The best Act Four alternative for better coffee.
Act Four teaches an espresso workflow. Filtru is the whole brewing companion, still shipping updates: espresso tools, fourteen scale brands, live graphs, and a bag scanner.
Available for iPhone and iPad. Free to download.
Act Four, on the App Store
First, some honesty.
Act Four's video-guided espresso lessons are a pleasant way to learn the pro workflow.
It's espresso-only, hasn't been updated since August 2024, advertises no journal, no scale brands, no graphs, and its smart-home integration is a separate £19.99 purchase. Filtru covers espresso and fourteen more methods, and it's still very much alive.

Two years without an update.
Act Four last shipped in August 2024. Filtru ships every year, and its 4.8 stars come from 11,914 ratings rather than two.
Real scale support, included.
Filtru pairs with fourteen Bluetooth scale brands out of the box. No £19.99 add-on required.
What you get when you switch.
The full espresso toolkit
Dial-in, shot recording, extraction calculator, TDS, plus guided espresso recipes for when you'd rather just make coffee. See the espresso tools →
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 →
