The best FourSix alternative for better coffee.
FourSix does one thing neatly: Tetsu Kasuya's 4:6 method on a Hario V60. Filtru gives you that same follow-along calm across fifteen methods, with everything around it.
Available for iPhone and iPad. Free to download.
FourSix Coffee Timer, on the App Store
First, some honesty.
FourSix is a pleasant single-method app: answer three questions and it builds you a 4:6 pulse-pour recipe with a follow-along timer.
And that's the whole app. One method, one brewer, journal behind the Pro purchase, iPhone only, English only. Filtru covers fifteen brew methods, from AeroPress to espresso, with scales, scanning, and a journal built in.

“This is a great app for a beginner. It's helped me get my ratios right for different brewing methods.”— App Store review of Filtru
Why people switch from FourSix to Filtru.
Fifteen methods, not one.
The 4:6 method is lovely. So are AeroPress, Chemex, French press, moka pot, and a well-pulled espresso. Filtru guides all of them with the same step-by-step calm.
The journal isn't an upsell.
FourSix keeps brew records behind Pro. Filtru logs your brews as part of brewing, and the AbolBuna scanner fills in the bag details for you.
Your scale, your graphs.
Connect any of fourteen Bluetooth scale brands and Filtru shows live weight and flow rate, keeping a brew print of every cup.
What you get when you switch.
Guided brewing for fifteen methods
AeroPress, V60, Chemex, French press, espresso, siphon, and more. Each has a baseline recipe and a guided timer that keeps pace with you. See every brew method →
Works with serious coffee scales
Acaia, Timemore, Felicita, Decent, BooKoo and more. Live weight and flow-rate feedback with automatic pairing. See supported scales →
Accessibility is a feature, not a checkbox
Filtru works properly with VoiceOver, including live spoken readouts of your scale's measurements while you brew, as often or as rarely as you like. And you can switch the whole app to fonts like OpenDyslexic, Lexend, or Atkinson Hyperlegible.
