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 6.64 MB, so it installs quickly even on modest connections.
This build is signed by "Rastislav Kish" — 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

This is a little project of mine aiming to research how vision LLMs could help out blind people on travel and in their every-day life by substituting eyesight for various visual tasks. VScan turns your smartphone's camera into a device for visual perception. You can define various optical cognitive functions, like looking for objects, signs, evaluating a scene or simply mediating visual impressions. You can afterwards use these functions on the camera view, just like a sighted person would use their eyes to achieve a specific goal in the physical world.

Each cognitive tool consists of two major parts:
• The camera to be used - front / back, as well as camera parameters - resolution, flashlight etc.
• The prompts used for LLM processing. LLM is the bridge between raw pixel data and your interpretation of it, and in the user/system prompt, you can specify what exactly are you interested in for the particular function and how should it be communicated, as well as the LLM model that should be used.

Camera input in combination with an LLM processing prompt forms a cognitive function, which can be used to serve various visual tasks.

VScan is open-source software. Visit the project's official repository to learn more about its background, motivation, specific usage examples and setup instructions.

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

Is VScan safe to install?
We link to the exact APK published by Rastislav Kish. 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 VScan?
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.
