WeighBook is a fishing tournament management platform designed to help tournament directors run events and anglers find and follow competitions. Its services cover the tournament process from online registration and entry payments to weigh-ins, scoring, results, and payouts. Anglers can search events by name, lake, or club, register, and follow live standings. Directors can manage divisions, teams, multi-day events, season points, side pots, big-fish prizes, and payout calculations.

The platform supports a range of formats and species, including bass, walleye, catfish, crappie, and saltwater tournaments. Its weigh-in tools work offline at the boat ramp and sync results when connectivity returns; kiosk entry, catch-photo submissions, and length-based kayak scoring are also available. WeighBook provides live leaderboards, season standings, and mobile access through iOS and Android apps, as well as a web app. For anglers, the optional Angler Pro service offers tournament pattern insights, bait recommendations, bite forecasts, and lake mapping tools. Pricing is $2 per angler per tournament, with free credits to start and no monthly fees or subscriptions.
