⚠️ Read this first: On iPhone there is exactly one source for the OKX app — the App Store — and the China mainland store does not list it. That is a measured result, not a rumour. If you do not have an account yet, start from the registration entry — the referral relationship is fixed the moment you register, and signing up inside the app afterwards usually cannot restore it.
Key points (TL;DR):
- OKX download and Ouyi download point to the same app, and on iOS there is one source only: the App Store. iOS does not allow sideloading; anything asking you to install a profile, trust an enterprise certificate or join a "fast TestFlight build" is not official.
- China mainland really is missing. On 14 November 2026 a lookup against Apple's API with country=cn returned zero results, while the same query for WeChat in cn returned two — so the store works and OKX is genuinely not listed.
- Four hard facts to remember: developer OKX Inc., bundle ID com.okex.OKExAppstoreFull, version 6.197.2, size 849,934,336 bytes (about 810.6 MiB).
- OKX Wallet is a different app. Developer OKX Technology Inc, bundle ID com.okx.wallet. It is a self-custody Web3 wallet, not the exchange.
- Skip the region switch and use the web app. Login, KYC, orders and withdrawals all work; you only lose push notifications.
Bottom line: the iPhone build of OKX can only be installed from the App Store, China mainland does not list it, so you either switch Media & Purchases to a supported region, use an Apple ID you already have in such a region, or skip the switch and use the web app. Each route has a cost. Below: how to run each one, what can go wrong, and how to confirm in seconds that the app you installed is genuine.
First, work out which app you actually need
This is the step people get wrong before they even start switching regions.
OKX publishes two completely different iOS apps:
| App | Store name | Developer | Bundle ID | What it is for |
|---|---|---|---|---|
| Exchange | OKX: Buy Bitcoin BTC & Crypto | OKX Inc. | com.okex.OKExAppstoreFull |
Buying, spot, futures, earn, C2C |
| Wallet | OKX Wallet: Buy Crypto & RWA | OKX Technology Inc | com.okx.wallet |
Self-custody wallet, DApps |
Terminology first: OKX's Chinese name is 欧易 (romanised Ouyi), and 欧意 is a common typo of those characters that reads the same. Both refer to the same exchange app. An "OKX download on iPhone" means the first row, not the wallet.
Why this matters: install the wallet by mistake and you get a shell with no exchange account, no KYC and no C2C entry point — then conclude that OKX "does not work". The icons look similar, both names contain OKX, and they sit next to each other in search results.
Measured on 14 November 2026: four hard facts from the App Store
These numbers are not copied from a tutorial. They come from Apple's own lookup API on that day.
| Item | Measured value |
|---|---|
| Developer (sellerName) | OKX Inc. |
| Bundle ID | com.okex.OKExAppstoreFull |
| Version | 6.197.2 |
| Version release date | 2026-11-13 05:39 UTC |
| Size | 849,934,336 bytes (810.6 MiB, about 850 MB decimal) |
| Minimum system | iOS 15.0 |
| Price / category | Free / Finance |
| App Store ID | 1327268470 |
These four are the whole verification. There is no fifth. On the App Store page, scroll to the Information section to see developer, version, size and compatibility. The bundle ID is not displayed, but if the developer and version match you are almost certainly on the right listing, because Apple binds the developer name to a verified legal entity.
For reference the wallet reads: version 6.197.0, 530.2 MiB, also iOS 15.0 minimum.
Version numbers change; do not use them as your only test. Tutorials from 2025 still quote 848 MB and 6.19x — correct then, wrong now. The stable anchors are the developer name and the bundle ID.
China mainland is missing — measured, not rumoured
Plenty of articles state that the mainland store has no OKX. Almost none show how to check. Here is the method; you can repeat it yourself.
Query Apple's public lookup endpoint with the region parameter set to cn:
lookup?id=1327268470&country=cn→ zero results- Control:
search?term=wechat&country=cn→ two results (WeChat, WhatsApp Business)
The control matters. If the cn store were simply unreachable, zero results would prove nothing. The same endpoint returns WeChat normally, so the store answers and OKX is genuinely absent.
The same endpoint returns one result for hk, sg, jp, tw and us. So what you need is an Apple ID in a supported region — not a "special download link".
This is also why most "one-tap install" pages are fake: Apple controls iOS distribution. No third party can push an unlisted app into an iPhone from a browser.
Three routes to install on iPhone
Ordered by how much effort each costs:
| Route | Best for | Cost |
|---|---|---|
| Switch Media & Purchases only | Daily driver, long-term use | Needs a regional address and payment method; original-region content is unavailable meanwhile |
| Use an existing foreign Apple ID | People who already have a US or HK account | Account credentials to manage, more than one account |
| Skip the switch, use the web app | Occasional chart checking | No push notifications |
Route 1: switch only Media & Purchases
The key point: you switch "Media & Purchases", not the whole iCloud account. Tutorials blur these two constantly, and that blur is what makes people think they must replace their Apple ID.
On iPhone: Settings → your name → Media & Purchases → View Account → Country/Region → Change Country or Region. The system asks you to complete an address in that region and, in some cases, to add a payment method valid there.
Three cautions:
- Clear any remaining balance first. An account with store credit or active subscriptions usually cannot change region.
- Your iCloud data is untouched. Photos, contacts and notes belong to the iCloud account, which does not change when the store region does.
- Updates follow the region. Once you switch back to China mainland, this app stops receiving updates until you switch out again.
