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

Stores mark items down to a penny. They just don't tell you which ones. Penny does. Live clearance, real price mistakes, and the $0.01 finds that never make it into an ad — with the aisle and bay, so you walk straight to the shelf instead of wandering the store. PRICE GLITCHES Real pricing errors, caught while they're still live. A 65" 8K TV at $1,977 that should have been $5,299. An electric scooter at $601, down from $1,399. These get fixed fast, so you hear about them fast. IN-STORE CLEARANCE Home Depot markdowns at the store you actually shop — down to the aisle and bay. Most finds save more than $50. No app tells you where the item is standing. This one does. PENNY LISTS Every week, items at Dollar General, Dollar Tree and Family Dollar quietly drop to $0.01. We publish the list before they're gone. BARCODE SCANNER Point your camera at anything to see the real clearance price. The shelf tag is wrong more often than you'd think, and it's almost never wrong in the store's favor. SAVED DEALS & ALERTS Save what you're hunting. We'll tell you the moment the price moves. DISPONIBLE EN ESPAÑOL Toda la app está en español, no solo un botón traducido. Ahorrar no debería tener barreras de idioma. MEMBERSHIPS Free — Weekly clearance events and online deals, 5 scans a day Penny Pro ($14.99/mo) — Live price glitches, the Dollar General, Dollar Tree and Family Dollar penny lists, 25 scans a day Penny VIP ($29.99/mo) — Everything in Pro, plus local Home Depot clearance with aisle and bay, penny watch, and unlimited scans Privacy Policy: https://pennydeals.app/privacy Questions? pennydeals.app Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Expand categories and include more niche deals.

Assumption to check: Inconsistent notifications for deal alerts.

Validate with people who use this workflow before building.

Hypothesis 3

Simplify design and enhance navigability.

Assumption to check: User interface feels cluttered.

Hypothesis 4

Integrate more social platforms for sharing deals.

Assumption to check: Limited social sharing options.

Validate with people who use this workflow before building.

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.

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.
