What is Reddit's opinion of Brew Buddy?

From 3.5 billion Reddit comments

I prefer using Sean terrils calculator as he actually shows data behind his formulas and how accurate they are to other hydrometer readings. I also incorporated his formula into my Android app. If you have an Android devices I've made his calculator portable.

Regarding Sean terrils calculator, I've implemented his using the formulas he's posted on his website in my Android app called Brew Buddy. Simple easy to use and not overly complicated.

Buddy of mine made an app. I think it works great for what I need. Thanks to /u/CUB4N for the app.
