Support & Help

Behind Coffee Rings is a developer who's passionate about espresso himself. As a hobby project alongside a full-time job, Coffee Rings was born from my own frustration with notebook chaos.

My promise: I read every message personally and respond as quickly as possible - usually within 24 hours.

User Feedback Makes Coffee Rings Better

Real improvements from real users:

"Too many required fields!"

Feedback: A beta tester found the many required fields overwhelming.

Solution: Step 2 of shot analysis was made optional - skippable for quick results, but available for detailed recipes.

Result: App is more accessible for beginners, but powerful for advanced users.

"I only have a super-automatic"

Feedback: User without portafilter machine felt excluded.

Solution: Espresso Tutor with general knowledge developed and FAQ entry "Optimize what you can" added.

Result: Knowledge is transferable to all brewing methods.

"App should be simpler"

Feedback: Multiple users wanted less complex operation.

Solution: UI simplified, better default values, optional advanced features.

Result: Easier start without losing functionality.

Your idea could be next! Coffee Rings continues to evolve through user feedback.
