How to Download the OKX App (Android & iOS)
Accessing OKX starts with downloading the official app. The process differs slightly between Android and iOS devices due to platform restrictions.
For Android Users
Downloading OKX on Android is straightforward. Simply visit the official OKX website using your mobile browser and tap the “Download” button to install the APK file directly.
Once downloaded:
- Enable installation from unknown sources in your device settings.
- Run the installer and follow the prompts.
- Open the app and proceed to registration.
Always ensure you’re downloading from the legitimate OKX domain to avoid phishing scams.
For iPhone Users
Apple users in mainland China may face limitations when trying to download the OKX app from the local App Store. However, this can be easily resolved by switching to a non-mainland Apple ID.
Step 1: Create a Non-Mainland Apple ID
- Visit appleid.apple.com and select United States (or another supported region).
- Use a valid email address not previously linked to an Apple account.
- Provide a working phone number to receive verification codes.
- Complete registration by verifying your email and phone.
Step 2: Switch Apple ID & Download OKX
- Sign out of your current Apple ID in the App Store.
- Log in with your newly created overseas account.
- Search for “OKX” and download the official app.
After installation, you can switch back to your primary Apple ID for other downloads — the OKX app will remain functional.
With over 50 million users worldwide and recognized by TradingView as a "Most Reliable Technology" platform, OKX ensures high performance, fast execution, and robust infrastructure.

Creating an OKX account is quick and intuitive, whether you're using the mobile app or web version.
Mobile App Registration Steps

Complete KYC Verification for Full Access
Before buying or withdrawing crypto, you must complete three key steps:
1. Identity Verification (KYC)
- Navigate to Profile > Settings > Identity Verification.
- Upload clear photos of your government-issued ID (passport or national ID card).
- Complete facial recognition via the app.
- Wait for approval — typically within minutes.
KYC compliance helps prevent fraud and meets global regulatory standards.
2. Bind Phone Number
- Go to Security Settings > Phone Verification.
- Confirm your number via SMS code.
- Note: If registered via phone, this step may already be complete.
You can also bind an additional email for extra security layers.
3. Add Payment Methods
To buy crypto with fiat:
- Tap Buy Crypto > Quick Buy > More > Payment Methods.
- Add your preferred method: bank card, Alipay, or WeChat Pay.
- Verify ownership if prompted.
These methods allow seamless purchases of USDT, BTC, ETH, and other assets.

Buying Bitcoin has never been easier. Follow these simple steps:
Step 1: Access Buy Crypto Section
- Open the OKX app.
