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.

Steporia turns everyday walking into a small daily ritual. Each active day brings one egg. It stirs as you walk: dormant, then glowing, then cracking. When you are ready, three taps open it and a Gozu appears: an elemental creature of Fire, Earth, Wind, Water, or Lightning, pressed onto a holographic Gozu Card in your Dex. WALK TO OPEN MORE The step ladder is fixed and the same for every player. Uncommon opens at 2,501 steps, Rare at 5,001, Epic at 7,501, and at 10,000 steps the full rarity-element matrix is open. A quieter day still keeps your egg. It resolves as a Common Gozu, with an element just as likely as any other. MEET 50 GOZIES Fifty Gozies wait across five rarities and five elements, ten per element. A Gozu you have not met yet carries twice the selection weight of one you already own, so your Dex fills a little faster than chance alone. Duplicates group as quantities. YOUR DEX Filter by rarity or by element. Every card is holographic, with foil that deepens as rarity climbs, and a sigil, accent, and atmosphere that name each element without relying on color alone. TREND Look back over this week, last week, last month, or the year so far. Each period reports the steps you walked, your average day, and how the total compares against the period before it, alongside the ground you covered, the energy you burned, and the Gozies those days produced. The best of them are laid out as a hand of cards with the scarcest in the middle, so a longer stretch turns up rarer things rather than simply more of them. A GENTLE STREAK Set your own daily goal. Consecutive days that meet it improve the odds of the best rarity that day has already opened. Miss a day and the bonus resets. It never takes a Gozu away, and it never changes a hatch you have already seen. PRIVACY Steporia reads your step count, walking and running distance, and active energy from Apple Health, and writes nothing back to it. Your collection lives on your device, with an optional backup to your own iCloud through Steporia Pro. No account, no ads, and it works offline. Reduce Motion and VoiceOver are supported. Walk. Hatch. Collect. PAID ONCE, PRO OPTIONAL Steporia is a one-time purchase, and every feature is included with it. Steporia Pro is an optional auto-renewing subscription that adds two Extra Eggs on each day it is active and backs up your collection to your private iCloud. Restoring a backup never needs Pro.

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.
Not assessed in a Build Kit yet.
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.
