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

Hey guys! バイリンガールのちかです! 私はYouTubeで「バイリンガール英会話」というチャンネルを通して楽しく英語に触れられる動画を配信しています。 海外旅行で英語で話す時って「なんて言えばよいのか?」「発音合ってるかな…」など、ドキドキしますよね。そんな時に、テキストと音声で英語のフレーズを確認できるのが、このアプリ。 空港やホテル、レストランなど11つのシチュエーションごとに分類して、1000個以上の英会話フレーズを紹介しています!音声は、私・吉田ちかのの声で収録しているので、YouTubeで馴染みのある声で聴くことができてちょっと安心?! 音声は3段階のスピードで聴くことができます。ちなみに、機械的に3段階にしているのではなく、私が「Slow」「Normal」「Fast」をそれぞれ実際に言って録音しています。 音声はオフラインでも聴くことができるので、Wi-Fiなどの環境がなくても大丈夫!海外に行って使いたいのにWi-Fiがないからいざという時に使えない!なんてことはありません。 さらに、シチュエーションごとによくある会話のセリフを動画で確認ができるようにしています。 リアルな会話が繰り広げられる「バイリンガール英会話」の動画もその場で視聴できるので、海外にいなくてもその雰囲気を味わいながら、フレーズを練習できます。 また多くリクエストいただいたフレーズの聞き流し機能も加わったので、連続でフレーズを聞くことができます。 さらに他の言い回しや海外旅行のTipsなどを知ることが書籍「HELP me TRAVEL 旅が100倍楽しくなる英会話」(実業之日本社)も発売中です。こちらの本では、フレーズに加えて、私が今まで体験してきたリアルな会話、そして旅のTipsなどをシェアしています。 このアプリと書籍によって、皆さんが海外旅行に行った時、『勇気を出して話してみたら通じた!』『事前に知っていたから相手の言っていることが分かった!』など、素敵な思い出を作ることが出来たら私も嬉しいです! 海外に行く予定がある方はもちろんのこと、海外に行って英語でコミュニケーションをとってみたい!と思う方は、ぜひ利用してみて下さい!

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.
