Kit is a little paper fox who lives in your phone. Feed and play, focus while Kit folds a paper crane, and fall asleep together to rain and soft piano. On iPhone Duo, the fold is Kit's valley: fold the phone into a V and seeds roll into the crease. Feed Kit in the fold. Drop a seed and watch it roll down the valley to Kit. On other iPhones the crease is fixed and you tilt the phone. Play ball with Kit. Shake the phone or tap the ball, and Kit runs after it. Goodnight, Kit. Fall asleep to rain and slow piano, or soft noise, while the night sky in Kit's window follows what you hear and the lamp slowly dims. On iPhone Duo, just close it and Kit curls up on the outer screen. Nothing bad happens while you are gone: Kit's needs never drop below a gentle floor, Kit never runs away, and one missed day a week is forgiven. Care builds a cosy home. Every seed, every game and every visit grows your bond, and new decor unlocks as your bond grows. Decorate Kit's house: put pieces in the big house or take them out. Focus with Kit. Start a session and Kit folds a paper crane while you work or study. Pick a timer, Pomodoro rounds or open-ended Flow. Each finished crane goes on your shelf. Stop early and nothing is lost: Kit keeps the half-folded crane for later. Share Kit's certificate. Make a Fold Card: a paper certificate of your bond with Kit, with a QR code friends can scan. Made on iPhone Duo, it carries your fold angle. A WHOLE LITTLE WORLD • The valley, where seeds roll to Kit • The big house, where your decor goes • The bedroom, for naps, sleep sounds and the night • Hold a finger on Kit to hear a purr • Small and medium Home Screen widgets show how Kit is doing FOCUS, YOUR WAY • Timer and Pomodoro rounds of 15 or 25 minutes, or Flow with no time limit • Your session on the Lock Screen and in the Dynamic Island, with Pause and End • Start from a widget, Control Center, the Action Button or Siri • Add Foldling to an iOS Focus so it opens on your session, or on the bedroom for a Sleep Focus • Calm sounds you can mix, three at a time, with a paper window that shows what you hear. They play on when the phone locks, if you like • Keep the screen on while you focus, or hide the countdown and watch only the folds • A shelf of cranes and a simple week view, no streak to lose • On iPhone Duo, stand it like a small laptop: Kit and the time sit up top, the controls lie flat • Gentle reminders, only if you allow them: when a session ends, when Kit is hungry, and a weekly look back. Quiet hours included SLEEP WITH KIT • Rain, a stream, piano and white, pink or brown noise are free, and they play on when the screen locks • A 15- or 30-minute sleep timer that fades out, and a lamp that dims to true black • An optional wake alarm at the time you choose, off until you turn it on • Nothing pops up over the dark room, and Kit's notes stay silent in quiet hours • A small good-morning card the next day • Sleep sounds only: Foldling does not track or measure your sleep MADE FOR THE FOLD, PLAYABLE EVERYWHERE Built first for iPhone Duo, where the hinge is the valley. Every part also works on other iPhones with touch and tilt. CALM BY DESIGN • Cut-paper art, soft sounds and gentle haptics • Calm effects mode, and Reduce Motion is respected • No ads • Analytics stay off until you say yes • Optional Face ID lock FOLDLING PLUS One purchase, no subscription. Feeding, petting, play and every scene stay included for everyone. Plus adds: • Longer focus sessions: 45, 60 or 90 minutes, or your own length • Longer sleep timers: 45, 60 or 90 minutes, or all night • Extra decor for the big house, marked "Included in Plus" in the shop • A Night style for the widgets • More crane papers and desk decor • 17 more sounds, from the ocean and a fireplace to guitar and flute, and three lamp shades for the night • Sync your pet across your iPhones Plus can be restored at any time from Settings.

Verdict
The clearest difference is in-app purchases: Loop Sphere at none against Foldling's 1. Loop Sphere also leads on iOS requirement (17.0 vs 26.0). Foldling's advantage is ads (none vs shown). On price and device support there is nothing between them.
