Yes — every case is precision-tooled per device generation, not a one-size shell. Pick your exact model on the product page (each generation is a separate variant) and the cutouts, hinge clearance and camera openings will line up exactly.
Yes. The iPhone Duo has MagSafe built in, and our magnetic cases carry an N52 ring positioned over it — chargers, wallets and car mounts snap on through the case with no charging slowdown. Hinge cover cases seal the fold mechanism; two-piece slim cases leave the hinge free so the Duo still closes flat.
Free tracked shipping on every order. Typical delivery to your region is 5–7 business days, with a tracking link the moment your order ships. You can follow every step on our live order-tracking page.
Every order has 30-day returns and a 12-month manufacturer warranty. If the case does not fit your phone or does not feel right, contact us and we will sort a replacement or refund — no forms, no fuss.
Holds onto my MagSafe charger very firmly. I was surprised since most cases have complaints of weak magnet strength. The overall quality is great considering the price.
Of the best cases I have bought. The two-piece design seats flush and the magnetic hold has strong force and sticks well.
This company is reputable and the case is what I wanted. Not max protection, but with today's phones I am not sure max protection is needed.
No. The iPhone Duo has its own dimensions, hinge profile and camera island — a Z Fold 8 or Fold 8 Ultra case will not seat on it. Every product in this collection has a dedicated iPhone Duo option; select it on the product page for the Duo cut.
Five series are cut for the iPhone Duo: the Apex M3 slim magnetic case, the Spineguard P1 and Kinetic P1 hinge covers, and the Axon M1 and Axon M2 ring-stand cases. All five are in stock and ship now; the launch deal takes 30% off every iPhone Duo case until 30 October, automatically at checkout.
Yes — the iPhone Duo has MagSafe built in, and our magnetic cases carry an N52-grade ring positioned over it, so chargers, wallets and car mounts snap on through the case with no charging slowdown.
No. Two-piece cases like the Apex M3 and Axon M1 leave the hinge completely free, so folding feels exactly as it does without a case. Hinge cover cases use a floating spine that moves with the hinge and closes flush.
The hinge is the most expensive part of any foldable to repair, and it is the part pocket grit works into first. A hinge cover case seals it in every position. If you prefer the slimmest possible profile, a two-piece magnetic case still protects the corners, camera and cover screen.
Free standard shipping worldwide. Free tracked shipping arrives in 5–7 business days, Express in 2–3 business days. Choose your option at checkout; orders ship within 48 hours (24 with Express).
30-day no-questions-asked returns. If the case doesn't fit your iPhone Duo or you're not satisfied for any reason, we'll refund or exchange — whichever you prefer.

iPhone Duo is the first foldable from Apple — and it gets its own FoldifyCase tooling from day one, not a stretched Galaxy shell. Five series are cut for the Duo at launch: the Apex M3 slim magnetic case, Spineguard P1 and Kinetic P1 hinge covers, the Axon M1 ring-stand case and the Sentinel H1 heavy-duty case.
The Duo has MagSafe built in, so our magnetic cases carry an N52 ring positioned directly over the Apple ring — chargers, wallets and mounts snap on through the case. Hinge covers use a floating spine that seals the fold in every position and still closes flush, and every case is measured on the Duo hinge line, camera island and cover screen rather than adapted from a Z Fold mould.
Surprisingly strong magnetism on the back. Holds onto my MagSafe charger very firmly.
We started FoldifyCase because foldable phone owners deserved cases as engineered as their phones. Off-the-shelf manufacturers retool slowly — they ship one universal flip case and call it done. We tool separately for every device generation, run drop tests against MIL-STD 810H protocols, and ship straight from our warehouse with free worldwide delivery.
Every case in this collection has a dedicated iPhone Duo option — hinge line, camera island and MagSafe ring all measured on the Duo, not carried over from a Galaxy Z Fold. Select iPhone Duo on the product page.
Tooled per-model to under 0.1mm tolerance. Every cutout, hinge line and camera ring lines up exactly.
Independently drop-tested to military standard 810H. Reinforced corners absorb impact away from the hinge.
N52-grade magnetic rings positioned for the wireless charging coil. Snaps cleanly to chargers, wallets and car mounts.
Every order, no minimum. Tracked delivery in 5–7 business days.
Manufacturing defects, hinge failure, magnetic ring detachment — covered. Email and we replace it.
No — the iPhone Duo has its own dimensions, hinge profile and camera island. Every product here offers a dedicated iPhone Duo option; a Z Fold 8 or Fold 8 Ultra case will not seat on the Duo.
Yes — hinge protection is our top priority. Most models feature reinforced hinge bridges, 360° wraparound coverage, or magnetic front panels that close flush against the cover display. Read each product page for the specific hinge protection method.
Many of our models include built-in N52-grade neodymium rings positioned over the wireless charging coil. Look for the "MagSafe-compatible" tag on individual product pages — these work with MagSafe chargers, wallets, car mounts and grip rings.
Every case ships with 30-day no-questions-asked returns plus a 12-month manufacturing warranty. If anything fails under normal use — hinge bridge cracks, magnetic ring weakens, materials split — we will replace it free. See our full return policy for details.
We ship worldwide for free. Free tracked shipping arrives in 5–7 business days, Express in 2–3 business days. Orders ship within 48 hours (24 with Express) and the tracking link comes by email. Full details on our shipping page.
