Track your bets against the board
Every tracker tells you your own numbers. This one tells you whether they're any good — because it sits next to a model that grades every call it makes in public, wins and losses alike.
Your book is one tap away.
Signing out only forgets you on this device. Your book stays, and your link still opens it.
New or returning: enter your email and we'll send you a sign-in link. Free permanently for early accounts — including this one.
Check your inbox. We sent a sign-in link to . It works once, within 30 minutes, on the device you open it on. If it isn't there in a minute, check spam or promotions.
Your tracker is ready, and this device will remember you. Save this link too — it opens your book on any other device, and it's the only way back if this one forgets you. We can't send it to you again.
What you get
Tap a game on the board and it lands in your book, graded automatically when the game goes final. Log bets from anywhere else by hand — including books and markets we don't cover.
Game Cards and Prop Cards open the moment you sign up. Game Cards put every game on one tile with the day's surest pick and an upset watch. Prop Cards rank every FanDuel player prop from most likely to least, with each player's recent games against tonight's line. Both are graded in public.
Units and dollars, because they disagree
Most trackers show one or the other. Keeping both is the point, and the gap between them is usually the most useful thing on the page.
A real book from this tracker recently read −3.84 units and +$87 at the same time. Both numbers were right. One winner had been staked roughly ten times the size of the losses — so the bankroll was up while the betting was down. Had that single bet lost, the same record would show about −$100.
That's not a rounding error, it's the whole game: sizing decides outcomes at least as much as picking does, and a unit-only tracker will never show it to you.
Graded against something honest
The board calls every game, publishes a confidence number, and grades itself in the open — currently landing about a point under its own claim across hundreds of games. Your record sits beside that, on the same games, so "am I any good?" has an actual reference point instead of a feeling.
Free — and it stays free for everyone who joins now. If a paid tier ever arrives, early accounts keep everything they already have. No card, no app to install. We store the address you enter and the bets you log — nothing else. Read why we build it this way, or start with the Lab.
