Editor's Overview

LaBLEr is a connectivity application developed by toolicious, packaged as a single Android APK of version 1.3 weighing in at 3.93 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 3.93 MB, so it installs quickly even on modest connections.
This build is signed by "toolicious" — 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

LaBLEr is a label printer app for Bluetooth Low Energy thermal label printers of the Marklife family (P15, P12, L13). Design your own labels right on your phone, save them as templates, and print them again anytime. It talks to the printer directly over Bluetooth LE, with no account, no cloud, and no vendor app.

Features:

* Multi-line text (size, bold/italic/underline, alignment, several bundled fonts plus your own TTF and OTF files), symbols and emoji, frames, imported images, and QR codes and barcodes (Code 128, EAN-13, UPC-A, Code 39, ITF) with typed QR content for links, Wi-Fi, email, phone and contacts.
* A direct-manipulation editor: pinch to zoom and pan, drag to move, resize and rotate, with snapping to the center, the edges and other elements. Graphics render for the 1-bit thermal head as a clean outline (region tracing or Canny edge detection, with a smooth pass and invert) or with a threshold, Floyd-Steinberg or Atkinson dithering.
* Templates: save, rename, duplicate, favorite and search; export a single label as a JSON file, or back up and restore your whole library.
* Placeholders for the date, the time, a running number, or a free-text value you are asked for at print time.
* An exact 1-bit preview, a choice of copies and die-cut or continuous media, and a print history you can reproduce.
* Reconnects to your saved printer automatically. Available in 17 languages, Material 3 design, light and dark following the system.

Privacy: LaBLEr is a fully local app. It does not declare the INTERNET permission, so the process cannot open a network connection at all. No account, no cloud, no analytics, no tracking. Your templates, print history and settings live in the app's private storage and never leave the device.

Only the P15 is verified on-device so far; the P12 and L13 use the same protocol and 12 mm (96-dot) print head.

Frequently Asked Questions

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

Is LaBLEr safe to install?
We link to the exact APK published by toolicious. 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 LaBLEr?
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.
