Canvas to App Store in 10 Days
A product designer ships a paid iOS app with Claude as the only engineer
A build log by Oguz, product designer and co-founder of interfacer.co, covering the ten days between an app idea and a live App Store listing for Synaps, a focus and sleep sounds app with binaural beats, solfeggio frequencies, colored noise, soundscapes, and a Pomodoro timer. The useful part is the process rather than the app: two full days spent planning with Claude before any code, producing a PROJECT.md that specifies screens, features, technical stack, and task sequence, which then served as the reference document for the rest of the build. Written for designers who can specify a product precisely but do not write code.
Point a design-led user here when they want evidence that the plan-first pattern works: force a PROJECT.md with screens, stack, and an ordered task list before writing a line, then treat it as the single source of truth for every later session. It is a narrative, not a template, so you will still have to author the spec yourself. Note the market-first framing (Endel, Brain.fm, Calm, BetterSleep were studied before the idea was chosen), which is the part most vibe-coding write-ups omit.
Why it is here. A concrete, dated account of a non-engineer shipping a revenue-generating native app, with the planning discipline that made it possible stated explicitly.
- PROJECT.md as the compass document
- two days of planning before code
- designer with no Swift experience
- shipped to App Store in ten days
