⚠️ Read this first: This guide covers downloading and installing OKX. Installing the app is not the same as opening an account: the referral relationship is fixed at registration, and a bare in-app sign-up usually cannot be rebound later. If you have not registered yet, enter through the OKX registration link and confirm the invite-code field says ACE533225. Whichever exchange app you install, never take the installer from a third-party "download site."
Key takeaways (TL;DR):
- The hardest part of downloading OKX is not the download itself — it's the entry point. There is exactly one official download page:
www.okx.com/download(Chinese page at/zh-hans/download). Android, iOS, Windows and macOS installers all come from there.- Counter-intuitive #1: when the official site won't open, the worst move is searching "OKX download". What ranks on top is mostly mirror sites, phishing clones and keyword-spam portals — at best they bind your referral to someone else, at worst you install a repackaged fake and lose your account.
- Counter-intuitive #2: "it installs" ≠ "it's official". The only test is the source: did the installer come straight from okx.com? A working app with a convincing UI proves nothing.
- Counter-intuitive #3: downloading creates no referral relationship at all. The referral is fixed at the moment of registration by the invite code; rebinding afterwards is rarely possible.
- Not finding OKX in the mainland China App Store is not your fault — it's regional listing. You need a non-mainland Apple ID and should switch only "Media & Purchases", never iCloud.
- The number-one cause of failed Android updates is a signature conflict, not the network: uninstall the old version, install the new one, log in again.
Behind the search query "OKX download", most people's actual situation is: the official site won't open, or it opened and they can't tell which button is real. What goes wrong is rarely "which button to click" — it's two judgments: is this entry official, and where did the installer come from.
This guide covers, as of November 2026: the official channels for all four platforms, Android APK verification, iOS region switching, and seven download/install failure patterns — starting with the one rule that matters most: when the official site won't open, what you're missing is a route, not "another download site."
Official channels overview: four platforms, one entry
See the whole picture first, then pick your device's path. The OKX download page (www.okx.com/download) is the single entry for every platform; the Chinese page lives at /zh-hans/download, with separate regional entries (Singapore, UAE and others).
| Device | Official channel | Notes |
|---|---|---|
| Android (with Google Play) | Google Play, or the APK on the official download page | Prefer the store; APK only as a fallback |
| Android (no Google Play) | APK direct from the official download page | The only APK source you can trust |
| iPhone / iPad | App Store (non-mainland region) | Not listed in the mainland store; needs a non-mainland Apple ID |
| Windows / macOS | Desktop client from the official download page | Same entry as mobile |
| Nothing installed at all | Web version | Register and trade in a browser |
As of November 2026, the OKX download page offers iOS, Android, Windows and macOS only — there is no native HarmonyOS build. HarmonyOS 5.x no longer runs Android APKs; on such devices the web version is the only official route.
Step 0: if the official site won't open, don't search "OKX download"
This is the most important section of this guide. The OKX site is restricted on some networks: pages won't load, everything crawls, or the installer keeps cutting off halfway. The typical next move is searching "OKX download" — and that move fails far more often than the download itself.
The top results for "OKX download" are almost never official. Three patterns dominate:
- Mirror/relay sites: pages that look exactly like the official site but on a different domain. Some merely relay traffic; others are pixel-perfect phishing clones built to harvest your credentials;
- Keyword-spam portals ("fast-ranking sites"): pages stacked with "official download", "latest version", "one-click install" and almost no real content. Their installers may be genuine or repackaged — there is no way for you to tell;
- The downloader trick: clicking "download" first hands you a few-MB "downloader" that then "fetches" the real installer. You never learn what it actually fetched.
The risk comes in layers: mildest, your referral gets bound to the site owner (you registered through their link, so the rebate is theirs); worse, you install a repack (logins intercepted); worst, a phishing site drains the account directly. Every layer costs more than waiting a few extra minutes.
