CoffeX walks you through the brew step by step — target weight, timing, and one concrete fix for next time. Thirty-five recipes, from a classic V60 to Ethiopian jebena buna.
Requires iOS 18 or later. No purchases, no subscriptions, no ads.
No mockups — these are screenshots of the app running, with a real bag on the shelf and a real brew in progress.
Most brew timers count seconds. CoffeX knows what should be happening at each of them — how much water should be on the scale, when to stir, when to wait.
Every recipe rescales to your dose with one slider. Water and step targets follow; timings stay, because they come from the brewer, not the amount of coffee.
One step at a time, with the target weight in front of you and a buzz when it changes. The countdown works off timestamps, so it stays honest after you lock the screen.
Sour? Grind two clicks finer. Bitter? Three degrees cooler. The advice is specific to the method you just used, and it lands in your journal.
Milligrams per cup and per day, worked out from the method and the dose. The single most asked question about coffee, answered without a search.
Days since roast, the 7-to-21-day window for filter, and grams subtracted automatically after each brew.
Everything runs on the phone. A cold brew started tonight is still counting tomorrow morning, app closed or not.
Most brewing apps stop at V60, AeroPress and espresso. CoffeX carries the traditions that most of the world actually drinks — with the proportions and the reasons behind them.
Jebena Buna served in three rounds, Café Touba with grains of Selim, Moroccan spiced coffee.
Qishr brewed from the cherry husk rather than the bean, and ahwa with cardamom.
Phin filter, cà phê sữa đá, South Indian kaapi with chicory, kopi tubruk, yuanyang.
Café de olla with piloncillo, café cubano with hand-whipped espuma, coado, tinto.
In autumn the app leads with spiced caramel, gingerbread and maple cold brew. The selection is served as a small JSON file, so the line-up changes without a new release — and it falls back to a season picked on the device when there is no connection.
There is no account, no login and no analytics. Your brews, ratings and coffee shelf are stored on the device and never uploaded. The app makes exactly one network request: it downloads the seasonal recipe list. Nothing is sent with it.
