About

Sip Journal is a finished, live Android app for coffee lovers who want to remember every cup: name what you taste on a 93-note flavour wheel, rate it, link the beans and brew recipe, and see every café on your own map. It has been on Google Play since 14 September 2026 as "Sip Journal: Coffee Tasting", with a matching website.

What you get

• The app: full Flutter source (Dart 3, Riverpod 3, go_router), about 480 unit, widget and golden tests, CI on GitHub Actions, light and dark themes.
• The Google Play app (com.mtgtechnical.sipjournal), moved to your developer account with Play's app transfer, with its store listing, icon, feature graphic and screenshots.
• The backend: Firebase (Auth, Firestore, Crashlytics, App Check) with separate dev and prod projects, and Firestore security rules with their own test suite (96 tests). Everything runs on free tiers.
• The content: the Bean Finder catalogue of 44 specialty coffees (18 of them green coffee lots), 8 brew guides and the flavour wheel data.
• The website (static, on Vercel): landing page, an interactive coffee flavour wheel, a how-to-taste guide, brew guides for 8 methods, a free web tasting journal that makes shareable tasting cards, and the privacy policy and account deletion pages Play requires.
• Brand and design: logo, launcher icon, splash animation, design files for every screen, social post templates.
