What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Stop choosing between portrait and landscape. CreatorCam records both simultaneously — one tap, two perfectly synced video files saved directly to your Photos library. Whether you're filming for TikTok, Instagram Reels, YouTube, or a client project, you shouldn't have to shoot twice or crop later and lose quality. CreatorCam uses your iPhone's dual camera system to capture full-resolution portrait (9:16) and landscape (16:9) video at the same time, from the same moment, with matching color and exposure. DUAL-CAMERA RECORDING Record simultaneous portrait and landscape video using your iPhone's wide and ultra-wide lenses. Both files are full resolution — not crops of each other. SINGLE-CAMERA MODE Switch to single-lens recording with full front camera support. Perfect for talking-head content, interviews, and selfie-style video. PROFESSIONAL QUALITY - 4K and 1080p resolution - 24, 30, and 60 fps frame rates - 2x optical zoom - Tap-to-focus on any object - MOV and MP4 file format options - GPU-accelerated processing pipeline DESIGNED FOR CREATORS - Real-time floating preview so you can frame both formats while recording - Countdown timer (3s / 10s) for hands-free start - Torch control for low-light rear camera recording - Keeps recording through incoming calls — never lose a take - Files save instantly to your Photos library — no export step, no separate app folder BUILT WITH CARE - No ads, no tracking, no accounts - No subscriptions — pay once, own it forever - Your footage never leaves your device CreatorCam is built by a creator who was tired of filming everything twice. Every feature exists because it solves a real problem in real content workflows. Requires iPhone XS or newer with dual rear cameras for dual-lens mode. Single-camera mode works on all supported iPhones.

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