The brew formula. Revealed.

Dialed-in coffee math from a cat who definitely thinks he’s smarter than you. Zero room for mistakes.

Pour when told. Breathe when allowed.

Octave guides you through each phase—bloom, pour, repeat. Try to keep up.

Questions? Seriously?

You’ve got questions. Octave has opinions.

How do I use the app?
icon

Just pick how many cups you want, choose your brew strength, and Octave will calculate the coffee-to-water ratio. Then follow the step-by-step timer to brew with precision (and attitude).

What brewing methods does this support?
icon

This app is built for pour-over coffee. Not espresso. Not cold brew. Definitely not your pod machine. V60, Kalita, Origami, or similar—if you’re pouring, you’re in.

Does Octave actually do anything, or just insult me?
icon

Both. He calculates precise ratios, walks you through each brew step with timers and animations, and occasionally judges you. It’s emotional support… with claws.

Can I change my ratio or grind size?
icon

No grind size settings (yet), but you can adjust strength levels that correspond to common ratios (like 1:15, 1:16, etc.). Octave makes it simple. Because you clearly need simple.

Why is Octave so mean?
icon

He’s not mean. He’s just disappointed. There’s a difference.

Does this work with a drip machine?
icon

No. And how dare you. This app is for people with taste.

Will this help me brew better coffee?
icon

Yes—if you listen. Octave’s not here for your feelings. He’s here for your coffee.

Is Octave a real cat?
icon

He’s real in spirit. And somewhere in a dimension where cats brew coffee and judge humans, he’s thriving.
