What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Youth Soccer Coaches Run game day from one app: rosters, lineups, formations, schedules, live playing time, player stats with an assistant Stat Keeper, and shareable reports. TEAMS AND SCHEDULE Create and manage one or more teams. Build each roster with player names, numbers, positions, and photos, and mark players unavailable. Organize your schedule with date, time, location, field number, and home/away status, and see your next game and season record at a glance. LINEUPS AND FORMATIONS For every game, choose a formation template and build as many lineups as you need, assigning players to starter and substitute positions. Change a game's size or default formation any time. Fine-tune each position with the precise x-axis and y-axis alignment tool. GAME DAY Track goals, assists, shots, saves, cards, and more for each player live, and use the built-in stopwatch to keep every player's time on the field. See who is on the field and who is on the bench, and tap a position to open that player's stats. Want a hand? Add a Stat Keeper (below). STAT KEEPER Let one assistant record stats and make substitutions from their own iPhone or iPad during the game, while you stay focused on coaching. Start a session from any game, then have your assistant scan the QR code or type the 4-digit code. It works directly between the two devices, with no internet and no account. Your phone stays the source of truth, and everything your assistant records is saved in your game as it happens. Your assistant sees player cards with photos and jersey numbers, plus the bench, and can take back a stat recorded by mistake. If the connection drops, they keep recording and everything is sent once you're back in range. You choose what your assistant can do and can end the session at any time. Stat Keeper needs a second iPhone or iPad running the app. AI MATCH STORY After the game, generate a personalized recap of your team's effort, written entirely on your device with Apple Intelligence (compatible iPhone or iPad required). Each story includes a scoreboard, Player of the Match, key stats, a goal timeline, and your season record. Customize the story, then share it. SHARE WITH YOUR TEAM AND PARENTS Share images of your lineups, match reports, player reports, schedule, roster, and Team Results (record, form, and stat leaders). FORMATIONS FOR EVERY GAME SIZE Formation templates for 4v4, 5v5, 6v6, 7v7, 8v8, 9v9, 10v10, and 11v11. Light and Dark mode. English, Spanish, and French. No ads. No feature limitations. No subscriptions. This is a one-time purchase. Optionally, you can "Become a Supporter" through an in-app purchase, with tiers including Bronze, Silver, Gold, and Platinum. Becoming a supporter is completely voluntary and never unlocks or restricts any feature of the app. I've been coaching soccer in the U.S. for over 15 years, and many coaches have contributed to developing these formations on my website. You can preview every formation, and watch comprehensive video tutorials, at brantwojack.com/app or on YouTube (search "BW Futbol Formations").

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
