About this app
Flex Fantasy is an AI co-pilot for your fantasy football team. Connect your Sleeper, ESPN or Yahoo league and Flex reads your real roster, your league's scoring settings and the rest of your schedule, then tells you what to actually do about it.
Every recommendation leads with the verdict, not a wall of numbers.
WHAT FLEX DOES
Team Rating
A single 0-100 score showing how your roster stacks up against the best possible team in your league for the rest of the season. Tap in to see exactly which positions are carrying you and which ones are costing you wins.
AI trade suggestions
Flex scans every other roster in your league for trades that make both sides better, then shows you what each one does to your rating, your record, your playoff odds and your title odds. Build your own trade in the evaluator and get the same read before you send it.
Waiver wire advice
Real pickup recommendations based on who is actually available in your league, what it would cost you in FAAB or waiver priority, and how much the move is worth to your season.
Start/sit and lineup optimizer
The optimal lineup for this week and for the rest of the season, with the reasoning behind each call and clear flags on the decisions that are genuinely close.
Rest-of-season outlook
Projected finish, playoff odds and championship odds, plus a week-by-week look at your remaining matchups so you know which weeks you need to win.
Multi-league support
Sync all your leagues and switch between them instantly.
BUILT FOR REAL LEAGUES
Flex reads your actual league settings, including roster slots like FLEX and superflex, custom scoring, and league size. Advice built for a 10-team half-PPR league is not the advice you need in a 12-team superflex league, and Flex knows the difference.
SUPPORTED PLATFORMS
Sleeper, ESPN and Yahoo.
GETTING STARTED
No account needed to try it. Pick your platform, connect a league and Flex has your team analyzed in seconds.
Flex Fantasy is not affiliated with or endorsed by the NFL, Sleeper, ESPN or Yahoo.
