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
Records your talk or snoring while you are asleep (automatic or manual sensitivity level, records only snoring using smart snoring detection), creates the graph of noise in room during the night, takes the total time of snoring down. Snoring detection is based on artificial intelligence (A.I.) with the support of a new Apple machine learning technology. By using a large number of snoring samples, we can achieve high accuracy in statistics and in snoring detection itself. HIGHLIGHTS: - ADJUSTABLE RECORDING SOUND SENSITIVITY: For different sound conditions in your room (a quiet or loud environment). - HIGH TECH SNORING DETECTION: Accurate snoring detection based on A.I. - POSSIBILITY OF RECORDING ONLY SNORING - AUDIO VISUALIZATION DURING RECORDING OR PLAYING - FAVORITE RECORDINGS - SHARING RECORDINGS WITH YOUR FRIENDS: Send recordings via email, iMessage or post to Facebook. - AAC AUDIO COMPRESSION FOR THE BEST RATIO QUALITY AND SIZE - CHART OF NOISE IN THE ROOM DURING THE NIGHT - FACTORS, WAKE UP MOOD, NOTES: User can place factors (alcohol, coffee, stress etc.) to every night as well as the mood after waking up or add own notes. - ACTIVATION DELAY: Starts monitoring after a period of time. - BACKGROUND MODE: Monitoring runs also in background mode. Alarm also fires from background. - APPLE HEALTH INTEGRATION - iCLOUD SYNCHRONIZATION: Synchronization among your devices and between free and paid version. - EXPORTING HISTORY TO CSV FILE - APPLE WATCH: If you buy SMART ALARMS then it will track your sleep movements and it can play haptic (sound, vibration) if alarm is set. If you buy STOP SNORING then it will play haptic (sound, vibration) if snoring is detected. PLEASE NOTE THE FOLLOWING: * It is recommended to connect your iPhone (iPad) to a charger. * Set "Airplane Mode" or "Do Not Disturb" on your iPhone (iPad) for undisturbed sleep. * Place your iPhone (iPad) close to you with the microphone towards your bed. CUSTOMER SUPPORT Happy customers are our highest priority. If you have a problem with our app, please contact us at [email protected].

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.
