Foldling
Read full descriptionHide full description
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.

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.

Foldhide

Foldhide turns iPhone Duo into the thing you used to carry in your pocket. Closed, the cover is plain full-grain leather. Open it and you are looking inside a real bi-fold: six card slots with a deep thumb pocket, a cash compartment with a folded note, a pen in its loop, a receipt tucked in the last slot. Everything behaves like the real object. ⢠Pull a card out of its slot with a tap, turn it over to see the back. ⢠Cards are real size and the metal reacts to how you hold the phone. ⢠Tap the receipt to pull it out and read it. Tap the note to unfold it. ⢠Drag a card to the other side to rearrange your wallet. ⢠Tap the pen to add your own cards, edit them or change their order. Pull a card and tap Edit Card to change its name, metal and balance. ⢠The wallet never rotates: the cover is upright, the inside is wide open, exactly like leather. Foldhide is designed for iPhone Duo and uses both of its screens. It keeps everything on your device: there are no accounts, no tracking and no network access.

Verdict
The clearest difference is in-app purchases: Foldhide at none against Foldling's 1. Foldhide also leads on update cadence (daily vs fortnightly) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
