Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

See where your money really goes -- without compromising your privacy. SpendingLens turns your PDF bank and card statements into clear, actionable financial insights.

No accounts to create. No bank passwords to link. No subscriptions. Just private financial clarity right on your iPhone and iPad. ---------------------------------------- WHY SPENDINGLENS? ---------------------------------------- Most finance apps require linking bank accounts or uploading statements to remote servers, exposing sensitive transaction history to third-party aggregators and advertisers.

Your financial data remains entirely yours. ---------------------------------------- KEY HIGHLIGHTS ---------------------------------------- 100% PRIVATE & ON-DEVICE - Zero tracking: No ads, no third-party analytics SDKs, and no cloud servers. - No bank logins: Works directly with the PDF statements you already have. - Local storage: All transactions and rules are stored securely on-device with SwiftData.
