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.

Dual Shot Recorder captures vertical and horizontal video at the same time — completely free, no limits. Hit record once and get two perfectly synced files saved to your phone. One for TikTok, one for YouTube. Done. STOP FILMING TWICE Every creator knows the problem. You nail the perfect shot in landscape for YouTube. Then you realize you need a vertical version for TikTok, Instagram Reels, or YouTube Shorts. So you set up again, try to recreate the moment — and it's never quite the same. Dual Shot Recorder fixes this. One tap, two cameras, two independent video files. No reshooting. No awkward cropping in post. No AI reframing that chops off your subject. Just two clean, natively framed recordings from a single take. HOW IT WORKS 1. Open the app and pick your camera setup 2. Choose your resolution and frame rate 3. Tap record — both portrait (9:16) and landscape (16:9) start capturing 4. Stop recording — two synced videos save to your gallery 5. Upload each to its platform That's it. No accounts, no sign-ups, no complicated settings. TWO REAL FILES, NOT A GIMMICK Most dual-camera apps give you a picture-in-picture composite or a split-screen video. That's not what creators need. You need two separate, full-quality video files — each properly framed for its platform. Dual Shot Recorder delivers exactly that. WHAT YOU GET • Simultaneous dual-camera recording — 9:16 and 16:9 in one take • Dual-lens mode using wide and ultra-wide rear cameras • Single-lens mode with front or back camera • 4K and 1080p resolution • 24, 30, and 60 fps frame rates • Real-time storage estimate MADE FOR CREATORS WHO POST EVERYWHERE Whether you make content for TikTok, Instagram Reels, YouTube Shorts, long-form YouTube, or all of the above — Dual Shot Recorder means every take gives you every format. Perfect for vloggers, filmmakers, interviewers, educators, and anyone tired of choosing between vertical and horizontal. YOUR FOOTAGE STAYS YOURS No accounts. No cloud uploads. No analytics. All video is recorded and stored locally on your device. Download Dual Shot Recorder and never miss the vertical shot again.

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.
