GRABBLE: Color Hunt

The app names a colour; you race to aim your camera at something that colour in the real world. Scored on device, always with the reason. Solo or pass-and-play.

GRABBLE turns the room around you into a colour scavenger hunt.

The app calls out a colour. You race to point your camera at something that colour in the real world — a red mug, a green plant, a blue jacket. An on-device model scores your match out of 10, and it always tells you why: "dead-on red", "a shade towards orange", "a little too dark". No blind numbers, no arguing with the app.

Speed counts too. The faster you find it, the bigger your bonus. Accuracy × speed — that's the whole game.

THREE WAYS TO PLAY • Solo — beat your own score, round after round. • Pass & Play — one phone, take turns. Everyone gets their own colour from a matched difficulty band, so it stays fair. • Nearby (coming soon) — several phones, one room.

WHY IT FEELS FAIR Every score comes with its reason, a side-by-side of what was asked versus what you showed, and the exact patch it measured. You can always see why you got the number you got.

100% ON YOUR DEVICE No account. No ads. No data collected. No tracking. Camera frames are analysed on your phone and never leave it — nothing is uploaded, and it all works offline.

Eleven colours, rounds and a timer you set yourself, big glanceable scores, satisfying haptics, and a clean design that stays out of the way of the real world.

Grab your phone. Find the colour first.
