IMPORTANT Installation Note: The stock numeric keypad on some Samsung and LGE devices does not include a decimal, which makes FermCalc almost impossible to use. The workaround is to go to Google Play and install the Google Keyboard or some other third-party keyboard. After you install the new keyboard, go to Settings > Language and Input, and set the new keyboard as the default keyboard. After following these steps your numeric keypad should include a decimal.

Comments on FermCalc Winemaking Calculator for Android

★★★★☆ Alucard · May 21, 2023
Undecided! Does this help you find a juices value of sugar in grams? After it has been brewed? And with a fractometer? And is it accurate? Also how do you tell how much alcohol is in wine in % with this and a fractometer?
★★★★★ Vinay Rananaware · Jun 30, 2017
The best app. My mate in winemaking. Very useful for an amateur winemaker. Helps you to feel like a professional wine master. Thank you so much. God bless you.
★★★★★ Cody Lent · Oct 1, 2023
Huge help for calculations. So simple to just put in some info and have it calculated without any headache. Love this app!
★★★★☆ Tom Bentley · Apr 30, 2017
Great wine making calculator, and responsive author. Low reputation per Sophos antivirus (see sophos 'how to request an app reassessment')
★☆☆☆☆ Paul Jensen · Sep 7, 2021
Without prejudice, this is the worst wine making calculator I've ever used. If I could have given it a 0.0% Star review rating I would have.
★☆☆☆☆ Kevin Mac · Sep 18, 2016
Where's the decimal? Not sure if it's my phone or me but when the number pad pops up it's only 0-9, no decimal kind of hard to enter SG without one.
