Roastafarian is an app for coffee journaling first and foremost. Document, rate, photograph, and share your coffee as you glide through the beautiful User Interface.
Timers and convenience tools are also included in the "Brew" section. Brewing more than one coffee at a time? No problem. Just enter a time, and save your timer. It will then run in the background with all your other saved timers, updating in unison, and informing you when your timer has finished and for which coffee (even if Roastafarian is not the currently active app). It can be especially handy for cold brewing.
Finally the guides section aims to help you brew the best tasting coffee possible. Included are three basic "staple" guides intended for beginners.
