that keeps winning matters more. The same lines that set your lineup show which players are worth more than their name, who belongs on your bench, and who should be on your roster instead.

Questions
Short answers. The details are one tap away in the app.
Where do the numbers come from?
Sportsbook player props (passing yards and touchdowns, rushing yards, receptions, receiving yards and anytime touchdowns) and each game's spread and total. Those become a range of fantasy points per player, scored with your league's settings.
Do I need to give it my Sleeper password?
No. It reads your league from Sleeper's public data with just your username. It can't change your lineup or anything else.
What scoring does it use?
Your league's own settings from Sleeper. Before you connect a league, everything is scored full PPR.
What do bust and boom mean?
Bust is the score a player falls below about one week in five. Boom is the score he beats about one week in five. The projection sits in between.
When do the numbers update?
Player props are pulled Thursday mornings. On Sundays, injury news triggers a re-check before the early and late games, around 8:00 and 11:45 AM Eastern. Live scores fill in as games are played.
What about kickers and defenses?
They use Sleeper's projection with a typical range for now, since there are no props for them.
Is this a betting app?
No. The lines are only used as information about what's likely to happen. There's nothing to bet on here.
