RUMPUS: Party Games & Voice

Four party toys in one app: live voice effects, couples and party decks, beat-synced lights, and a phone-in-a-glass speaker trick. All offline.

Your phone is the party trick.

RUMPUS turns one iPhone into four party toys — and every one of them works with no signal, no account, and nothing to sign up for.

FUNNYMIC — YOUR VOICE, RIDICULOUS Talk or sing through live voice effects: chipmunk, demon, robot, broken autotune and stadium reverb. Hand someone the phone and they are laughing at themselves within five seconds. It runs over whatever music the room is already playing.

CHALLENGE — TRUTHS, DARES & DATE NIGHT Two free decks to start: a couples deck that eases from sweet questions into flirtation, and a group truth-or-dare deck that is funny without making anyone squirm. Before you play, each person privately picks how far they are comfortable going, and the game runs at the gentler of the two choices. Skip any card with zero fuss and no penalty. Press and hold to ban a card forever.

STROBE — LIGHTS ON THE BEAT RUMPUS listens to your music and flashes the screen and torch in time with it. No clear beat in a loud room? Tap the tempo yourself. Flash rate is capped for safety, and thermal and battery guards keep your phone alive for the rest of the night.

AMPLIFY — PHONE IN A GLASS No speaker? Stand the phone in an empty glass, a bowl, a mug or a bottle. We show you exactly how to place it for the loudest result.

WHAT HAPPENS AT THE PARTY STAYS ON THE PHONE Microphone audio is processed on your device and is never recorded, stored or uploaded. Your answers are never captured. Player names are deleted a few hours after you stop playing. There is no account to create and nothing to log into.

ONE-TIME PURCHASE Play free with two decks and five voices. Unlock everything with a single purchase — no subscription, ever.

Rated 17+. The Challenge decks contain mature and suggestive themes.
