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.

Volet
Read full descriptionHide full description
Volet is a studio for dressing iPhone Duo. A volet is one hinged leaf of a diptych, and iPhone Duo has exactly that shape. In Volet, every design is a piece, and a piece dresses all three faces of the phone: - The cover: what shows when the phone is closed or standing, cut to the cover's own silhouette, with a polished setting around the camera if you like. - The spread: two leaves across the open inner display, and the crease between them. - The hinge: what moves as you fold. Blocks part from the crease, rise into view, settle away, turn or drift, and a gold seam can pour out from the middle of the crease. Wear one of eight examples as it is, or make it yours. Build from blocks: the time (a dial, digits or words), the date, your words, your photos, a countdown, today's moon, shapes and your battery. Set them on colours, grained gradients or your own photographs, in fonts that ship with iOS. Tap to select, drag to move, slide Fold to watch the hinge motions before you wear them. Every piece you make is signed with your chop, a small cinnabar seal with your initials. Send a piece to a friend as a small .volet file; it opens straight into Volet and keeps a credit to the piece it came from. Stand the closed phone on its edges and the cover stays lit, like a clock on a desk or nightstand. Volet works while it is open. It does not change your wallpaper or Home Screen; iPhone Duo keeps those to itself. On other iPhones you can design, preview and share pieces, and wear the open spread. Free: every example, every block and every hinge motion, colours, gradients and photos, up to three pieces of your own, and sharing. Volet Pro adds as many pieces as you like, eight drawn materials (titanium, guillochΓ©, lacquer, enamel, aventurine, walnut, ceramic, suede) and gold and stitched creases: $0.99 a month, $4.99 a year with a 7-day free trial, or $9.99 once. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period, and can be managed in Settings > Apple Account > Subscriptions. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://volet-studio.vercel.app/privacy.html No account, no ads, no tracking. Nothing leaves your phone unless you share it.

Verdict
The clearest difference is in-app purchases: Volet at none against Foldling's 1. On price, ads, device support and iOS requirement there is nothing between them.
