Generating… usually about a minute.
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.

Lit Cam 2.0 coming soon — fully rebuilt, new modes, free for current users! Turn your device into a light-powered camera, with full control of both the screen and the rear flash. Illuminate subjects at night, zoom-in for sharp macro shots and add a natural glow when taking selfies. Lit Cam is the only app that lets you take photos in complete darkness! Light is everything in photography. Flash in other camera apps can be unpredictable and overpower the photo. We transform it into a continuous configurable light, which makes it vastly more useful. Add the perfect amount to highlight your subject and strike the perfect foreground to background balance. Combine light with zoom to improve photo sharpness and capture hard to see details, which is great for close-ups. The app also works as a photo light. Use it to fill shadows and be creative when using another device as the camera. Adding light is key when taking photos at night or in low light situations. Portable photo lighting solutions can cost over $100. Lit Cam provides similar functionality with the devices you already have. Transform that extra phone or tablet into a photo light! Take better photos at night and add some pop to macros / close-ups. Now go light some shots! Features * Use the display or the flash as the light source * Take photos with both front and rear cameras * Flip sides seamlessly, even with the camera on * Supports all built-in lenses, including the ultra-wide on iPhone 11 * Smooth zoom controls for the rear camera * Magnify and illuminate dark objects, great for macro photography * Manual light power control, from 10% to full-power * When using the screen, pick the color temperature for the best look * Auto-select the perfect screen color when using the front camera * View real-time camera shutter speed and ISO sensitivity * Compare field-of-view to DSLR/Mirrorless camera lens with full-frame equivalent focal lengths * Tap to set automatic focus and exposure * Multiple settings to customize app launch * Optional rules of third grid for great composition * Simple, fast, and focused - no bloat * Minimal interface for one-handed use and optimized for all orientations * Instantly turns on when you open the app * Keeps the screen from unexpectedly sleeping * Thoughtfully dims the screen when using flash * Works on iOS devices of all sizes - turn those old phones/tablets into portable lights! Disclaimer: Continued use of the screen or flash may decrease battery life, but you already knew that.

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.
