Pour over coffee made simple

Features & Capabilities

FourSix makes pour-over brewing simple by turning a complex method into an easy, repeatable process. Built around the 4:6 technique from Tetsu Kasuya, it creates a custom pulse pour recipe from three questions: Do you prefer sweeter or brighter profiles? How much coffee extraction do you want? And what size are you brewing? The app shows how each pulse affects your cup and guides you with a precise timer.

When you’re ready, start the timer and pour exactly as instructed. FourSix supports Hario V60 setups with a gram-scale, and it can pair with a gooseneck kettle and thermometer to dial in water temperature. For even more control, FourSix Pro adds extra settings, brew logging with notes and ratings, and notifications about when your coffee is at the perfect temperature.

User Reviews

FourSix Coffee Timer is highly praised for automating 4:6 math, precise timing, ease of use, brew consistency, and notes tracking. Reviewers repeatedly mention the accurate calculations, reliable timer, and intuitive UI as major strengths. A recurring concern is the v2 redesign, which introduced onboarding friction and needed extra taps to access pro features. Overall, it’s a strong tool for pour-over enthusiasts, though onboarding and design changes can slow new users.

Pros

Instant calculations and automatic math for the 4:6 method, making complex brew math effortless.
Built-in timer with precise pour timing and water addition guidance for consistency.
Easy-to-use, clean, and purposeful UI with no unnecessary frills.
Helps achieve consistent, repeatable brews across sessions.
Notes and tracking for different coffees, bags, and brew settings.

Cons

V2 redesign caused initial confusion and added friction (defaulting to brew mode and requiring extra taps to access pro features).

Based on your prompt, here is a polished version of the review you can use for the app store. I’ve structured it to highlight how the app translates complex coffee theory into practical skills. ## Master the 4:6 Method with Ease! ★★★★★ **The ultimate companion for your morning brew.** This coffee app has increased my brew skills and coffee knowledge by tenfold! Before using this, trying to track the math and timing for Tetsu Kasuya’s 4:6 method was a headache, but this app makes it completely effortless. **What I love:** * **Instant Calculations:** You just pick your coffee weight and flavor preference (sweet vs. bright), and it handles all the math for the 4:6 split automatically. * **Perfect Timing:** The built-in timer tells you exactly when to pour and how much water to add, which has made my consistency skyrocket. * **Worth Every Penny:** This app is absolutely worth the money I spent on it. It’s rare to find a tool that actually makes you better at your hobby this quickly. If you’re serious about pour-over and want to dial in your brews like a pro, get this app—you won’t regret it! Since you've been using the app to master the 4:6 method, have you started keeping notes on your different coffee bags in the app, or are you mostly using it for the timer and ratio help?
