Foldling is a virtual pet application on iPhone, made specifically for the iPhone Duo. The main character is Kit, a little paper fox living right in the crease of the device.

Foldling gives you a cute little break: take care of Kit for a few minutes and then return to work or go to sleep, instead of endlessly scrolling social media.

Main Features

• Fold the device into a V shape, and the crease becomes a small valley. Drop seeds, and they will roll to Kit.
• Play ball with Kit and decorate Kit's house.
• Set a 25-minute focus timer, starting right from the widget. Kit folds origami cranes while you work.
• Soothing sounds, gradually dimming lights, and gentle alarms.
• Home screen widget to visit Kit anytime.

Who Should Use It

iPhone Duo users who want to take advantage of the foldable design, those who need extra motivation to focus, and those who want to relax before sleep.

How to Get Started

Download for free on the App Store, for use on iPhone running iOS 26 or higher. You can still play without an iPhone Duo, just with different controls. No ads. The Foldling Plus package (one-time purchase, no subscription) unlocks additional decorations, sounds, widget styles, and synchronization across devices.

What Makes It Different

Most virtual pet apps only involve tapping and swiping. Foldling uses the crease of the iPhone Duo as part of the game.
