Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Differentiate and validate
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description
CINEMA 24 — Cinematic Camera & Film Filters Turn your iPhone into a cinematic camera. CINEMA 24 brings professional-grade filmmaking to your pocket. Shoot with the depth and atmosphere of classic cinema — real-time color grading, Hollywood-style transitions, and stunning visual effects, all rendered live as you record. REAL-TIME FILM LOOKS Choose from 10 handcrafted film color grades — from the warm tones of Amy and Claire to the timeless grain of Print Film. Every filter is applied in real time, so what you see in the viewfinder is exactly what gets recorded. CINEMATIC TRANSITIONS Cut between scenes with 14 built-in cinematic transitions. Pause mid-shot, trigger a transition, and resume — seamlessly blending clips with the elegance of a film edit. 22 VISUAL EFFECTS Add creative texture to your footage with 22 GPU-powered visual effects — light leaks, lens flares, film grain, rainbow flares, and more. Stack effects with color grades for a fully composed look. HEADCAM — HANDS-FREE FRAMING Stay perfectly in frame, hands-free. HeadCam uses on-device AI to track your face and stabilize the frame around you — ideal for vlogs, selfies, and solo shoots. MULTI-CAMERA MODES HD Mode — Switch instantly between ultrawide, wide, tele, and 5x lenses with one tap. Dual Mode — Record two cameras simultaneously in split-screen or picture-in-picture. Triple Mode — Compose with three lenses at once for dynamic multi-angle footage. SMOOTHZOOM Natural, fluid zoom that accelerates and decelerates like a real lens pull. No sudden jumps — just cinematic motion. PROFESSIONAL RECORDING Record in HEVC up to 4K. Pause and resume without cutting — every segment stitches seamlessly into one file. Save directly to your photo library or export for editing.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
