Generating… usually about a minute.
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.

ALWAYS UP-TO-DATE GUN LAWS Unlike other apps with outdated information, CCWCalc features the most current gun laws in the App Store. Our proprietary monitoring system automatically detects firearm related changes on websites for: • State statutes • Federal courts • State courts When Minnesota lowered its permit age to 18 due to an 8th Circuit Court ruling and California was forced by a 9th Circuit Court ruling to allow carry on public transit, CCWCalc users knew immediately — while other apps and the NRA website remained outdated for weeks. KEY FEATURES • Save your permit information, military status, age and get a personalized carry map showing exactly which states you can carry in • Permit type precision — for states that only honor enhanced permits from your state, that is reflected in your personalized carry map • Advanced bidirectional reciprocity maps showing exactly which permits are honored in each state, even addressing complicated cases like WI only honoring non-resident permits from FL and VA • Contact info including links for AG offices, state police agencies, and CCW licensing agencies • Permit application information and links For each state, summaries of laws (and links to the actual statutes) for: • Different CCW permits offered and any age or residency restrictions • Permitless carry, open carry, duty to inform • Sign enforceability (including 30.06 and 30.07 distinctions in Texas), rest areas, public parks • Businesses serving alcohol, magazine limits, tactical rifles, state preemption BEAUTIFUL INTERFACE Our modern interface makes competing apps look like relics from another era.

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.
