Chalk - Sport App

Log every game you watch, rank your season, and call winners before they happen. See how your picks stack up against your friends.

Chalk is a diary for the games you watch.

Log every game — who played, how you watched it, what you thought — and build a season-long record of your fandom. Then back it up: call winners before tip-off and find out whether you actually know ball.

KEEP A GAME DIARY Log any game with a review, a reaction, and how you caught it — live TV, at the venue, a replay, highlights, or at the bar. Your logbook becomes the record of your season.

RANK WHAT YOU WATCHED Compare games head to head. Chalk turns those choices into a personal ranking, so you can settle which game was actually the best one you saw all year.

MAKE YOUR PICKS Swipe through upcoming matchups and call the winner. Track your accuracy, your points, and your day streak as results come in. See what the community picked before you commit.

FOLLOW YOUR FRIENDS Follow other fans to read their logbooks, compare prediction records on a friends leaderboard, and find out who really called it.

NEVER MISS A GAME Browse live and upcoming games across major leagues, and add the ones you care about to your watchlist.

BUILT WITH PRIVACY IN MIND Your logbook is visible only to accounts that follow you. Remove a follower, block an account, or mute someone at any time. Chalk has no ads, no third-party trackers, and never sells your data.

Chalk is for fans who want to remember the games, not just watch them.
