Proof Meister: Measure ABV6.7.3 - App Store

Proof Meister is your guide through every step of distilling - for spirits and liqueurs. Measure alcohol content and proof in seconds, master your cuts, and bottle at exactly the strength you want.

Connect your EasyDens density meter over Bluetooth and read ABV and proof in seconds - or add readings by hand. No device yet? You can still log, organize, and export measurements, then connect one whenever you're ready.

RESULTS WITH CONTEXT
Choose your style - gin, vodka, whisky, grappa - and Proof Meister tells you what your reading means:
- See whether your strength lands in the expected range for what you're making
- Read ABV in %v/v and %w/w, plus Proof US and Proof UK
- Confirm ABV at bottling down to the decimal
MASTER YOUR CUTS
- Track foreshots, heads, hearts, and tails as you run the still
- Spot the cleanest point to switch fractions for a cleaner, smoother spirit
- Log every reading against the moment it was taken
SKIP THE MATH
- Automatic temperature compensation - values are already corrected, no proof or correction tables
- Every scale from a single density reading - switch between ABV and proof instantly
MEASUREMENT UNITS
- Alcohol by volume (%v/v, plus at 15 °C and 20 °C), Alcohol by weight (%w/w), Proof US (60 °F), Proof UK (20 °C), Density (g/cm³), and Temperature in °C or °F.

A HISTORY YOU OWN
- Organize runs into custom batches with notes and timestamps
- Keep per-reading notes and project notes for your recipes
- Find anything instantly with full-text search
- Export to PDF for clean reports or CSV for spreadsheets
- Long-press any result to copy or share it
ONE ACCOUNT, EVERY DEVICE
A free Meister Cloud account syncs your batches across iPhone, iPad, Apple Watch, Apple Silicon Mac, Apple Vision Pro, and the web - one account for the whole Meister app family. Without an account, your data stays local on your device.
For density and concentration you need an EasyDens by Anton Paar.
