The tools

Twelve ways to read one board.

Every tool works from the same merged prices, so a game means the same thing wherever you look at it.

Markets

Odds screen
Premium

Every book's price for each market, side by side, with the best one marked.
Pick a league and a market, and read across. It's the fastest way to see who's out of line before you open a single app.
Positive EV
Premium

Prices compared with a no-vig consensus of the sharp books.
Old or unconfirmed odds stay visible as calculation-only rows. Stake suggestions require current odds, current references and confirmed EV use.
Arbitrage
Premium

Opposing best prices whose combined chance comes in under 100%.
With stakes worked out for each side. These close quickly, so check the prices at both books before you place anything.
Middles
Premium

Spread and total pairs with a window where both bets win.
Shows the window, the price of each side, and what it costs when the game lands outside it.
Low holds
Premium

Two-way markets ranked by the margin left on the best prices.
Useful for clearing a bonus at the lowest cost, or finding the books that are competing hardest on a market.
Smart money
Premium

How much is on offer at an exchange price, beside the best book on the other side.
It shows depth at a price. It doesn't show trades, who's betting or why, and we don't pretend otherwise.
Line history
Premium

How one book's price moved on one market.
We record main full-game lines. See when a move happened and whether your price was early or late.

DFS props
Premium

Pick'em lines with a fair chance, the break-even chance and the edge between them.
An edge only appears where the app's payout table has been verified. Apps without one are listed with no edge at all.
Slip builder
Premium

The strongest entries for an app, ranked by EV from its own payout table.
Best pick per player, every combination, then ranked. It only works for apps whose payouts we've verified.

Promo converter
Premium

Turn a bonus or a boost into a locked amount, using real hedge prices.
Enter the offer, see what it's worth once hedged, and find a book to hedge it at.
Calculators
Every plan

Prices, staking, arbitrage, middles and more, on numbers you type.
Convert prices, remove hold, size stakes with Kelly, check parlays and work out a hedge.

Bet tracker
Every plan

Your tickets, grading, profit and loss, ROI and closing line value.
Stored only in your browser. Set limits of your own, and it warns when a new ticket goes past one.
