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

There's more to your food than calories. That banana you had for breakfast? It brought along potassium, magnesium, vitamin B6, manganese, and about 50 other nutrients. Most trackers don't mention them. Nibbled does. We track 80+ nutrients for every food you log — vitamins, minerals, amino acids, fatty acids — all from the USDA FoodData Central database. The same data dietitians reference, presented in a way that actually makes sense. Search over 8,000 whole foods, scan barcodes for packaged products, or create your own foods and recipes. Curious which foods in your search have caffeine data? Tap the filter and find out. Sort results by nutrient completeness, calories, or protein to find exactly what you need. Set goals for any nutrient, not just the big four. Pin the ones you care about to your dashboard. Set a flexible "Today Only" goal when your plans change. Watch the little celebrations when you hit a target. If you use Apple Health, Nibbled writes detailed nutrient data for every food you log — food name, meal type, and all. Your Health app will thank you. Organize your meals however works for you. Six templates come built in — from a simple list to Breakfast/Lunch/Dinner to a six-slot Grazing mode. Or build your own. Rename everything. It's your kitchen. Your data stays on your device. Always. We don't collect it, we don't see it, we don't sell it. Export it anytime in Markdown, CSV, JSON, or PDF. Share meal templates with friends. Import your data back if you ever need to. Six color themes come along for the ride. Blackberry Jam for late nights. Lemon Meringue for early mornings. Strawberry Shortcake for whenever you're feeling warm. Switch freely — they're all yours. No subscriptions. No ads. Just good food data, whenever you need it. · 80+ nutrients tracked per food · 8,000+ whole foods from USDA databases · Barcode scanning with USDA fallback · Custom food and recipe builder · Nutrient filters and sort options · Apple HealthKit integration (40+ nutrients) · Six meal templates with full customization · Personal goals for any nutrient with Today Only option · Duplicate, edit, and move entries between days · Four export formats · Six color themes with ambient effects · Home screen and lock screen widgets · VoiceOver and Dynamic Type accessible · Offline-first — works without internet Data sources: USDA FoodData Central (public domain) and Open Food Facts (Open Database License).

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.
