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
This app requires an iOS device with FaceID (uses your face to unlock the device)! See the full list of devices at the bottom of this description. SEE IN THE DARK With the LiDAR & Infrared Night Vision app, you can use the front camera on devices with FaceID, and the front and back cameras on iPhone 12 Pro, iPad Pro, iPhone 13 Pro, and iPhone 13 Pro Max in complete darkness! The front-facing camera will use the infrared sensor in the TrueDepth camera. The rear-facing camera will use the new LiDAR sensor. The LiDAR & Infrared Night Vision app turns the world around you into a depth map, where different colors represent distances from your device. SCARE YOUR FRIENDS Trigger scare-mode and set your friends up for a huge scream. For best results, be in complete darkness in a room with space behind you. Explain to your friends how the cool new app shows things around the room you can’t see with the naked eye. Make sure your friend’s face is on the screen, and after 30 seconds, a jump-scare flashes on screen, and captures the terrified face. APPLICATIONS See in the dark without turning on your flashlight Show off your new phone capabilities Scare Your Friends Make Your Friends Cry Share your friend’s terror with a captured picture or video. Explore how LiDAR and infrared technology works Learn about depth maps and seeing without light HOW DOES IT WORK? Unlike a regular camera, LiDAR and infrared sensors do not need ambient light. They both generate their own light, which you cannot see. Therefore, both sensors will work in complete darkness. OTHER DEVICES This app will work on devices that don’t have LiDAR. It will use the front TrueDepth camera to provide a depth map of yourself and objects behind you. The rear-facing display will not work without an iPhone 12 Pro, iPhone 13 Pro, or iPad Pro (4th Generation). Works on any iOS device with FaceID/TrueDepth including: iPhone X, iPhone XS, iphone XS Max, iPhone XR, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12, iPhone 12 Pro, iPhone 12 Mini, iPhone 12 Pro Max, iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max, iPad Pro (3rd generation), iPad Pro (4th generation), iPad Pro 2021

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.
