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 a calibration feature for users to improve accuracy.

Assumption to check: Accuracy of GPS measurements can vary based on location and environment.

Validate with people who use this workflow before building.

Hypothesis 2

Provide more customizable unit options for distance and area.

Assumption to check: Limited unit options may frustrate users.

Validate with people who use this workflow before building.

Hypothesis 3

Allow users to bookmark frequently used measurements.

Assumption to check: No option to save favorite measurements.

Validate with people who use this workflow before building.

Hypothesis 4

Include social sharing features to allow users to share their measurements easily.

Assumption to check: No sharing options for measurements.

Validate with people who use this workflow before building.

App Store description

Measure land, roads, parks, countries, lakes, etc from a satellite view. Calculates distances, areas, and perimeters. Features that this application offers that most competitors do not: - Add custom distance and area units. - Draw interior polygons. For example, land area with bodies of water removed. - Add a point to the middle of a path (Most only allow you to add to the end of the path) Tap to add to the end of a path. Long press to add to the middle of a path. - Swap two points in a path or polygon. - Add your current location from GPS receiver. Features: - 3 map layer options - Export and import .kml files via Dropbox, iCloud, email, etc - Pins are draggable and manually editable - Name, notes, and color fields for each path and polygon - Email or text message path and polygon data - 4 verbosity modes. See only the information that you want to see - Search by postal code, city, address, etc - Get addresses near point on map 4 drawing modes: - Path - Polygon - Polygon with hollow spaces inside - No edit mode (to prevent accidental edits) Values displayed for paths: - Total distance - Incremental distance for each waypoint Values displayed for polygons: - Area - Perimeter - Distance for each side Add points to a path or polygon in 1 of 4 ways: - Tap on the map - Use current location - Enter coordinates manually - Import .kml file Default distance units include: - Meter - Foot - Yard - Kilometer - Mile - Nautical mile Default area units include: - Square meter - Square foot - Square yard - Square kilometer - Square mile - Square nautical mile - Square acre - Square hectare Coordinate formats: - Degrees - Degrees, minutes - Degrees, minutes, seconds - UTM / UPS (Universal Transverse Mercator) / (Universal Polar Stereographic) - MGRS (Military Grid Reference System)

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.
