I bought the 99 cent app and it looks like it has some useful stuff.
The hops list is nicely up to date, that will be very useful. I will also use the Plato-SG conversion since my refrac only reads in P. Strike temp calculator will also see use for every batch.
The carbonation by style list is limited. I’d also like a temp vs CO2 pressure list for keg carbonation. American is misspelled on the style carbonation list.
Basically you gathered most of the calculators from the green bay rackers, mr malty and tastybrew sites in one portable place. Thats handy. The biggest down side is that I have to wear reading glasses to see my iphone.
The only other thing I use with any frequency is the “can I mash it?” calculator that tell you how much volume a certain mash will take up. I’m always pushing the volume limits of my MLTs.
Overall I like it. Haven’t gotten very into it yet, but from what I see your app has taken about 3-4 other apps I have and combined them into one. Very cool! Should be a help on brew day… which will hopefully be this Saturday or Sunday. I’ll write a nice review afterwards.
