Every Tool On The Bar. Free.

Free to join, no card required, and every tool works offline. Open a tool and use it right now.
Twelve Tools. Zero Paywall.
Not a textbook that dumps theory on you — tools that fix one thing at a time and tell you exactly what to change next. Every tool below is free.
Dial-In
Dose in, ratio out — with a taste-based nudge for your next shot.
Cup Cost
What does a latte actually cost you? Price the beans and milk, it does the rest.
Shot Timer
Start the pump, hit go. Log the time straight into your journal.
Espresso Rescue
Shot gone wrong? Sour, bitter or thin — one rescue move at a time.
Milk Guide
Stretch, spin, shine — temperature targets and pour patterns for each drink.
Water
GH/KH targets and remineralisation for filter and espresso.
Pressure Clock
Track pressure through the shot like a pro, not a guesser.
Recipe Lab
Build and compare brew recipes before you touch the grinder.
Grinder Translator
Grind settings that translate between recipes, burrs and machines.
Varieties
Coffee varieties decoded — know what’s in the bag and why it tastes that way.
Taste Log
Train your palate properly — one cup, one note at a time.
KL Coffee Map
Roasters, cafés and cupping rooms around Kuala Lumpur.
All twelve free with your account — no card, ever. Pro is the memory, not the paywall.
Open. Pick A Tool. Pull A Better Shot.
Use the tools free
Every bench tool and the KL coffee map are free, on any phone — even with dead Wi-Fi. Nothing to pay.
Sign up to save your work
The moment you want to keep a dial-in or a costing, a free account holds it. No card, and your tools remember you.
Go Pro to keep the story
Pro is the memory: your coffee journal, KL tastings and the recipes you swap. RM25 a month, optional, cancel anytime.
Every Bag. Every Shot. Remembered.
Stop guessing why yesterday’s shot was better. Saved dial-ins and costings land in your journal automatically — and ten logged shots teach you more than ten watched videos, because the patterns are yours.
- Saved dial-ins — every dose, ratio and grind move you lock in, kept.
- Cup costings — margins per drink, ready when your menu changes.
- Tastings on record — the coffees you try, with what you tasted, build your Coffee CV.
Dead Café Wi-Fi Won’t Stop You.
The bench tools run offline — nothing to install, nothing to update. Roastery basement, market stall, back-of-house on a busy shift — your timer, dial-in and journal keep working.
On the bar
Timer, dial-in and Espresso Rescue stay live through a rush — no connection, no problem.
At the roastery
Log roasts and cuppings where the signal doesn’t reach. Sync when you’re back.
At home
Your journal is yours — every bag and every shot stays on your device, ready when you are.
