My wife got a gooseneck kettle for Christmas and went deep into pour-over coffee. After watching her Google ratios and water temps for the hundredth time, I figured I’d just build her an app. One Saturday afternoon with Claude Code (Opus 4.5) later, PourCraft was live in the App Store. I’ve been building iOS apps for 12+ years (my other app TravelTimes has been in the store since 2014). What used to take me weeks now takes hours. The key insight I keep coming back to: Specs beat vibes. I didn’t just say “make me a coffee app.” I gave Claude Code detailed specs: exact color palettes, file structure, MVVM architecture, roast-specific brewing ratios (light 1:17, medium 1:16, dark 1:15), the whole thing. Claude Code generated clean SwiftUI with proper architecture, not throwaway prototype code. What the app does: Pick your roast level, then get precise water/coffee ratios using the Golden Ratio Step-by-step brew guide with temperature guidance (F° and C°) 8 expandable pro tips on grind size, spiral pouring technique, water quality Dark mode with a coffee-inspired design Free, no ads, no tracking The real win? My wife uses it every morning. She still corrects my technique though. I wrote up the full story (the prompting strategy, what worked, what I’d do differently) on my blog: Vibe Coding with Coffee The app is free on the App Store . The full source code and the prompt I used are on GitHub . Would love to hear what other “scratching my own itch” projects people have built with Claude Code. submitted by /u/vscarpenter
