Editor's Overview

Relatrix is a reading application developed by Saad Ibra, packaged as a single Android APK of version 2.0 weighing in at 28.55 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 28.55 MB, so it installs quickly even on modest connections.
This build is signed by "Saad Ibra" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Most knowledge-management tools are glorified bookmarks. You gather articles, highlight text, save links, and then forget everything. Relatrix changes that. Built on a single, uncompromising philosophy: Information only becomes knowledge when you engage with it through active reflection. Every resource you save is a starting point, not a destination. Relatrix provides a multi-modal toolkit to break down, question, and connect information across diverse formats.

Feature Overview:
- Topic Library: Organise your intellectual world into curated folders of resources. Visually organize topics with a fully customizable color picker. You can add web links, PDFs, markdown notes, and absolutely any kind of file as a resource.
- Multi-Modal Resource Timeline: A single chronological feed that unifies your reflections, annotations, and visual captures.
- Tag Management Hub: Manage, explore, and filter your resources across all topics using custom tags.
- Reflection-First Entry: When you save a PDF, web page, markdown note, or any other kind of file, Relatrix encourages you to capture an Opinion immediately.
- Knowledge Links & Tags: Cross-reference other resources, topics, or insights using [[double-bracket]] wiki-style links and organize entries with custom tags using a unified dropdown.
- PDF Reader & Annotation: Flip pages, highlight passages, create bookmarks, and perform web lookups.
- Note Editor: A minimalist markdown canvas designed for clarity.
- Relatrix 3D Knowledge Discovery: A live, physics-simulated 3D graph that renders the connective tissue of your knowledge base.

Frequently Asked Questions

Is Relatrix free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Relatrix require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Relatrix safe to install?
We link to the exact APK published by Saad Ibra. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Relatrix?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
