Logica Coffee

Brew better coffee for free: guided timers, espresso dial-in, beans, Watch, widgets, caffeine insights and James coaching. No ads, paywalls or subscriptions.

Logica Coffee is the free specialty brewing companion that learns from every cup you make — not generic tips, but coaching built from your own history. No ads, no paywalls, no subscriptions. Optional tips are the only way to support development.

YOUR PERSONAL COFFEE COACH After every brew, your personal coach James reads your rating, technique, and beans — then suggests one clear next adjustment. Try a finer grind for sourness, adjust the ratio, or refine extraction time. No Logica account, no Logica servers. Coaching works offline; optional sync uses your own iCloud.

GUIDED BREW TIMERS FOR EVERY METHOD Step-by-step timing, water targets, and pour cues for V60, Hario Switch, AeroPress, Chemex, French Press, Espresso, Moka Pot, Turkish, Cold Brew, and more. Follow recognized methods such as Hoffmann-style V60 or Kasuya 4:6 — or design your own step by step.

KNOW YOUR BEANS • Scan the bag to auto-fill the basics — name, roaster, origin — and fine-tune the rest • Estimated freshness windows help you brew while each bag is tasting its best • Log tasting notes, star ratings, and structured taste tags — per bag

DIAL IN BETTER ESPRESSO A guided dial-in session walks you through dose, yield, and time across every pull. Logica spots the pattern and suggests your next grind move, so each shot converges on the cup you want.

SEE YOUR PROGRESS Insights surface your best brews, rating trends, most-used methods, and consistency — turning your journal into real, actionable feedback. Track your cost per cup, plus caffeine estimates in weekly context with optional Apple Health logging.

SHARE ANY RECIPE Send a custom recipe with one link or QR code. Anyone with Logica can import it in a tap and brew it immediately.

APPLE WATCH + LOCK SCREEN A full Watch app with synced timer and haptic pour cues. Live Activity follows your brew on the Lock Screen and Dynamic Island — current phase, elapsed time, next pour — without opening the app. A Home Screen widget keeps your favourite recipe a glance away.

PRIVATE BY DESIGN No account. No tracking. No Logica servers. No ads. No paywalls. No subscriptions. Your data stays on your device and syncs only through your own iCloud. Full backup and restore — plus portable JSON export — mean you're never locked in.

Start with one recipe, one bag, or one espresso shot. Logica grows into your private brewing notebook as you brew.
