Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
DNAVault lets you explore your genetic data — kinship, ancestry, health, and more — entirely on your iPhone. Your raw genome never leaves your phone. Other companies sell you reports, which means they read your data. DNAVault reports are generated on your phone. When any server processing is required, it happens inside a cryptographically attested enclave, encrypted with a key only your phone holds. Nobody can read the result but you. Not by policy. By math. FEATURES • Kinship Analysis — compare genetic data with someone nearby using end-to-end encrypted proximity sharing, phone-to-phone. Nothing is retained after analysis. • Origins — trace your paternal (Y-DNA) and maternal (mtDNA) lineage back thousands of years using Yleaf and mitoLEAF haplogroup classification. • Health — screen 81 ACMG medically actionable genes, pharmacogenomics, and clinically significant variants against a local ClinVar database. • Ask — ask plain-language questions about your genome. Only the text of your question is sent; your genome stays on your phone. SUPPORTED FORMATS • AncestryDNA raw data • 23andMe raw data (v3, v4, v5) • Whole Genome Sequencing — coming soon PRICING • App: $2.95 one-time • All on-device features: free forever • Ask AI: free for 30 days, then $2.95/month or $19.95/year Privacy Policy: https://dnavault.starfleetbio.com/privacy/ Terms of Use: https://dnavault.starfleetbio.com/terms/

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.

BUILD KIT DIFFICULTY
Advanced
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.
