## What is Proof Meister?

DISTILL SMARTER. MEASURE ABV. STAY IN CONTROL. 
Proof Meister makes it easy to measure, monitor, and manage your distilling process. Whether you're making gin, whisky, vodka, grappa, or liqueurs, measure alcohol content, track distillation cuts, and organize your production runs — all in one app. 

Pair the app with EasyDens, SmartRef, or pH2Go to record precise measurements with ease. Measure density, refractive index, and pH with your Tony measuring devices. Combine EasyDens and SmartRef to determine ABV in liqueurs. 

No measuring device? You can also enter readings manually. 

TRACK YOUR PROCESS FROM MASH TO BOTTLING 
Stay in control of your spirits production, from fermentation to the finished product. 

- Monitor pH during mashing and fermentation 
- Measure ABV and proof throughout distillation 
- Document foreshots, heads, hearts, and tails during distillation 
- Log measurements at each stage to support decisions on distillation cuts 
- Track measurements during blending and bottling

RESULTS WITH CONTEXT 
Go beyond the measurement and understand what your results mean at each stage of the distilling process. 

- Select your spirit type, such as gin, vodka, whisky, or grappa 
- See expected ABV ranges based on the spirit you're making 
- Get measurement guidance that matches your distilling process 
- Check alcohol content and proof to reach your target bottling strength 

MEASURE SMARTER, CALCULATE LESS

- Measure ABV and proof with EasyDens 
- Determine ABV in liqueurs with EasyDens and SmartRef 
- Automatic temperature compensation without manual correction tables 
- Switch between ABV (%v/v, %w/w), US Proof, and UK Proof 
- Measure in a range of units, including ABV at 15 °C and 20 °C, US Proof (60 °F), UK Proof (20 °C), density (g/cm³), and temperature (°C/°F) 

MANAGE RUNS & COMPARE RESULTS 
Keep your distilling history organized and use previous results to improve consistency from run to run. 

- Create custom batches and organize measurements with notes and timestamps 
- Save distillation runs, measurement notes, and project notes for recipes 
- Compare results across distilling runs 
- Find previous measurements and batches with full-text search

### 2/5 — Sort of works

*2026-09-03*

It’s glitchy, temperamental, and not water proof.  Which is funny considering it measures liquid.
It works about half the time.  Currently it neither device will connect to Bluetooth, which makes it essentially useless.

### 3/5 — Poor UX

*2026-07-31*

“Values out of range” blocks instrument selection button. 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 — Gutes Gerät und gute App

*2022-09-19*

Meine erste Messung lief problemlos, bin sehr happy, ideal für die schnelle Messung zwischendurch

### 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.