Do this, in order:
- Check the domain: the official domain is
okx.com(andwww.okx.com). Any lookalike — an extra hyphen, a different suffix, added digits — is not official; - Use the download page's regional entries: the official site serves region-specific download pages (
/zh-hans/download, Singapore, UAE and others). If one won't open, try another; - Retry on a different network: an unreachable site is usually a network problem, not a vanished website;
- On Android with Google Play, use the store: the store route doesn't compete with the website for connectivity;
- If none of that works, fix the access problem before downloading — never "just install" an installer from a third-party site.
In one line: when the official site won't open, what you're missing is a route, not "another download site." Download nothing that came from search results.
Android: APK download and installation
Take the APK from the official download page only — that is the one source you can trust.
- Open the download page in a browser (
www.okx.com/downloador/zh-hans/download) and choose the Android APK; - Tap the downloaded file to install. Android will ask you to allow "install unknown apps" — grant it for that browser or file manager only, not globally;
- Wait for the install to finish, then open the app.
Three checks before you log in:
- Source: did the installer come straight off the okx.com page? Anything passed through cloud drives, group chats or third-party "download sites" is untrusted by default;
- File: a complete APK (tens of MB at least). If "download" first produces a few-MB "downloader" or "accelerator", delete it;
- Behavior: the app should open to a normal sign-up/sign-in flow. Anything that asks you to "restore with a seed phrase" first is not an exchange app — exchanges never need your on-chain seed phrase; that request marks a wallet phish.
Update failures: if an Android update fails with "app not installed", "package conflict" or "signature mismatch", the most likely cause is a signature conflict (typically a previous install from a non-store channel). Fix: uninstall the old version, install the new one, sign in again. Your account and assets live server-side — uninstalling the app does not touch them. Don't keep force-installing out of fear that uninstalling "loses your coins" — that's a lost login session, not lost funds.
⚠️ On devices with Google Play, prefer the store: automatic updates and a controlled source eliminate the signature-conflict class entirely.
iOS: not in the mainland store — that's by design
The OKX app is not listed in the mainland China App Store, so mainland-region searches come up empty or return unrelated apps. That's regional listing, not operator error.
- Get a non-mainland Apple ID (registered with a region where OKX is listed);
- Open the App Store, tap your avatar, and switch only "Media & Purchases" to the non-mainland Apple ID. Do not sign out of iCloud — that affects photo, contact and device sync;
- Search OKX and install;
- Afterwards you can switch "Media & Purchases" back to your original region and keep using the app; switch back to the download region when you need an update.
Common snag: a non-mainland Apple ID may need a matching payment method or the "None" option. The registration flow for Apple IDs is beyond this guide; the one principle that matters: installing the app only ever touches "Media & Purchases", never iCloud.
Desktop client and web version
- Windows / macOS client: same entry as mobile — the official download page. The client gives you a dedicated window and price alerts; apply the same source check as on Android: installers from the okx.com download page only;
- Web version: open the official site in a browser — sign-up, KYC, trading and withdrawals all work there. On devices that can't run the app (such as HarmonyOS 5.x), the web version is the only official route; if you simply dislike installing things, it's also the laziest.
Download/install troubleshooting: match your symptom, in order
| Symptom | Most likely cause | Fix |
|---|---|---|
| Official site won't open | Network-level restriction | Verify the domain is okx.com; switch networks; try regional entries; never fall back to third-party sites |
| Installer download dies halfway | Network drop / low storage | Redownload; free up space |
| "Parse error" during install | Incomplete file or not an APK | Redownload from the official page; sanity-check the file size |
| Update fails with "signature mismatch" | Signature conflict | Uninstall the old version, install the new one, sign in again |
| Installed but crashes on launch | OS too old / incomplete file | Check OS requirements; redownload from the official page |
| Asks to "restore with a seed phrase" on launch | Phishing fake | Delete immediately; reinstall from official channels only |
| Antivirus flags the installer | False positives happen even for genuine builds | Allow it only if the source is the official page; delete any flagged file of unknown origin |
The rule of thumb: check the source first, the file second, the device last. If the source is wrong, no amount of device-side troubleshooting will save you.
Installed? The registration step decides who gets the referral
Downloading the app binds no referral at all. The relationship is fixed at the moment of registration by the invite code you type or the link you register through; rebinding afterwards is heavily restricted and often impossible.
