How to install 2brew as a PWA
Frequently asked questions about 2brew
What makes 2brew different from a generic kitchen timer?
A generic timer counts down; 2brew encodes the actual brew structure — bloom phase (typically 30-45 seconds with 2-3× coffee weight in water), main pour phases at controlled intervals, total brew time targets per method (V60 typically 2:30-3:30, Chemex 4:00-5:00). It calculates water amounts based on your coffee dose and chosen ratio, and warns when you fall outside the recommended ratio window. For specialty-coffee brewers chasing repeatable extractions, this structure beats counting manually.
Is 2brew free?
Yes — 2brew is free with no signup, no ads, no premium tier. The PWA is a passion project from someone in the specialty coffee community. The trade-off is that it does not have the polish or active development of paid apps like Filtru ($3.99 one-time) or the deep Bluetooth-scale integrations of Acaia Coffee (free app, requires Acaia scale). For pure brew-timing without scale integration, 2brew is enough.
How does 2brew compare to Filtru or Acaia Coffee?
Filtru is the most-polished paid timer on iOS with beautiful UX and a curated method library ($3.99 one-time). Acaia Coffee is free but only valuable if you own an Acaia scale (Pearl, Lunar, $200+) for Bluetooth-synced flow rate tracking. 2brew is the free PWA option that works on any device including Android and Linux desktop, with no scale required. Most home brewers who do not own an Acaia scale find 2brew sufficient.
Can 2brew work offline?
Yes — 2brew is offline-first. The PWA caches the brew method recipes, timers and ratio calculators. You can run a full brew with no network connection. This matters because brewing often happens in kitchens with poor Wi-Fi or on camping trips. The app stores no personal data — there are no synced recipes or accounts, just stateless brew sessions.
Who uses 2brew in production?
2brew is used by home specialty-coffee enthusiasts — the same audience that follows James Hoffmann on YouTube, owns a Hario V60 or Origami Dripper, and weighs both beans and water on a 0.1g scale. It is not used by casual drip-coffee drinkers (an automatic machine is enough) or by professional baristas (they have shop equipment and trained muscle memory). The Reddit r/coffee and r/pourover communities recommend it alongside Filtru and the Hario V60 official timer.
Where 2brew is heading (12-24 months)
- →Web Bluetooth integration with consumer scales (Acaia Pearl S, Felicita) would close the gap with Acaia Coffee.
- →Community recipe sharing (export a brew profile as a JSON / URL) would create a network-effect layer over the timer.
- →AI-based 'taste tuner' (input how your coffee tasted, get next-brew adjustments) is an unfilled product gap.
