RostMaster: Coffee Journal

RoastMaster is a precision brewing companion built for coffee enthusiasts who treat every cup like a science experiment. Whether you're pulling a pour-over, running an AeroPress, or dialing in a Chemex, this app helps you capture the exact variables behind your best brews - and repeat them.

Start with the guided brew timer. Follow each stage of your pour-over step by step: bloom, first pour, second pour, total time. A visual progress bar and sound cues keep you on pace, so you can focus on the pour instead of watching the clock.

Build your own recipes. Set your brewing method, coffee dose in grams, water volume, and temperature, then save the combination as a recipe you can return to anytime. Every variable is yours to tune - ratio, timing, temperature - until you find the formula that works.

Track your beans. Log origin, region, farm, processing method, and roast date for every bag you open. Know exactly what's on your shelf and when it's time to restock.

Save your grinder settings. Every grinder has its own scale of clicks, and RoastMaster lets you store presets so you're never guessing what setting produced your favorite cup. Run a proper cupping. Use the interactive flavor wheel to score acidity, body, sweetness, and aftertaste after every brew. Build a tasting record that actually means something over time. See what's working. The analytics screen charts how flavor shifts with temperature and extraction time, so you can spot patterns across your brews instead of relying on memory. Keep an archive of your best experiments - the recipes worth repeating, organized and ready whenever you need them.

Switch units anytime: grams or ounces, Celsius or Fahrenheit. RoastMaster doesn't tell you how to make coffee. It gives you the tools to understand your own brewing process - and get better, one cup at a time.
