ToolixHub

An offline-first Android multitool application featuring a comprehensive collection of daily utility tools built for modern mobile devices.

ToolixHub

Made by Zykrave

ToolixHub brings together a comprehensive collection of daily utility tools in a clean, modern Material 3 interface. Built with Kotlin, Jetpack Compose, Material 3, and AndroidX, ToolixHub is designed as an offline-first utility knife for everyday tasks. All core tools execute completely on your device without transmitting your data. Network access is utilized exclusively when you explicitly initiate a software update check against GitHub Releases.

ToolixHub was created by Zykrave.

Official releases for ToolixHub are published on GitHub. You can find the main repository and download official APK releases directly from:

• 🔗 Repository: https://github.com/Zykrave/ToolixHub
• 📦 Official Releases: https://github.com/Zykrave/ToolixHub/releases

How Software Updates Work:

• ToolixHub includes an optional manual update checker located under Settings → About.
• The app contacts the GitHub API only when you explicitly press "Check for Updates".
• The update checker compares your installed version against the latest release published on GitHub.
• If a newer release is found, the app informs you that an update is available.
• The current implementation does not automatically download or silently install APK updates. Users can manually download updated APKs from the official GitHub Releases page.

You can build ToolixHub locally using Android Studio or the Gradle wrapper.

• IDE: Android Studio (Ladybug / Hedgehog or newer recommended)
• JDK: Java 11 or higher
• Compile SDK: 36
• Target SDK: 36
• Minimum SDK: 24 (Android 7.0+)

1. Clone the repository:

git clone https://github.com/Zykrave/ToolixHub.git
cd ToolixHub

2. Open the project in Android Studio and allow Gradle to sync.

3. To build a debug APK via command line:

   • On Linux / macOS:

     ./gradlew assembleDebug

   • On Windows:

     gradlew.bat assembleDebug

• Debug Builds: Debug builds work out-of-the-box using the pre-configured debug.keystore supplied in the project root directory.
• Release Builds: Release builds require setting the environment variables KEYSTORE_PATH, STORE_PASSWORD, and KEY_PASSWORD to point to your signing key.

ToolixHub is designed with user privacy at its core:

• Local Execution: Core tool functions (image processing, text calculations, sensor telemetry, hash generation) run entirely on your physical device.
• Zero Trackers & Analytics: The application contains no analytics SDKs, user tracking, or telemetric data collection.
• Zero Advertisements: There are no ads or commercial network scripts included.
• Explicit Network Use Only: Network access exists specifically for the user-initiated software update check in Settings → About. The app does not continuously contact a server for normal tool usage, and your personal data or generated content is never uploaded.
