Editor's Overview

Logical Defense is a reading application developed by LukeStoneHm, packaged as a single Android APK of version 1.5 weighing in at 1.7 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 1.7 MB, so it installs quickly even on modest connections.
This build is signed by "LukeStoneHm" — 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

Prepare to battle against the sophists of the world with this beautiful app.

Steel yourselves, and begin to defend your mind from the language used against you by the sophists of the world.

They are many, we are few, but with the Logical Defense app, we now have an extra tool in our box of rationality.
Use this app to quickly look-up the logical fallacies we face when debating against the irrational.
Call out those who are logically flawed and help to build a more rational society.

Honesty is the first virtue, so let's be painfully honest towards those who attempt to use language as a form of mental abuse. Never accept a logical fallacy, attack the attacker, and spread logic and reason to those you love.

Ok, enough rambling. This is an app that displays a list of the logical fallacies that haunt every rationalists' mind.

Some features:

- Left drawer that houses categories.
- Share function -> Long press a fallacy to share it.
- Nice about screen.
- Language selection function.

This is a fully open-source project (GNU v2), and the source is hosted on GitHub so feel free to fork me :)

Feel free to leave your comments/suggestions. Thank you for downloading!

Frequently Asked Questions

Is Logical Defense 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 Logical Defense require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Logical Defense safe to install?
We link to the exact APK published by LukeStoneHm. 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 Logical Defense?
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.
