BrewTrail: Coffee Journal

BrewTrail is a small coffee notebook for home espresso and filter brewing. Time a brew, record what you used, and keep the recipe you want to try again.

TIME YOUR BREW
Start, pause and reset a simple brew timer. Timing continues when you switch apps. A running timer can restore after the app is reopened within the same device boot. Logging a brew stops and resets the timer.

REMEMBER YOUR RECIPE
Save beans or roaster, brewing method, coffee dose, liquid weight, total time, grinder setting, tasting notes and a rating. Choose espresso, pour-over, AeroPress, French press or another method.

MAKE RATIOS CLEAR
See the liquid-to-coffee ratio for each saved brew. For espresso, enter beverage yield; for filter coffee, enter brewing water. The quick ratio tool calculates liquid weight from a dose and target ratio.

BREW IT AGAIN
Open a saved brew to reuse its recipe values. Add a fresh tasting note, edit an older note or share a recipe through Android's share sheet.

KEEP YOUR JOURNAL
No sign-in or equipment connection is required. Records stay on your phone and core tools work offline. Export and restore JSON backups through Android's file picker. Backups contain saved brews, not active timer state. Automatic cloud backup is disabled; export before changing devices or uninstalling.

BrewTrail does not connect to Bluetooth scales, predict extraction quality or schedule background alarms. It includes an AdMob banner when an internet connection and permitted ad request are available. There is no subscription or in-app purchase.
