Random forgets. Shuffly remembers. Pick who goes first, split the teams, deal the secret roles. Shuffly keeps track of who went first last time, who got paired together and who sat out, and weights the next result so it evens out. Same squad, same class, same crew every week, and nobody can say it was rigged. One phone, passed around. Works offline, no account. FOR THE SQUAD Even teams for training, a batting order that rotates, a turn in goal for everyone. Match Day tracks every player's minutes during the game, plans the subs before kickoff and adds the minutes up over the season, so equal playing time is something you can show, not just promise. Football, futsal, handball, hockey and basketball. FOR THE CLASS Pick who answers next without landing on the same hand twice. New project groups and reading partners in seconds, and the same two don't end up together every week. FOR THE TABLE Who goes first, who's on whose team, who's the werewolf. Deal secret roles from one phone, roll the dice, and keep score once the game is on. WHY IT REMEMBERS True randomness has no memory. That's why the same kid ends up first three weeks running. Shuffly keeps a history for each group and weights the next pick, pair or team against it, so things spread out over a season instead of repeating by chance. Want a hard rule rather than a nudge? Lucky Pick has a No-repeat toggle that rules the last winner out entirely. WHAT'S INSIDE Pick someone • Finger Pick. Everyone holds a finger on the screen and the countdown picks one. No names, nothing to set up. • Lucky Pick. One winner from your group, or several. Recent winners get weighted down. Split the room • Team Builder. Balanced teams in one tap, each in its own colour. Drag a name to swap it. • Pair Up. Random partners. Odd number? Make a trio or let someone sit out. • Shuffle Line. Batting orders, presentation slots, turn rotations, as a list or a stadium seating chart. Deal the roles • Role Dealer. Secret roles from one phone passed around. Presets for Werewolf, Mafia and others scale to your group size, and you can save your own sets. Run the match • Match Day. Lineups weighted by who has played least, a live clock, subs with one drag, and a Lock Screen view with the score and the next sub. Play and score • Dice. d4 through d20 plus percentile, mixed sizes in one tray. • Darts. X01, Cricket and Around the Clock, with checkout suggestions and bust rules handled. • Minigolf. One shared scorecard and a live leader crown. • Chess Clock. Two to eight players, tap zones big enough for a phone lying flat. GROUPS Save the class, the football gang and the board game crew as separate groups and switch in a tap. Toggle someone off and they sit out until you switch them back on. Each group keeps its own history and stats. PRIVATE BY DESIGN Groups, names, results and scores stay on your device. Anonymous usage analytics are opt-in. The app asks once, and Settings lets you turn it off or delete what's been collected. Names, groups and results are never sent anywhere. Light and dark themes, Dynamic Type and VoiceOver throughout. PRICING Free to download, with 20 sessions you can spend on any mode. No timer, no expiry date. Dice and Finger Pick don't use one up. If the app earns its place, Shuffly Pro removes the session limit for a one-time purchase. No subscription, no ads, Family Sharing included, and modes we add later come with it.
