iPhone
Every league on one screen. Alerts before kickoff. A live draft assistant — then earn deeds, draw familiars, and face the villains beneath the tower.
RosterSage is the companion app for people who take fantasy football seriously — every league on one screen, and a Sage who watches them while you don't.
It doesn't host your leagues. It connects to the ones you already play on Sleeper, ESPN, and Yahoo, unifies them, and does the work a chat window can't: it watches your rosters and pings you before it matters.
EVERY LEAGUE, ONE SCREEN
A unified dashboard — matchups, projections, and what needs your attention across all your leagues at once.
PROACTIVE ALERTS (THE WHOLE POINT)
• A starter ruled Out or Doubtful — pushed ~90 minutes before kickoff, while you can still act.
• Breaking player news that touches your roster.
• Lineup-health nudges, Tuesday waiver intel, and a Friday game-plan briefing.
A REAL DRAFT ASSISTANT
Live draft sync on Sleeper, ESPN, and Yahoo, plus mock drafts — snake and auction — against bots that draft like people do. A purpose-built board, not a chat window.
DECISION TOOLS
Start/sit, a lineup optimizer, a trade analyzer with fair-value math, and a waiver / free-agent finder — all reading your actual rosters and league scoring.
A SEASON THAT REMEMBERS YOU
Most fantasy tools forget you the moment you close them. This one keeps a record — and that record is the app's whole personality.
• The Spire. Your tower, floor by floor. Every call you made under the Sage's watch is inscribed here: deeds for the drafts you nailed, the disasters you survived, and the weeks you had no business winning.
• Familiars. Earn enough and something comes to roost. The Wisp arrives first. The Owl belongs to a studied draft board, the Raven to the seasons that break your heart. The Dragon is the apex — and the Phoenix is the rarest story in the app.
• The Undercroft. Beneath the tower, villains hold the draft rooms, each cheating in one stated way. The Warlord's court takes running backs two rounds early. The Trickster shuffles the board and takes your rankings away. The Miser bids up whatever you need. Clear a door's published bar and its sigil is yours. Three doors are open. The rest are sealed.
• The Oath at the Board. When your draft ends, swear to something. The Sage writes it down, and the season decides whether you were right.
None of it changes the advice. The Sage tells you the same thing either way — the tower is just what's left behind when the season is over.
RosterSage is read-only: it never touches your lineups. It just makes sure you never miss the move that wins the week.
Connect a league in under a minute. Bring your season into focus.