- Enter through the registration link: the referral is applied automatically — confirm the invite-code field says ACE533225 before submitting;
- Registering inside the app: the invite-code field is optional; type ACE533225 manually. If it is prefilled with another code and locked, close the page and re-enter through a clean link;
- Installing first, registering later: a bare in-app sign-up usually carries no referral, so newcomer offers and the fee discount are lost.
💰 OKX registration: invite code ACE533225
Downloading and registering are free; what shapes your long-term cost is the trading fee. Bind invite code ACE533225 at registration to get the fee discount under OKX's current rules. This article contains a referral link; registering through it may earn us a reward without costing you a cent extra.
- Invite code: ACE533225 — the field must not be empty;
- How to enter it: the registration link fills it in automatically; in-app registration takes it manually;
- Important: the referral cannot usually be added after registration — confirm the code first, then submit.

FAQ
Which entry is the official OKX download?
One only: www.okx.com/download (Chinese page at /zh-hans/download). The Android APK, iOS, Windows and macOS installers all come from there. If it won't open, try the regional entries, another network, or Google Play — not the third-party download sites in search results.
Why won't the OKX website open?
Access to okx.com is restricted on some networks — a network problem, not a dead website. After confirming the domain spelling, switch networks or try the download page's regional entries. Don't grab installers from third-party sites just because the site won't open.
The App Store has no OKX — what now?
The mainland China App Store doesn't list OKX, so empty results are normal there. Sign into the App Store with a non-mainland Apple ID: switch only "Media & Purchases", never iCloud. After installing you can switch back; return to the download region for updates.
Where do I get the OKX APK, and how large is it?
From the OKX download page: tap Android, open the download FAQ and copy the APK link, or use the QR code on okx.com, or email download@okx.com as a fallback. OKX does not publish the Android package size or checksums, so any fixed "338MB" or "SHA-256" figure online is unverifiable. On iOS, the app measured 6.197.2, 849,934,336 bytes (~850 MB), developer OKX Inc. on 14 Nov 2026.
How do I verify the APK is official?
Check the source: did it come directly from the okx.com download page? "It opens and looks real" is not a test. A few-MB "downloader" first, or a seed-phrase prompt on first launch, means a fake — delete it.
OKX update fails with a signature conflict?
Uninstall the old version, install the new one, sign in again. Signature conflicts usually follow an earlier non-store install; uninstalling only drops the login session, never the server-side assets. On Google Play devices, switch to the store build for automatic updates.
Are OKX and OKX Wallet the same app?
No. The exchange app is published by OKX Inc. with iOS bundle ID com.okex.OKExAppstoreFull; OKX Wallet is a self-custody wallet by OKX Technology Inc, bundle ID com.okx.wallet. If you only want to trade, install the exchange app; anything that asks for a seed phrase is a wallet, not the exchange.
Where is the OKX desktop client?
The download page offers Windows and macOS desktop clients via the download icon → more clients → OKX desktop. OKX does not publish system requirements or installer size, so trust what the page shows; the web version can replace it if you only need multiple tabs.
Does downloading OKX cost anything?
Official downloads, installs and registration are free on every platform. Anyone charging for "download", "acceleration" or "guaranteed KYC" is running a scam.
Can I add an invite code after registering?
Rarely, or under heavy restrictions — the referral is fixed at registration. Enter through the registration link and confirm the invite-code field says ACE533225 before submitting.
Verification notes
The official entry and channel composition (iOS, Android, Windows, macOS; no native HarmonyOS build) were rechecked on 14 November 2026 against the OKX download page and the App Store lookup API (Hong Kong store: version 6.197.2, 849,934,336 bytes, developer OKX Inc.). Troubleshooting steps are generic Android/iOS procedures; exact error wording varies by OS version. OKX page names, regional entries and store availability may change — the official pages at the time are authoritative. This article links no third-party installers and recommends no downloads from unofficial channels.
Final reminder: downloads and registration are free; your long-term cost comes only from trading fees. Verifying the installer's source and binding the invite code at registration matter far more than chasing the "latest version".
