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

Letter Quiz is the best way to learn the English Alphabet with over 10,000 copies being purchased by schools. Four different games for every stage of learning; flashcards, identification, matching and handwriting. Designed for kids but great for all ages. - What People Are Saying: "I think this Letter Quiz is an awesome app. I downloaded the free version and my son was begging for the full version. That's when you know its a good one. So I downloaded the full version and he worked on his letters for an hour. As a parent, I am so happy that he loves it and he is learning." "My 2 year old daughter loves this app. Initially the app had only recognizing the alphabets now it also features writing. My daughter didn't have any interest to write alphabets on paper but when she saw the app, she learned to write in a few days. On the whole excellent app recommend the full version to all parents with little children." Four great games to develop your skills: - ABC Flashcards to get started recognizing letters The uppercase and lowercase versions of each letter is shown on a card. Tapping on the card flips it over to reveal an object starting with the letter while a voice announces the letter and the objects. Use app settings to play in random order for a change of pace. - Letter Identification to test knowledge Multiple letters are shown on the screen and a voice requests you to touch a specific letter. If you touch the right letter, an object is shown starting with that letter, then it moves to the next letter. Get through all 26 letters and you win! Use app settings to play in random order or hide the hints to make the game more difficult. - Matching uppercase and lowercase letters The top shows letters in uppercase. The bottom shows letters in lowercase. Draw a line between the two letters matching uppercase and lowercase to get to the next level. Enable random order in app settings for even more challenge. - Alphabet Tracing to practice handwriting Each letter is presented full screen with dotted lines shown to guide you through writing the letter. As you trace with your finger, fun sounds play along the line. After each letter is finished they are combined on a blackboard with your full alphabet. You can choose between uppercase and lowercase letters or play in random order by enabling them in the app settings. Complete all 26 letters to unlock the fireworks celebration with exploding letters and music! Special Features: - Universal app plays natively on iPad, iPhone and iPod Touch - Kid protected section for adjusting settings, no external links without a parent - Includes both Uppercase and Lowercase letters, enabled in settings - Localized for US and non US pronunciation for the letter Z ("zed" vs "zee") - Teacher mode allows parents to pick individual letters to trace, enabled in settings - Disable swiping to advance Flashcards for younger players Connect with us for feature suggestions or bug reports: On the web: http://TantrumApps.com/contact On Facebook: http://facebook.com/TantrumApps On Twitter: http://twitter.com/TantrumApps

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.
