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.

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.

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!
I recommend this app to all my friends

It has been a while since I have used this app as I have been doing a Gabi Master A instead of a more traditional dripper. For pour over. But I am in Puebla Mexico, and having some amazing coffee at specialty coffee shops here, and I was showing the app to one of the baristas. And that is how I discovered the subtle changes. But I quickly realize that all I needed to do was to click the PRO option, and all of the details I would need for programming would be there. I learned the app very quickly, and am very pleased with it still and I highly recommend it. It is worth the price. If you are a coffee aficionado like I am.
Easy to use & worth the $2 upgrade!

I’ve tried several pour-over brewing apps and this one is the easiest & most pleasant to use. The method itself is giving me great results, and I love that I can set one number & two preferences and the math & steps are laid out for me to follow. Paid for the one-time Pro upgrade & it’s worth it to be able to adjust ratios. I also appreciate that there’s a 3 second countdown after hitting start so I have a chance to grab my kettle. Only thing I’d like that this app doesn’t have (yet?) is a way to save a short history of my brew sessions. The average drawn down is good info to have but I’d like to be able to refer back to it later.

Thanks for the review! A brew log has been something I’ve considered adding since the beginning. So it’s very likely to come in a future update.
Easy to use Hario method for beginners
The Mac Pro
Really helpful with a small hario to make a cup or two of coffee with a good method that extracts the right flavors you’re looking for. Really good tool for beginners who want to use a hario but are worried about all the different brewing techniques. Start from here, and you just adjust your coffee beans and grind size. I like a very coarse, pretty much like a French Press grind size. Grind 30 on an Encore. Start from here, master this with your Hario, then you always have a standard to come back to while you experiment with other pouring techniques that suit you, while still getting the cup of coffee that you enjoy.
- The "Rings" timer face now shows the previous step alongside the current and upcoming ones, so you can always see where you've been in the brew.
- Total brew time is now tracked independently from individual step times. Pausing or navigating between steps no longer affects the total time, and the accurate total is now saved with your brew notes.
- Timer start countdown animations now respect the Reduce Motion accessibility setting.
- Improved performance, made some UI refinements, and fixed some bugs
