Scanner improvements.

Added controls for auto focus and lens selection in the barcode scanner. This gives you flexibility to see what settings work best for scanning keg barcodes at your brewery. New Brewsheet timers feature that allows you to schedule a notification when it's time for the next step in the brew!

You can now track your brewery's yeast inventory, plus everything else we didn't track before like nutrients, enzymes, cleaning chemicals... all of it (previously we only tracked fermentables and hops). Feel the freedom of the imperial and metric system, and don't be tied to just 1 unit. We now handle conversion between units so you can create purchase orders in pounds, while creating recipes in grams.

Enhanced keg tracking - You can now click a barcode in the Packaged Beer tab to see the keg's transaction history. Scanner Flashlight - Turn on your iPhone flashlight when you need a little extra light when scanning kegs!
