Coffee Corner in your pocket.
The website helps you read, compare, and learn. The app is for the messy part of coffee: remembering what you drank, seeing how much caffeine may still be active, following a timer while water is already boiling, and finding the cleaning step when a machine starts blinking at the worst possible moment.

The daily coffee layer for Coffee Corner readers.
Every module starts from one rule: useful coffee data should be quick enough for a weekday morning and clear enough that you do not need to reread a manual while coffee is getting cold.
Cup log
One-tap coffee history
Log espresso, latte, pour-over, cold brew, pod coffee, or custom drinks with size, time, bean notes, and rating.
Caffeine meter
Know what is still active
Estimate current caffeine, daily total, sleep cutoff, and how a new drink changes the rest of the day.
Brew guides
Recipes that become timers
Use ratio calculators, guided steps, bloom timers, haptics, and finish screens that can log the brewed cup.
Manual search
Machine help without digging
Search setup, cleaning, descaling, troubleshooting, and model notes from the Coffee Corner machine library.
Bean shelf
Remember the bags worth buying again
Save roaster, origin, roast level, tasting notes, brew fit, and your own rating for every coffee you try.
Facts and quiz
A small daily ritual
Daily coffee facts, short quizzes, streaks, and achievements make learning about coffee feel alive.
Build notes
What we are solving first.
The first app should feel like a tool, not another feed. These are the product decisions guiding the launch while the website continues to grow around coffee tools, gear guides, and machine manual search.
One platform, better first version
The first release will stay focused on Android so the logging flow, caffeine math, notifications, haptics, and offline notes can be tested properly before we widen the build.
Machine help has to be searchable
Instead of dumping PDFs into an app, the plan is to index setup, cleaning, descaling, part names, and common troubleshooting notes by model.
Useful estimates, honest limits
The caffeine meter will use editable drink values and a configurable half-life, with clear warnings that biology, medication, pregnancy, and sleep sensitivity can change the real effect.
Website plus app
Read here. Brew there. Keep the loop connected.
The app will connect back to Coffee Corner guides, reviews, calculators, and the growing machine manual search. Start with the caffeine calculator, plan a recipe with the brew ratio calculator, or use the coffee maker quiz while the Android app is being built.
Caffeine estimates are educational approximations, not medical advice. Sensitivity, medication, pregnancy, health conditions, sleep, and serving size can change the real effect.
Build roadmap
