Editor's Overview

LocalMathy is a ai chat application developed by micr0, packaged as a single Android APK of version 1.0 weighing in at 36.76 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 36.76 MB, so it installs quickly even on modest connections.
This build is signed by "micr0" — 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

LocalMathy solves math problems entirely on your device. Nothing you type or photograph ever leaves your phone. With no account, no cloud, and no networking once the model is set up.

It runs VibeThinker-3B, a compact reasoning model, through Google's LiteRT on-device runtime. Ask a question and the app streams the model's step-by-step reasoning into a collapsible pane, then renders a clean final answer with full Markdown and LaTeX math.

Features

* Fully offline and private, all inference runs locally on the GPU (with a CPU fallback)
* Step-by-step reasoning you can expand or hide
* Answers rendered with proper Markdown and LaTeX math typesetting
* Tap a boxed answer to copy it
* Solve from a photo, snap or pick a picture of a problem, crop it, and an optional on-device vision model reads it into an editable question
* Optional local history of your questions and answers
* Light and dark themes

Getting the model

On first launch you download the reasoning model (about 1.9 GB) from Hugging Face, or import a .litertlm file you already have. It is stored on-device and only needs to be set up once. Photo solving uses a separate optional vision model you can add later.

Frequently Asked Questions

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

Is LocalMathy safe to install?
We link to the exact APK published by micr0. 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 LocalMathy?
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.
