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.

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 GPS error handling and smoothing algorithms.

Assumption to check: Inaccurate speed readings in areas with poor GPS signal

Validate with people who use this workflow before building.

Hypothesis 2

Allow users to customize the color and layout of the speedometer.

Assumption to check: Limited customization options for display

Validate with people who use this workflow before building.

Hypothesis 3

Enable offline storage of trip data for later access.

Assumption to check: No offline capabilities for historical data

Validate with people who use this workflow before building.

Hypothesis 4

Introduce gamification elements like achievements for tracking milestones.

Assumption to check: Lack of user engagement features

Validate with people who use this workflow before building.

App Store description

Speedy is a very effective and easy application to help you to calculate your current speed and distance that you have covered. Speedy designed gracefully and freed from elements that might cause difficulty for you. -----DESIGN INTEGRITY----- You can access all the settings and information windows that you need with buttons which will be appeared when you touch the screen once while using Speedy. To preserve the design integrity, these buttons will be invisible again after five seconds. -----MEASURE YOUR SPEED----- Speedy measure your speed most accurate way possible by using GPS and available cellular and wi-fi networks. Maximum speed value and speed ranges are automatically increased or decreased in speedometer based on your current speed. -----MEASURE THE DISTANCE YOU HAVE COVERED----- Speedy can measure the distance that you have covered and display it prefered measurement unit with the odometer where placed in speed gauge and also keep measuring even application works in background. (Background distance measurements, depends on whether you have given permission to the application to work in the background.) -----SPEED LIMIT EXCEEDED ALARM----- Using the speed limit alarm feature offered by Speedy you can determine a speed limit and you will be warned a visual and audible way when you reach the speed that you've set. -----SPEEDY WILL WARN YOU EVEN IN BACKGROUND----- Speedy can alert you via notification when you reach the speed limit that you specify previously even application not working. (It depends on whether you have given permission to the application for work in the background and receive notifications.) -----YOU CAN SHARE YOUR SPEED----- Speedy gives you possibilities to take the screenshot of the application and save it to the camera roll or share with others directly or via social networks. -----HEAD-UP DISPLAY (HUD) MODE----- Speedy can reverse the speed gauge to be seen properly from the reflective surfaces. You can reflect and follow this pretty nice and functional speedometer application on the windshield of your car without take your eyes off the road. enjoy :D Please keep in mind, Speedy will interpret the informations that obtained from your device sensors and receivers such as many other navigation applications do. And these data provided by your device may not be trustworthy at vital conditions. Also, continued use of GPS running in the background can dramatically decrease battery life.

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.
