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.

Your collection is worth more than you think. PopAlpha tells you exactly how much — instantly. Point your camera at a Pokémon card and get an honest market price in seconds. Add it to your collection in a tap and watch your portfolio's value move in real time. WHAT YOU CAN DO • A deep catalog — 45,000+ Pokémon cards across 440+ sets, English and Japanese. • Instant scans — point, shoot, identified in seconds. Works offline, too. • Bulk scanning — rip through a whole stack in one sitting. • AI Grade Check — measure a card's centering, see the grade that centering allows, and find out whether grading is worth the fee. • True graded values — PSA, CGC and BGS priced separately, because a PSA 10 is not a CGC 10. • Japanese cards — priced natively in the Japanese market, not converted from English listings. • Sealed product — booster boxes and packs tracked alongside singles. • Your collection, valued — every card, its total worth, on a live value graph. • Wishlists — save the cards you're hunting and follow their value over time. • Shops near you — find card shops around you on the map. PRICES BUILT TO BE TRUSTED Market Price is deliberately conservative: a blended anchor drawn from real sales, not the highest number we can find. When the market moves, you see that movement as context — not as the headline. It's the number to check before you buy, sell, or trade. ABOUT AI GRADE CHECK Grade Check measures centering from your scan and reports the highest grade that centering alone would allow — a ceiling, not a prediction. Surface, edges and corners still matter, and only a grading company can assign a real grade. If your card can't be measured confidently, we say so, and it doesn't count against your checks. POPALPHA PRO Scanning and collection tracking are free — no subscription required. Pro adds deeper collector insights, live market signals, and price alerts on the cards you care about. • Monthly or yearly • 7-day free trial on yearly PopAlpha is an informational tool, not a financial advisor.

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.
