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.

Cannot select measurement unit until a measurement is started, often causing “unit not compatible” to float over part of the UX. Neither of these floating windows can be “dismissed” or closed, they just stay in the way. Temperature now only displayed on swipe up, instead of alongside core measurement display(why not just show all the reading data) Generally just poor UX design. A few very simple quality of life improvements would be very helpful. ### 3/5 — Taking feature away *2025-06-26* Please add Brix back to proof master. It was taken away with latest update. **Developer response:** Thank you for your feedback. Brix was added back again. ### 1/5 — Doesn’t work without subscription and buying another device *2024-09-02* Forces you to buy a subscription and the smart ref to work **Developer response:** The SmartRef works fully without any subscription. Please feel free to reach out to us at support@my-smartref.com so we can clarify any misunderstanding and assist you further. Thank you. ### 1/5 — Crippled app to force unnecessary subscription *2023-10-19* For a $350-400 tool, I expect this app to be free and self-contained. They could store all your batches in iCloud, but instead are trying to upsell you on their own cloud storage service. Then they split the functionality into three separate apps so they can sell you three subscriptions. I would think twice before buying another Anton Paar product. **Developer response:** Hi, we apologize for any issue you might be having! Could you send details of what you are experiencing to our customer support at support@easydens.com? We'll get you up and running. Thank you. ### 1/5 — Way to downgrade *2023-03-02, version 2.3.1* The new update no longer allows me to see proof into the decimal point range. Great change ### 5/5 — Great Product *2022-09-18* Amazing and easy to use **Developer response:** Hi, Thank you very much for your review! We appreciate your feedback! All the best! ### 5/5 — Amazing *2022-05-11* Such quick and accurate results! **Developer response:** Hi, Thank you very much for your review! We appreciate your feedback! All the best! ### 4/5 — Much improved *2022-03-17* On the previous incarnation of the app I had to do temperature conversion to 20 centigrade manually, so now this is built in it is a great time saver. The whole Easy Debs system is a massive time saver on manual measurements for abv of distilled spirits. It does the one thing I need it for very well. ## Frequently asked questions about Proof Meister ### What is Proof Meister?