Route 2: use an Apple ID you already have abroad
Sign in to the App Store with the existing US or HK account and search. Sign in to Media & Purchases, not to the whole device.
After installing, you do not need to stay in that region — the app is on the phone, and signing in to OKX uses your OKX account, not your Apple ID.
Route 3: skip the switch entirely
This route is badly underrated. The OKX web app handles login, identity verification, spot and futures orders, and withdrawals. What you lose is push notifications and the feel of a native app.
If you mostly want to look at the market and occasionally adjust, switching regions to install an app is poor value. Start with the web app for two weeks and switch only if you genuinely use it daily.
Four kinds of page that appear for this search
Searches for OKX download on iPhone return four categories. Only one is usable for installing.
| Page type | Tell | Install? |
|---|---|---|
| Official help page / App Store listing | Domain is okx.com, or it opens the App Store | ✅ Yes |
| Tutorial site | Explains steps, sends you to the App Store yourself | ✅ As reference; install in the App Store |
| "iPhone direct install" / enterprise signed | Asks you to install a profile, trust a certificate or use TestFlight | ❌ Not an official channel |
| "OKX mirror" / "high-speed download" | Domain contains okx but is not okx.com | ❌ Fake |
One hard rule: on iOS there is no such thing as "downloading an installer". Any .ipa file, configuration profile or enterprise certificate you are handed should not go near your main phone — that path bypasses Apple's review, and nobody can tell you what was added.
Before you sign up, fix the order
This is the step most readers skip, and the most expensive one to get wrong.
The order is: register with the referral relationship bound, then sign in to the app. Installing before or after registering does not matter; what matters is whether the relationship was bound at the moment of registration.
The official help centre is explicit: the referral relationship is set at registration and cannot be added or changed afterwards. An account created by tapping "Sign up" inside the app is typically clean — no fee discount, no new-user task eligibility, and no self-service channel to fix it later.
So the correct sequence:
- Register through the registration entry, binding the relationship.
- Sign in to the app with that same account.
- Check the account page for the referral or fee-discount marker.
If step 3 shows nothing, the binding did not take. Handling it before you trade costs the least.
The five problems iPhone users hit most
| Symptom | Usual cause | What to do |
|---|---|---|
| App not found | Store region is China mainland | Switch Media & Purchases or use a foreign ID |
| Install spinner then failure | Address or payment method incomplete after switching | Return to the account page and complete it |
| "Requires a newer version" | System below iOS 15.0 | Update iOS, or use the web app |
| Opens then crashes | Borderline OS version or stale data | Delete and reinstall; then check the OS version |
| Suddenly asks to sign in again | Expired session or region switch | Sign in to the same account — do not create a new one |
On crashes specifically: if a reinstall still crashes, do not go looking for a "fixed installer" — that is almost always phishing. Confirm your iOS version meets 15.0 and that the build did not come from an unofficial channel.
Three checks worth two minutes before you register
- Confirm you are on okx.com, not a lookalike domain. Mainland-facing variants such as okx.com.cn or okx-cn.com are not official.
- Confirm the registration entry carries the referral relationship. If you register manually, fill it in yourself; if the field is prefilled with someone else's code and cannot be changed, close it and start again.
- Confirm you installed the exchange app, not the wallet. OKX Inc. is the exchange; OKX Technology Inc is the wallet.
Doing all three after installing and before trading costs the least.
FAQ
Can I find OKX in the China mainland App Store? No. On 14 November 2026 a lookup against Apple's API with country=cn returned zero results, while the same query for WeChat in cn returned two — so the store works and OKX is genuinely not listed.
Is the iOS app different from the Android app? Features are essentially the same; distribution and updates differ. iOS updates arrive via the App Store; the Android APK does not auto-update. Both use the same account system.
Is a developer name of OKX Inc. enough to prove it is genuine? Inside the App Store, essentially yes — Apple verifies and binds the developer name. That protection stops at the App Store boundary; a website download button has none of it.
Will switching region wipe my data or apps? No. Switching Media & Purchases does not clear iCloud data or uninstall apps. Original-region subscriptions and purchases are unavailable while switched, and return afterwards.
Can I use OKX without switching region? Yes. The web app covers login, KYC, orders and withdrawals. You lose push notifications only.
I already installed the app. Can I add a referral code now? Per the official help centre, the relationship cannot be added or changed after registration. What matters is whether it was bound at sign-up.
Are the tutorial sites ranking for OKX download safe? As reference, maybe. But the install can only happen inside the App Store. Any iOS instruction involving profiles, enterprise certificates or TestFlight links is not an official channel.
Verification notes
Version, size, developer, bundle ID, minimum system version and release date were taken on 14 November 2026 directly from Apple's iTunes Lookup and Search APIs rather than from third-party pages: exchange app id=1327268470, wallet app id=6743309484, size as the raw fileSizeBytes figure.
Regional availability comes from the same endpoint queried with cn, hk, sg, jp, tw and us; cn returned zero results and every other region returned one. To rule out the cn store being unavailable altogether, the same endpoint was queried with term=wechat&country=cn, which returned two results.
Version numbers and package size change with each release; use the values at the moment you check. Judge authenticity by the developer name and bundle ID, which are stable. Apple ID region switching changes with iOS versions — follow the on-screen prompts when you do it.
This is not investment advice. Crypto prices are volatile. Only commit funds you can afford to lose, and never share your seed phrase, verification codes or password — no exchange support agent will ask for them.
