What's New in Spiritulator

3.0

April 4, 2017

This app has been updated by Apple to display the Apple Watch app icon. This version accounts for the volumetric contraction of alcohol/water solutions. Calculations are based on density values at 20 degrees Celsius from the International Alcoholometric Tables - OIML. Results are approximate values only, but are significantly more accurate than the standard dilutions equations used in previous versions. Care should be taken to prevent over-dilution of your spirits.

Useless

Not user friendly

Response from developer

Please specify why it’s useless and not user friendly. All others have rated it 5 stars. Do you have experience diluting distilled spirits? Please let me know how to improve. Thanks.

Work like a charm

Colors a bit trippy, but it does what it supposed to 👍😉

Now accurate for small volumes too!

Thanks for the update!! The additional 2 decimals make this app perfect for the brew hobbyist. Thanks for listening and responding with this update !!!

Happy to change my rating to 5 stars!!!

Previously:
App rounds to only one decimal point, fine if you are dealing with hundreds of gallons or liters, but not accurate enough when working with volumes of less than 1 liter or gallon. Example: this app says to add 400 ml to 700 ml of 76% ABV to create a 50% solution. That would actually yield a 47.8% solution. Correct answer would be to add 364 ml.
An easy fix would be to change the App calculation to 3 decimal points.

Just what I needed

It's a simple little utility that will certainly make your life easier when you're cutting your distillate.

Great App

Very handy when you need to dilute your spirits. I always had to do it by hand or use an Internet calculator. A lot easier and more convenient now. Thanks!
