Proof Meister is a mobile app developed by Anton Paar ConsumerTec GmbH for iPhone users. It is a utility tool in the category of Utilities & Tools. The app is designed to work in conjunction with the EasyDens digital density meter by Anton Paar.

With the EasyDens device, you can obtain highly precise results in just seconds and accurately determine the alcohol content of your spirits. The Proof Meister app acts as a perfect guide throughout your distillation process, providing support in data storage, management, visualization, and exportation.

The app reports results in various units, including density, alcohol by weight, alcohol by volume, alcohol by volume at 15°C, alcohol by volume at 20°C, °Proof UK, and °Proof US. Temperature readings can be displayed in Celsius or Fahrenheit, and all concentration values shown on your phone are already temperature-corrected, eliminating the need for further calculations and correction tables.

Please note that an EasyDens device from Anton Paar is required for density and concentration measurements.

The app offers auto-renewable subscription plans, billed monthly or annually. Please review the terms and conditions regarding subscription cancellation and renewal.
