Draft night moves fast. DraftMatrix keeps you ahead of it. DraftMatrix is a live draft board built around expert tier rankings. Instead of a flat list, players are grouped into tiers so you can see position scarcity at a glance — and when a tier is about to run dry, the board warns you before it's too late. TRACK THE DRAFT • Tap a player when another team drafts them — one tap, crossed out • Star players onto your roster; undo any mistap instantly • Pick clock tracks the round, overall pick, and how many picks until your turn (snake or linear) • Keepers supported — marked drafted without advancing the pick clock KNOW WHO'S LEFT • Tier counters turn orange when a tier runs low and red on the last player • Filter by position, search every list, or hide drafted players • Bookmark sleepers before the draft and filter the board to your targets • Bye weeks and average draft position on every player AI SUGGESTIONS, FULLY PRIVATE Stuck between two players? Apple Intelligence analyzes your roster and the remaining pool using value-based drafting logic and recommends a pick with a plain-English rationale — entirely on your device. Nothing about your draft ever leaves your iPad or iPhone. (Requires a device with Apple Intelligence.) MADE FOR DRAFT DAY • Multiple drafts with independent boards — run two leagues side by side • Draft state syncs between your devices through your personal iCloud • Import your own rankings from a CSV • Works offline: cached rankings and a built-in snapshot keep the board alive • Share your finished roster with one tap Tier rankings from publicly published borischen.co data; ADP and bye weeks from Fantasy Football Calculator. No account, no ads, no tracking, no data collected.
