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

Enhance with a broader database of locations and tidal data.

Assumption to check: Limited location data for tidal information

Validate with people who use this workflow before building.

Hypothesis 2

Integrate a feedback mechanism to improve user engagement.

Assumption to check: No support for user feedback or reviews

Validate with people who use this workflow before building.

Hypothesis 3

Implement push notifications for significant tide changes.

Assumption to check: Lack of notifications for tide changes

Validate with people who use this workflow before building.

Hypothesis 4

Add onboarding tutorials to guide new users through the app.

Assumption to check: Not user-friendly for beginners

Validate with people who use this workflow before building.

App Store description

Tides Explorer — Accurate Tides, Currents, and Marine Weather Tides Explorer is a precision tide and current app for sailors, boaters, paddlers, and swimmers, built on official NOAA data covering over 6,000 stations across the United States and international waters. It helps you understand not just what the water will do, but when and why, using clear charts and reliable predictions you can plan around. Core Features Get accurate tide and current predictions straight from NOAA, with fast search by name or location and interactive charts for exploring and comparing stations. At supported stations, see real observed water levels laid over the prediction (Pro) — so you know what the water's actually doing, not just what it's supposed to do. Save your favorite spots for quick access (Pro), track real-time weather at supported stations — wind, air and water temperature, and barometric pressure (Pro) — and check sun, moon, and twilight times to help plan your time on the water. Plan Around What Matters to You Drag a custom reference line onto any favorite station's chart — on a current station, mark a safe velocity to catch slack water before transiting a pass — and see exactly when you're above or below it. Set alerts for high and low tides, current extremes, your reference line, or slack water itself (Pro), plus new Moon Over Water alerts for when moonrise or moonset lines up with the water near sunset or sunrise. Designed for Apple Platforms Tides Explorer includes Home and Lock Screen widgets and a full Apple Watch app with multiple complications, all optimized for iPhone, iPad, and Apple Watch. Built for the Water Ideal for sailing, boating, kayaking, swimming, fishing, and coastal exploration, Tides Explorer delivers dependable marine data without clutter, so you can plan confidently and focus on the water.

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.
