About

WhosFirst

Features
Read full description

WhosFirst settles the oldest argument at game night: who goes first? Instead of rock-paper-scissors or the "youngest player starts" rule, hand the decision to a fair, delightful picker — then let WhosFirst remember your crew and keep score across every session. WHY WHOSFIRST IS DIFFERENT Most picker apps forget everything the moment you close them. WhosFirst is built for the people you actually play with. Save your regular groups — "Tuesday Game Night," "Family," "The D&D Table" — and every pick is logged, so over time you can see who's been luckiest, who's on a streak, and who never seems to go first. - Group memory — save named player groups instead of retyping names every week - Long-term stats — selection counts, win streaks, and a luck score per player across your whole history - Eight ways to decide — pick the mechanic that fits the table EIGHT PICKER MECHANICS - Spin Wheel — a physics-based wheel with satisfying clicks and haptics - Dice Roll — real 3D dice tumble across the felt; highest roll wins, ties re-roll - Finger Touch — everyone holds a finger down and one is randomly crowned - Lightning Strike — a storm gathers and a bolt picks the last one standing - Slot Machine — spin the reels for a three-in-a-row winner - Balloon Pop — balloons race to the finish and the winner bursts - Card Flip — high card wins in a quick draw - Rocket Launch — rockets blast off in a photo-finish race BUILT FOR REAL GAME NIGHTS - Remove-once-selected mode — keep picking until everyone has had a turn - Works fully offline — no account, no sign-up - Private by design — your groups and stats sync across your own devices via iCloud - No ads. No subscriptions. FREE & PREMIUM Start free with the spin wheel. Unlock WhosFirst Premium once — a single purchase, never a subscription — to open every picker mechanic and full group statistics. Grab a game, gather your people, and let WhosFirst decide who's first.
