iPhone
Log every shot and pour over: dose, grind, ratio, temperature and taste. Then see which settings made your best cup. No account, no ads, nothing leaves your phone.
PrecisionBrew is a brew journal for people who taste the difference. Log what you did, rate what came out, and let the app show you which settings made your best cup.
LOG THE WHOLE RECIPE
Bean, method, dose, grind size, water, yield, temperature and brew time. Brewing ratio and beverage ratio calculate themselves as you type. Espresso gets its own fields for pre-infusion and pressure stability. Then rate the result: overall stars plus acidity, body and sweetness, with room for flavor notes, aroma and anything else worth remembering.
Six brewing methods are ready to go: Espresso, Pour Over, French Press, AeroPress, Moka Pot and Cold Brew. Add your own in a couple of taps.
KNOW WHAT IS IN THE BAG
Every bean gets an origin, altitude, roaster, roast level and roast date. A freshness badge tells you at a glance whether it is still resting, in the window, or past its peak. Add the bag weight and the app subtracts every dose you brew, so you know how many grams are left and when you are running low.
SEE WHICH SETTINGS ACTUALLY WON
Once you have a few brews logged, the journal shows your totals: how many brews, your top bean, your favorite method, your average rating, and how your ratings have moved over time. Open any bean and the dial-in charts plot your rating against grind size, dose and brew time, so the combination that keeps scoring highest is impossible to miss.
BREW IT AGAIN
Found a winner? One tap opens a new brew already filled in with those settings, ready to tweak. Search the journal by bean, method, notes or aroma, and filter by bean, method, date or minimum rating when the history gets long.
A TIMER THAT KEEPS COUNTING
Time your pour without leaving the app. The timer stays accurate when you lock the screen or switch away, and when you stop it, one tap logs the brew with the time already filled in.
YOURS, THE WAY YOU WORK
Grams or ounces. Celsius or Fahrenheit. Light, dark, or follow the system. Text scales with your preferred size across the whole app.
PRIVATE BY DESIGN
There is no account and no sign-up. There are no ads and no tracking. There is no third-party code in the app at all, and the app never connects to the internet, because there is nothing to send anywhere. Every bean and every brew lives on your iPhone and travels with your normal device backup. Nothing is collected, because there is no server to collect it.
Log a brew, then another, and let the numbers tell you what your palate already suspects.
