Track the price you got.
Log a bet before the game starts. We compare it with an independently captured closing price and show EV against the fair, no-vig close.
Pregame bet logger
Start without an account.
Loading the covered slate…Public launch remains fail-closed until closing coverage is independently verified.
Unsupported: props, parlays, live bets, futures, and bets logged after start. CLV measures price quality, not game wins.
How it works
Price quality, measured honestly.
Closing snapshots are collected once for the full board, not once per user. Same-line comparisons are scored; line moves are shown but excluded from EV statistics.
