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

Saturated fat increases LDL "bad" cholesterol and is a cause of many inflammatory diseases through its effect on the immune system. Use this app to lower intake to protect from atherosclerosis, coronary artery disease, stroke, hypertension, type 2 diabetes, obesity, non-alcoholic fatty liver disease (NAFLD), some cancers (esp. bowel, breast, prostate), depression, anxiety, Alzheimer's dementia, Parkinson's disease, bipolar disorder and schizophrenia. Set your daily saturated fat intake based on guidance provided in the app and your preferences for weights of food (g or oz). Record food and beverage consumption using the barcode scanner, dictation, search or by favoriting foods and using the serving sizes provided (which can be changed at any time). Tap the notepad to add notes. Compare the saturated fat content of different foods by tapping the Compare button on the "Foods" screen. Monitor daily and long-term progress, export data to share with healthcare providers, synchronize data with other First Line Medical Communications Ltd nutrient counter apps, and share data with Apple's HealthKit. Add your own foods and recipes and change serving sizes to personalise the app's 400-item database for you. All food and beverage popups indicate whether the item is a plant, good prebiotic, probiotic or ultra-processed food (UPF) to inform a healthy diet and whether they are high or low FODMAP per serving where data are available to support people with irritable bowel syndrome (IBS). Useful lists show saturated fat content of foods per 1oz or 100g and serving, which can be toggled from high to low & low to high. Also useful UPF, unprocessed plant, prebiotic, probiotic, high & low FODMAP food lists.

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.
