Worth it for the style information
Although this app has not been updated in quite a while it is well worth paying for just to have the information about the beer styles. The match style is really great and then the info and history about each style is invaluable.
I use it every brew. Id love if they could add a refractometer alcohol calculation. But for now it works mostly and provides great service for less than the price of a single pint in most bars.
