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
DebtLens turns debt tracking into a quick monthly habit. See total debt, month-to-month movement, and payoff momentum in a focused visual dashboard designed to help you understand the numbers and move on with your day. UPDATE BALANCES FAST Run a guided monthly check-in for every account. Review the previous balance, enter the latest amount, choose No Change, or mark an account Paid Off. Finish with a clear recap of debt reduced, debt added, and estimated interest. SEE PROGRESS AT A GLANCE Read the debt trend chart first, then review total debt and recent activity. Tap into accounts for balance history, utilization, payment details, and a full breakdown. BUILD A PAYOFF PLAN Adjust an extra-payment slider and instantly compare projected debt-free dates and interest. View Snowball and Avalanche side by side, with a recommendation based on your saved accounts. KNOW EACH ACCOUNT Track due dates, APR, minimum and target payments, statement balances, credit limits, and autopay status. Credit cards show utilization, while loans estimate principal and interest. PRIVATE, PERSONAL, AND PORTABLE Use DebtLens without creating an account, or sign in with Apple to sync through iCloud. Add an optional Face ID or device-passcode lock, schedule a monthly reminder, choose a premium light or dark theme, and export a themed PDF report with the accounts and date range you select. Payoff dates, interest, and principal estimates are informational projections based on the data you enter. DebtLens does not connect to financial institutions and does not provide financial advice.

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.

Intermediate
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.
