Your coffee log, in your pocket — early
Log a brew while it is still pouring, with a timer and ratio math. Everything syncs to the web. It is a beta, so expect the odd rough edge.
Perco is not on the App Store yet. The beta installs through Apple's TestFlight app, and builds expire after 90 days.
Bean Passport
Every bag you brew becomes a stamp
Each bean mints its own stamp from its name, origin and roast. The same bag makes the same stamp on every device, forever, and a brewed one gets postmarked.

Built by a coffee obsessive who was tired of losing the perfect recipe in a notes app.
Perco started as a personal log for chasing the ideal cup, and grew into the tool serious home brewers actually wanted. No spreadsheets, no forgotten grind settings, no guessing why yesterday tasted better. Just your coffee, understood.
The core is free. The obsession is optional.
Everything you need to log and understand your coffee is free, forever. When you're ready to go deeper, Premium is waiting.
