Download the apps

Two ways to install our apps: automatically via Obtainium, or directly from GitHub.

🟢 Recommended method — Obtainium

Obtainium is an app that watches GitHub Releases and installs updates automatically. You install it once, give it the URLs of our apps, and you're done.

1. Install Obtainium

Download the latest version from the official repository:

Obtainium on GitHub

2. Add our apps in Obtainium

In Obtainium → "+ Add app" button → paste each URL below:

https://github.com/gitubpatrice/PDF-TECH
https://github.com/gitubpatrice/READ-FILES-TECH
https://github.com/gitubpatrice/pass_tech
https://github.com/gitubpatrice/ai_tech
https://github.com/gitubpatrice/notes_tech
https://github.com/gitubpatrice/health_tech
https://github.com/gitubpatrice/SMS-TECH
https://github.com/gitubpatrice/APP-MANAGER-TECH

3. That's it

Obtainium will notify you of every update and install it in one click. No data sent to any third-party server.

🟡 Direct method — GitHub Releases

For a one-off APK download.

App Link APK to pick
PDF Tech Releases app-arm64-v8a-release.apk (modern phones)
Read Files Tech Releases app-arm64-v8a-release.apk
Pass Tech Releases app-arm64-v8a-release.apk

Notes Tech Releases app-arm64-v8a-release.apk
Health Tech Releases app-release.apk
SMS Tech Releases app-arm64-v8a-release.apk
App Manager Tech Releases app-arm64-v8a-release.apk

Verify integrity (recommended)

Each Release publishes a SHA-256 hash in the notes. On Android, you can verify it with an app like "Hash Droid", or on a PC:

sha256sum app-arm64-v8a-release.apk

The output must match exactly the hash published in the release notes.

📦 Shared code across apps

The Files Tech apps use a common foundation published separately: files_tech_core (Apache 2.0). It groups the shared services: update checks, cloud sharing, legal pages, formatting and path-safety helpers. You don't need to install anything extra — this code is already bundled in every APK. The separate repo is only for auditors and contributors who want to build the apps from source.

⚠️ If you're on Samsung

Samsung One UI 6.1+ ships an "App security" feature (Auto Blocker) which can block installation and silently revoke the "All files" permission.

If an app refuses to install or can't see your files: Settings → Security and privacy → Auto Blocker → Disable.
