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

Keto or not? Point at the barcode and know before it goes in the cart. Keto Barcode Scan reads the label for you: it works out the net carbs, gives the product a 1–5 star rating and flags hidden sugars and additives. No small print, no math in the aisle. HOW IT WORKS 1. Open the app and point at the barcode. 2. In a second you get net carbs, sugars, fat, protein and calories per 100 g. 3. The stars tell you if it fits: 5 is keto without a doubt, 1 is better left on the shelf. WHAT IT DOES • Keto rating: 1 to 5 stars based on net carbs, with penalties for sugars and sweeteners. • Additives at a glance: colorants, preservatives and sweeteners (E-numbers) grouped by type. • Your own limits: set how many grams of carbs earn 5, 4, 3 or 2 stars. Your keto, your rules. • Discover: what other users are scanning, including in your country, filtered by stars, with side-by-side comparison of two products. • Search: over 3 million products from Open Food Facts, no scanning needed. • History and favorites: every scan is saved; mark, compare and delete as you like. • Backup: export your scans to a file and import them on another iPhone. • 9 languages: English, Spanish, German, French, Italian, Dutch, Portuguese, Polish and Russian. It follows your iPhone's language. NO SUBSCRIPTION, NO ADS, NO ACCOUNT Pay once and it is yours for good, updates included. Your scans stay on your iPhone. Nutrition data from Open Food Facts (openfoodfacts.org) and USDA FoodData Central. The rating is a guide and does not replace advice from a health professional.

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

Implement a community-driven database where users can contribute products.

Assumption to check: Limited product database

Validate with people who use this workflow before building.

Hypothesis 2

Integrate AI for better scanning accuracy.

Assumption to check: Manual barcode scanning can be inaccurate

Validate with people who use this workflow before building.

Hypothesis 3

Offer a free trial and clear value proposition for premium features.

Assumption to check: Subscription fatigue from multiple apps

Validate with people who use this workflow before building.

Hypothesis 4

Add meal planning functionality to enhance user engagement.

Assumption to check: Lack of meal planning features

Validate with people who use this workflow before building.

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.
