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
EMET (אמת) — Truth Revealed Through Letters and Numbers Full access to Emet requires an auto-renewing Emet Membership ($1.80/month after a 1-month free trial). Emet is a powerful tool for exploring the fascinating intersection of Hebrew language, Gematria, mathematics, and spiritual tradition. Built around the Hebrew concept of Emet (Truth), the app invites users to discover how letters, numbers, and patterns have been studied for centuries as pathways to deeper understanding. Features Hebrew Gematria calculations and analysis Hebrew letter values and meanings Exploration of numerical patterns and relationships Fibonacci sequence discovery tools Sacred mathematics and symbolic connections Teachings inspired by Jewish tradition and wisdom Beautiful, intuitive design for study and reflection Continuous additions of new content and insights Explore Timeless Wisdom The Hebrew alphabet has long been viewed as more than a system of writing — it is a language of symbols, meaning, and numerical significance. Emet provides a modern way to engage with these traditions while encouraging curiosity, learning, and personal reflection. Investigate Gematria relationships, explore mathematical patterns such as the Fibonacci sequence, and examine how numbers appear throughout nature, language, and ancient teachings. A Journey of Discovery Whether you're a student of Hebrew, interested in Kabbalah, fascinated by mathematics, or simply seeking new perspectives, Emet offers a unique space where language, number, and meaning converge. Seek truth. Explore patterns. Discover Emet. SUBSCRIPTION INFORMATION Emet Membership provides full access to premium features for $1.80/month after a 1 month free trial. Subscription automatically renews unless canceled at least 24 hours before the end of the current billing period.

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.

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.
