What are the best Android Apps for homebrewing

For BJCP Info, I use BJCP 2015

Beersmith (lite or full) is a good tool (but I tend to do everything on the PC, so I do not use the app that much). The app allows for recipe formulation, logs and timers.

Brew Timer is a life saver for letting you know when to do what. Easy to configure. The pre-warning function is one of the best features.

Lastly, CvPad, for all your conversion needs.

On my phone the only 3 beer-related apps I have installed are:

Jomebrew Beer Stats and Conversions

I grabbed this primarily to convert Brix to SG because my refractometer is in Brix. The interface isn't great, but its a quick simple app for doing some basic conversions. It will also take OG and SG and give you ABV and attenuation. It also does have a timer sections to it where you can set up a few timers for a step mash or boil additions.

Brewer's Friend

I use their website for creating and storing recipes, so grabbed their app too. It is fairly new and has some bugs, but isn't bad for tweaking a recipe here or there, or if I'm out talking to other brewers and someone wants to know what I used in a beer I can look it up.

I think this app also has a brew-day section where it guides you through the recipe and each step, letting you track measurements along the way, but I never use it.

BJCP Droid

Which I mostly just use when tasting or researching, for style guide info.

I'm also a computer programmer and like my share of gadgets, but for me, I like just having a good old fashioned printout of my recipe and a spiral notebook to track my readings, measurements, and tasting notes for each batch.

The only thing I do on my phone on brew day is the brix->SG conversions and timers.
