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

The Pro version removes all limits — add unlimited locations, collections and GPS recordings. Travel Diary is your personal journey companion — an app that helps you record, organise and relive every adventure, whether it happened yesterday, years ago, or is still being planned. SAVE LOCATIONS Capture any place with a single tap. Add photos, videos, audio recordings and notes. Rate locations, assign categories and attach them to collections. Every location is stored privately on your device. RECORD GPS ROUTES Start a GPS recording and Travel Diary tracks your route in the background — whether you're walking, cycling or driving. Routes are saved with start and end markers, distance and elevation data. EXPLORE NEARBY From any saved location, tap Explore to discover what's around it — restaurants, museums, nature reserves, hotels, parks and more. Choose a category and search radius, then open results directly in Google Maps or Street View. LIVE WEATHER Check the current weather and a 6-hour rain forecast for any saved location, anywhere in the world — powered by Open-Meteo. COLLECTIONS & GROUPS Organise your locations into collections and group collections by trip, region or theme. Add custom emoji and templates to give each collection its own character. PLAN YOUR TRIP Create trip preparation checklists with tasks, deadlines and priorities. Link checklists to your collections so everything stays in one place. MAP All your locations appear as colour-coded pins on an interactive map. Search for addresses and points of interest, switch between map layers including satellite and topographic, and add new locations with a long press. SYNC & BACKUP Optionally sync your collections to your own website. Export and import backups to keep your data safe or transfer it to another device. NO ACCOUNT REQUIRED Travel Diary works completely offline and requires no account or subscription. Your data stays on your device.

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.
