Sidelines: Rivalries Tracked

Track every challenge with your crew — from fantasy props to who's buying lunch. Pick a side, settle the score, and finally find out who's been bluffing.

Every friend group has the same arguments.

Who's been carrying the fantasy league? Who swore the Lakers were "definitely losing" last week? Who's hitting the furthest off the tee box? The Sidelines gives you a place to put it on record — and a scoreboard to back it up.

Create a room, drop a bet, pick your side. The app tracks every wager, every win, and every "I told you so" so you don't have to. When the dust settles, settle up in person. We just keep the receipts.

HOW IT WORKS • Create a bet group — public, private, or anywhere in between • Challenge a friend 1-on-1, get the group to pick sides, or open a winner-take-all pool • Log the outcome together, then watch the standings shift in real time • Climb levels, unlock badges, and rack up the kind of bragging rights that actually matter

FEATURES • Three bet formats — 1v1 challenges, group consensus, or winner-take-all pools • Public and private groups — bet with your crew or jump into an open room • Real-time chat in every room, plus DMs with your friends • 40+ badges and achievements for every kind of competitor • Custom level paths — climb the ranks as a Roman general, a pirate, or your own theme • Head-to-head rivalry records for every person you bet against • Open payouts board so nobody forgets who owes who • Push notifications for every challenge, acceptance, and outcome • Sign in with Apple, Google, or email • Light and dark mode

A NOTE ON MONEY Sidelines does not process payments, hold funds, or facilitate real money gambling. We're a scorekeeper, full stop. If you and your friends decide to settle up in person — with a coffee, a beer, a sandwich — that's between you. No cash ever moves through the app.

WHO IT'S FOR • Fantasy league regulars tracking side bets and props • Sports fans making game-day calls with their group chat • Coworkers, roommates, and game-night crews • Anyone who's ever said the words "I bet…"
