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

Transit makes it easy to get around your city. No more waiting. No more guessing when your ride will arrive – our app helps you travel by public transit in 1,000+ cities. With live departure times and real-time vehicle tracking, you’ll always know EXACTLY when your bus or train is coming. With Transit, you can get anywhere without needing a car: • Plan the fastest route from A to B on public transportation • Quickly compare options like bike + rail or bus + subway • Get instant alerts about delays and disruptions • Save your favorite destinations and lines – then plan trips in just one tap! HERE’S WHAT THEY’RE SAYING “Gives you the best route to where you want to go” - New York Times “You won't realize how much time you can save planning until you use this app” - LA Times “Killer app” - Wall Street Journal “MBTA has a favorite transit app – and it's called Transit” - Boston Globe “A one-stop-shop” - Washington Post AND HERE’S THE WORD FROM PUBLIC TRANSIT RIDERS: “Your app was the deciding factor in selling my car.” “Blows Google Maps out of the water.” “The head of our local transit agency recommended this app over the one her agency created.” 6 GREAT THINGS ABOUT TRANSIT: THE BEST REAL-TIME DATA: Using the best transit agency data, GO crowdsourcing data and our in-house ETA prediction engine, we get you the most accurate real-time info possible for all transport modes: bus, subway or metro, train, streetcar, ferry, rideshare and more. Prefer to travel on two wheels? See live bikeshare and scooter locations right on the map. OFFLINE SUPPORT: Bus schedules, stop locations, subway maps and even our trip planner are available offline. When GPS is spotty underground? Use GO and you’ll still get precise ETAs. TRIP PLANNING PAR EXCELLENCE: See fast and easy routes on buses, subways and trains, and even multiple modes in one trip (bus + bike or scooter + metro). Personalize your journey planner in the settings: skip long walks or the modes you’d rather avoid. It’s like using the MTA Bus Time, MTA Train Time, NJ Transit MyBus, SF Next Muni, CTA Bus Tracker, WMATA Next Arrivals, SEPTA app – all in one! GO NAVIGATION*: Use GO to receive departure alarms to catch your bus or train, and get alerted when it’s time to get off or transfer. You’ll also contribute more accurate info and real-time ETAs for other passengers – and rack up points for being the most helpful rider on your line. CROWDSOURCED WISDOM: See what millions of riders say about crowding levels, on-time performance, the best station exits, and more. EASY PAYMENTS: Pay your transit fare and buy bikeshare passes directly in the app in 100+ cities. *Continued use of GPS running in the background can decrease battery life.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

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

Implement a more reliable data source with better accuracy.

Assumption to check: Inaccurate real-time data leading to user frustration

Validate with people who use this workflow before building.

Hypothesis 2

Provide downloadable offline maps and schedules.

Assumption to check: Limited offline functionality

Validate with people who use this workflow before building.

Hypothesis 3

Streamline UI to focus on core navigation features.

Assumption to check: Cluttered interface with too many options

Validate with people who use this workflow before building.

Hypothesis 4

Optimize app performance for better handling of peak usage.

Assumption to check: Inconsistent performance during high traffic times

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.
