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.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Allow users to input custom foods with sodium values.

Assumption to check: Limited food database for sodium values

Validate with people who use this workflow before building.

Hypothesis 2

Integrate reminder notifications for daily sodium tracking.

Assumption to check: Inability to set reminders for sodium intake

Validate with people who use this workflow before building.

Hypothesis 3

Add social sharing options for users to share their progress.

Assumption to check: No social sharing features

Validate with people who use this workflow before building.

Hypothesis 4

Implement visual graphs to track sodium intake over time.

Assumption to check: Lack of visual graphs for tracking progress

Validate with people who use this workflow before building.

App Store description

Use this app to control sodium and salt intake for lower blood pressure, a lower risk of osteoporosis (high sodium intake increases calcium excretion in the urine), and a lower risk of stomach cancer (excessive salt damages the stomach lining). Set your target daily sodium intake based on guidance provided in the app (or as advised by your healthcare provider) and your preferences for weights of food (g or oz) and display of sodium content in foods and beverages (ie, %target/serving, mg/100g or mg/1oz, or %target/100g or %target/1oz). Record food and beverage consumption using the barcode scanner, dictation or search, or by favoriting foods and using the serving sizes provided (which can be changed at any time). Tap the notepad to add notes. 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 (a sodium/salt conversion tool is provided) and recipes and change serving sizes to personalize 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.  The app also provides nutritional information for many healthy foods and supports a healthy gut microbiome diet using color-coded type and icons.

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.
