Editor's Overview

Libellus Potionis is a sports & health application developed by Martin A. Godisch, packaged as a single Android APK of version 0.8 weighing in at 4.43 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 4.43 MB, so it installs quickly even on modest connections.
This build is signed by "Martin A. Godisch" — 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

Libellus Potionis is a privacy-first, open-source, free and ad-free alcohol consumption tracker designed to help users monitor, pace, and manage their drinking habits entirely offline. It requires no invasive device permissions—no camera, microphone, or location access—and operates completely without network connectivity.

KEY FEATURES

• Logging: Predefine your own beverages or pick from internationally common presets. Log drinks instantly or retroactively with timestamp corrections.
• Concurrent limits: Set three boundaries at once — a daily limit (grams of pure alcohol), a rolling 7-day weekly limit (grams), and a maximum number of drinking days per week. Each has its own progress bar.
• Blood alcohol concentration (BAC): Enter your body weight to get a live estimate from the Widmark formula.
• Counseling reports: Generate a two-page PDF report of your consumption for consultations and counseling appointments.
• Data portability: Export your dataset as a CSV file for external processing (e.g. in LibreOffice Calc), or create JSON backups to move data between devices.
• Adjustments: Set your own “day start” time, so that late-night drinks count toward the preceding evening, and an evaluation start date for a clean restart, e.g. on New Year’s Eve.

A User’s Guide is available inside the app.

PRIVACY & SECURITY

The app stores only what you enter. It holds no network permission, so it is incapable of network access and your data cannot leave the device by itself. Your data stays in the app’s private storage, protected at rest by Android’s device storage encryption and the app sandbox. An optional biometric fingerprint lock guards against unauthorized physical access. There is no tracking, no analytics and no cloud synchronization.

COMPATIBILITY

The app runs on Android 11 (API 30) and newer and is also available for iOS 17 and newer.

OPEN SOURCE

Libellus Potionis is free software released under the GNU General Public License v3 (or later). The source code is available at the project homepage.

Frequently Asked Questions

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

Is Libellus Potionis safe to install?
We link to the exact APK published by Martin A. Godisch. 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.

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.
