Coming soon

The iPhone version is being prepared for the App Store and will support iOS 15 or later (iPhone 6s and newer). We’ll update this page when it’s available.

Installation tips

  1. Open this page in your phone’s own browser to download. Pages opened inside other apps, such as chat apps, often can’t download APK files; use the app’s menu to choose “Open in browser”.
  2. When the download finishes, tap the file to install it. If your phone says installing unknown apps is blocked, follow the prompt to Settings, allow your browser to install apps, then go back and continue.
  3. Some phone brands run a security scan or have a “pure mode” that blocks apps from outside their app store. Once you’ve confirmed the APK came from this site, choose to continue installing.
  4. You can check the SHA-256 checksum before installing to make sure the file hasn’t been tampered with: on a computer, run shasum -a 256 <file name> (macOS) or certutil -hashfile <file name> SHA256 (Windows). The result should match the checksum shown on this page.
  5. This is the China mainland build, so your account and data are stored in mainland China. A version for other regions will be released through app stores later.

After installing

On the spare phone, choose “Watch the tank”, then scan its QR code with your everyday phone to pair.
