Yapple: Wrong Number

What happened to Dave? Find out on a chunky flip phone strangers call by mistake, with 1,000+ words to dial. Open to answer, snap shut to hang up. Made for iPhone Duo.

Somebody's calling. You don't know who. They don't know you either.

Yapple turns your iPhone into a chunky, plasticky, early-2000s flip phone, and strangers keep calling it by mistake. Up to three times a day, it rings. Pick up and someone's already talking: a grandpa who remembers when phones were a rock, a horse clinic chasing your horse's warranty, a pirate who wants to know where you buried it, your mom asking if you've eaten, a goat. Every caller has a voice of their own, down a crackly line, with subtitles. You never say a word.

THERE'S A MYSTERY TO SOLVE Some of them keep calling back, and they're all looking for the same man. This used to be his number. Listen closely: the clues are in the calls. Work out who to ring, dial them, and find out what happened to him.

DIAL A WORD The keypad works. Spell a word on the letters and press green, and 1,000 words pick up: animals, things and characters. GOAT. PIZZA. ZEUS. The SUN, but only at night. 666, where Mom shares a line with the Devil. 911 is open weekdays, nine to five.

MADE FOR IPHONE DUO Folded, the little outside screen shows who's calling and the whole thing buzzes. Open it to answer: the caller starts talking the moment the hinge cracks open. Snap it shut to hang up. Open, the wide inner screen puts their face beside their name. On every other iPhone it's the phone flipped open in your hand, and the green and red keys do the hinge's job.

YOURS, FOREVER Pick your phone's colour on the first day: cream, translucent purple, lime green, hot pink, baby blue or grey. You can never change it. Then it wears in, call by call: scuffs, grubby keys, a creaky hinge, and near the end a cracked screen and a line of dead pixels. Even its icon on your home screen turns your colour.

Calls ring as notifications, so it rings even when the app is closed. No accounts, nothing to sign up for. Free to start, with one small banner ad: one purchase unlocks the whole story and removes the ad for good.
