This build's target SDK is high enough to install on Android 13, 14, and 15.

Install on your tablet

  1. 1

    Download the APK

    Tap the download button, or scan the QR code with the tablet to open this page there and download directly.

  2. 2

    Open the file and allow this source

    Open the downloaded APK. When HyperOS asks, allow installs from this app (browser or Files). On HyperOS this permission is per-app, not global.

  3. 3

    Dismiss the unknown-app / Play Protect prompt

    Google's package installer may warn about an app from an unknown source or offer to scan it. Choose to install anyway (or 'Install without scanning').

  4. 4

    If install is blocked by MIUI optimization

    If HyperOS blocks it, open Settings > Privacy protection > Special permissions > Install unknown apps, pick your browser/Files app, and enable it. Then retry the APK. You can also turn off 'Scan apps before installing' under Security if it keeps interrupting.

Once installed, open the app and enter your license key to activate. Need a key? Request a license.
