Your brew log. Built to last.
Log a brew in under thirty seconds. Dose, water, method, result. Over time, you see what worked, what changed, and why one cup tasted better than the last.
How it works.
Fast to log
The app opens to entry. Scroll pickers for numeric values, no typing numbers on a mobile keyboard. Log a brew before the bloom finishes.
Your history, visible
Brews stack chronologically. Scroll back to any session. Filter by method, bean, rating, or date.
See what works
Across dozens of brews, you spot which parameters correlate with your best cups, and how the same bean changes as it ages.
Your data, portable
Every record uses BrewSpec, an open format. Export anytime. No lock-in.
Built on BrewSpec.
Calibrate stores every brew record in BrewSpec, a free, open data format for coffee. Your data stays yours. Export at any time. Import into any tool that reads the format.
