Not a bad app but needs some work. Being able to calculate final ABV would be nice. I find myself having to still google that even though I got this app which seems like a simple thing to add. SG to brix converts would be good too.

Great app, but be careful if you are using any other form of SO2 addition other then KMBS (Potassium Meta-Bisulphite), because the app assumes you are adding a SO2 using a standard powdered KMBS product that contains 57.6% SO2/gram. For example, the Effervescent KMBS from Enartis contains 100% SO2/gram, so if you were using that product then you would be adding too much SO2 using this app.

I've downloaded quite a few of these winemaking apps but this is the first one that I've been really pleased with for the money. It is exceptionally easy to use and covers all the big items for winemaking (SO2 additions, chaptalization/watering back, Brix calculation and acid calcs/adjustment). Plus, I REALLY like the metric/conversion tab and customizable settings.

Not the snazziest UI, but an effective tool. Has essentially all the calculations that I need while making wine. Especially love how easy it makes scaling down from the recommendation for the big boys to my 6 gallon carboys.
