Perfect Handheld App!

As a professional distiller, I have to constantly stop and calculate the proof of the product multiple times during the day. This app is great; it’s quick and easy to calculate proof on the fly while working and not have to interrupt your work constantly to figure it out longhand or leave the production area to do it on a computer. Love it.

FAQ

What is True Proof used for?

True Proof calculates the true proof of water-alcohol mixtures using hydrometer readings and temperature. It also performs gauging calculations and dilutions, considering the temperature-dependent mixing of water and alcohol.

How accurate is True Proof?

True Proof supports various units for concentration (proof, ABV, density), temperature (°F or °C), and abundance (US gallon, liter, pound, kg, US ton, metric tonne), catering to both US and international users.

What is the reference temperature in True Proof?

The reference temperature in True Proof can be set to US standard (60ºF), international standard (20ºC), or any value between -20ºC and 40ºC. It also allows selection of instrument thermal expansivity.

What devices is True Proof compatible with?
