When the weather’s nice, many people find themselves sitting outside a local tavern sampling all manner of tasty ales. If you’ve ever wanted to try your hand at homebrewing, or simply hope to discover great ales and breweries nearby, your Android device is a goldmine. Tap into these helpful apps.

Here’s where things get a bit more sophisticated and complicated, but homebrewers will find this app to be highly useful. Depending on the ingredients you have around, you’ll be able to design beer recipes on the go. It handles all the hard work and tricky mathematical formulations usually required and even includes a timer. It can calculate the OG (original gravity), FG (final gravity), IBU (bitterness), color and the estimated alcohol content of your concoction, supporting both metric and U.S. imperial units.

Admittedly, there are a whole heap of similar apps in Google Play, but Brewzor Calculator covers so many in a single app and has some very positive reviews. It can calculate a lot of complicated, technical things essential for a good homebrewing experience like strike temperature, mash infusion, decoction volume, yeast pitching rate and batch sparge. We would explain what all these mean, but we’re too drunk right now.
