Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Contraction Monitor is designed for pregnancy mums to track contractions. Regular contraction is an importance sign of labor, when that big time is approaching, duration of contraction becomes longer and stronger, frequency becomes shorter. And contractions will show their laws when true labor is coming, so keep tracking contractions will help you distinguish true labor from ‘false’ labor. Graph of contraction duration and frequency makes it easy for you to see the tendency of contractions. The operation is very easy, just press the button when contraction starts and press the button again when it ends, Contraction Monitor will log the start time, end time, duration and frequency and intensity of this contraction. Features: ⁃ Log start time, end time, duration, frequency and intensity of contractions. ⁃ Analyze contractions by chart and histogram. ⁃ Calculate the average duration and frequency of latest three, five, ten and all contractions. ⁃ Add note to each contraction. ⁃ Share your contraction data with your doctor or friends by email. ⁃ Continue contraction where you left off in the condition that you make a call or play other apps while logging contraction. ⁃ Calculate your delivery due date, show days remaining to your due date and days passed from your last menstrual period. ⁃ Contact module for you to add your labor contacts, you can call them conveniently by one touch if your baby is coming when you are logging contractions. ⁃ Passcode function to protect your info. ⁃ Supports Touch ID or Face ID as passcode. ⁃ Support edit function for contraction logs. ⁃ Support migrate data from free version. ⁃ No ads. ⁃ Supports Apple Watch version. ⁃ Support both iPhone and iPad version.

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.
