## What is FourSix Coffee Timer?

FourSix makes brewing pour over coffee easy.

There are countless ways to brew coffee. For coffee enthusiasts, sometimes these methods can get... complicated. And following a more complex recipe can be difficult, especially in the morning when you haven't had your coffee yet.

Part calculator, part timer, FourSix is designed to take a complicated method for pour over and make it simple and easy, even if you're still not completely awake. Named after the 4:6 method invented by Tetsu Kasuya, FourSix will create a custom pulse pour recipe based on 3 simple questions - Do you like your coffee sweeter or brighter? How do much do you want to extract your beans? And what size? Instantly, you'll see how each pulse-pour will break down, and how they affect your final cup. When you're ready to start, simply follow along with the Timer telling you exactly how much to pour and when. Not only will you get a great cup of coffee, but you'll be able to do it again the next morning.

To use FourSix, you'll need a Hario V60 and a scale that measures in grams. Additional helpful tools include a pouring kettle with a narrow spout and a thermometer to test water temperature.

If you like FourSix, but want even more, you'll want FourSix Pro.
- Get extra settings so you can dial in your perfect brew exactly how you like. 
- Record every brew and make notes, ratings, and track your coffee beans. 
- Get notifications about your coffee cooling to the perfect temperature.

### 5/5 — Master the 4:6 Method with Ease!

*2026-05-03*

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?

**Developer response:** I’m choosing to take this review at face value and that the sentiment is genuine and from a real person despite the fact it was written by AI. So thank you for the review!

### 5/5 — My favorite coffee timer!

*2025-11-09, version 2.7.1*

No unnecessary UI frills, to the point and the correct control to make a perfect pour.

### 4/5 — Dynamic Island

*2025-10-27, version 2.7.1*

Can you use the Dynamic Island, so that we can know the pour while we open a different app?

### 5/5 — Love it!

*2025-10-16*

If you want consistent coffee and the ability to keep track of small tweaks without the guesswork, this is the app!

**Developer response:** Thanks for the review!

### 5/5 — Best pour over timer app

*2025-06-05*

If you’re a coffee nerd like me,  this app will be a god send to help you track and brew perfect cups every single morning. Each thoughtful update brings ease and sophistication to my uncaffeinated mornings.

**Developer response:** Thanks so much for the kind review!

### 2/5 — Pushing subscription for features

*2025-06-03, version 2.6.1*

Pushes subscription, upgrade to pro just to use basic timer.  Would be willing to pay upfront for straightforward app

### 5/5 — Lightweight, functional, tweakable

*2025-03-08*

Everything I could ask for. Always happier to support home brew projects than corporate ones. 

If it weren’t for this app I probably could never be bothered to try the 4:6 method.

Also, the developer is an incredibly awesome human being. Went out of their way to accommodate me, despite my objections due to my use case being very narrow.

**Developer response:** Thanks so much for the kind review. Always happy to receive feedback and ideas on where things could be improved. I actually think your use case wasn’t that narrow, as I find myself making small tweaks to the amount of coffee sometimes too. The stepper is definitely ideal for that, so I’m glad you reached out because I think it’s an improvement for everyone!

### 5/5 — Notes Feature is excellent

*2024-09-07*

Have been using this app for a long time now. The notes feature is life changing! haha

**Developer response:** Thanks for the review and for sticking with me for so long 😄

### 5/5 — Simple and straight forward

*2024-07-17*

Simple, concise app, easy repeatability for coffee

**Developer response:** Thanks for the review! Glad to hear you’re enjoying the app.

### 5/5 — Thank you for the great app!

*2024-05-04, version 2.3.2*

I was an early adopter and I’m still using it today!
