Calculate alcohol mass, content and volume in drinks.
About this app
VPT#018-VPC is an android app that swiftly calculates the mass of alcohol (in grams) contained in a given volume of a beverage (in milliliters) when alcohol content (Vol.-% or v/v) is known.
It uses the formula: mass (g) = volume (mL) * Vol-%/100 * specific weight of alcohol (0.793 g/mL)
Features:
* 🖩 Calculate mass, or volume, or content (v/v) of an alcoholic beverage by entering the 2 other data points. * 🎨 Intuitive Interface - Clear buttons and layout, simple to understand. * 🔄 Dynamic Field Adjustments - Modify any data field post-calculation, and the app will update the other relevant fields (right now function via pressing "Calculate" again after modifying fields). * 🚨 Plausibility Warnings - The screen will flash red if any of the values are totally out of place, such as above 100% alcohol content or volumes above 10 liters, informing the user that something probably went wrong. Calculation still finishes. * Localization - Right now: English, German
Usage: 1. Enter your data in any 2 of the 3 fields 2. Tap "Calculate" 3. View your results 4. To clear all 3 fields, tap the "clear" Button.
🚨DISCLAIMER🚨: This is NOT a medical application NOR a medical product. This is just a calculator. Correct results are not guaranteed. User is responsible for checking results and plausibility.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be v4lpt.vpt.i018.vpc is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.0.4 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Valentin's PowerTools #018 - Volume Percent Calcul first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Valentin's PowerTools #018 - Volume Percent Calcul, and a listing is removed when the evidence for it stops holding up.
